Mr. Lewis is a nice guy who works hard to try to present the information clearly. However, he sucks at it. Maybe it's not his fault, but I constantly found people in the class correcting his mathematical errors. He doesn't explain anything-he simply writes the solutions on the board. If you have any questions, he can't think of any other way to explain it, so he says the same thing all over again. I was constantly confused in that class and found myself teaching the material to myself, which, believe me, is really hard. I got the general feeling that he really didn't care about the students. If you get him, please drop his class. I don't want you to have to go through what I did.

Where do I begin. I had taken Pre-Calc in high school, so his class was a breeze. I didn't go half the time, and the other half, I went to sleep in class. The guy is a pompous ass. I do have to say that he is pretty funny, but not in the way he tries to be. His jokes are pathetic, but they are so bad that you end up laughing AT HIM anyway. The one good thing is that your grade consists of five tests. The final is optional and only replaces your two lowest test scores if it helps you. Like I said before he is a pompous ass. Anyway, I'll stop my rant and get to the point. DON'T TAKE HIM! Run and run fast!

I had not taken Calc before in high school, and I spent the whole quarter wondering what a derivative was. He gives very little problems from homework and puts them on the quizes. However, quizes don't count that much. His exams are really hard and there's only 3 problems. I got lucky and aced his final

Lewis is very fair. He tells you exactly what you should know. He has daily homework but it is never collected so you are on your own to do it. There is a 10 point quiz every Friday and 3 midterms. He drops a low grade or two. He gives a solid back ground in calculus 1.

OKay. I passed the Calc BC AP exam... and I still took 141... Why? I thought I would need review, but I talked to some 142 students and they said that I didn't. After geting this outta the way, you know that I had experience in calc before. Then why am I doing so horrible in his class? I say horrible because I didn't take the final yet. I believe I may have a C right now. I say A because I'm going to ace his final even if it kills me. Take everybody's advice. Do not take this prof unless you have experience already. I don't blame it too much on him though... I just needed more time on his mid-terms but the 50 minutes class would cut me short.

I had calc in high school, which made it easier to understand, but I feel bad for the people who didn't have any prvious experience in calc. He is very confusing and has horrible tests. They consist of 4 problems, 3 which are cake and 1 which I couldn't do. I recieved A's in high school and in math142. If you had clac before his class is cake if not take another teacher. Oh he assigns 5 problems of homework a night which takes 5 minutes.

I thought Professor Lewis was a mass good calc teacher. He taught you what you needed to know and did not give you a lot of useless junk. His quizzes were nice to chart your progress and usually contained two problems from the homework. His midterms were quite reasonable and I liked the fact that he let me avoid the final because I had an A. If you do all of the homework you should have no problem with this class, although he is a bit boring. One last thing: This guy is a comic genuis. I hated how no one but me ever lauged at his jokes.

If you have never taken Calculus before, DO NOT TAKE IT FROM PROFESSOR LEWIS!!! You will be completely lost unless you already have some experience with what he is teaching. He also has this philosophy that "Students need to be allowed to fail," which really intimidated me, but I guess if you keep up with (and actually understand) the homework and study efficiently, there are not many surprises on the tests or quizzes. In all fairness to the man, I must say that it is obvious he knows the material he is teaching. He just doesn't always teach it clearly to students. And some of his attempts at humor are actually kind of funny. The bottom line...I only got a good grade because I had a good Calculus teacher in high school.

Dont believe the idiots out there who got A's. They most likely had calculus background and alreayd knew what they were doing so they're arrogant to say "you didn't work hard enough if you didn't do well." i worked my ass off in his class. His lectures were monotone and he couldn't present the material in more than one way. Since taking his class i have had FOUR other math teachers, ALL of whom were far better than Lewis. (including Sze, Girolo, VanEps, and one other guy i cant remember heheh) If you dont alreay know what you are doing, be prepared for a difficult quarter.

I passed the calc AB test, but decided to retake calc I. Had I not already taken calc I would have been completely lost. His lectures were presented in a dead monotone and he was a very picky grader on tests. For his good points, he will go over any homework question's meticulously and he does not collect homework. His tests contain about 4 problems and are horrible if you haven't done the homework. Also, if your grade sucks he may make the final worth a large percentage of your grade. Not a bad class for an early morning nap.

Dr. Lewis does have a tendancy to be monotoned in his lectures but he does cover all the material in a slow and step by step method. He does not collect homework so if you are a procrastinator like me who likes to do your homework when you feel like it and not when it is due then he is a good professor to take , he does however give a quiz every friday with 2 problems which usually come straight from the homework. His midterms are fair but can be hard, the only down fall for them is that they only consist of 4 problems so if you dont know something you may be in trouble. Dr. Lewis does have a great loophole though that could save your entire quarter as it did mine. He will make your final be your entire grade for the quarter if you score well. All i can say is i must have got a B on that final because it saved my life.

It is very difficult to hold the hard feelings back from my experience with this Professor. Dr. Lewis made a point to boast about his extened term here at Cal Poly. I believe it is this characteristic and the fact that he has taught all thirty plus years of service the "same exact way". Reguardless of the response (questions) of the particular class, he was only able to present his course material in one way. This was upmost frustrating when you don't understand his example and ask him explain it again; and he chooses to do it all over the same way -I don't see the advantage of this method. After reviewing the tests and quizzes the pattern I found was that the material that he found important enough to hold you accountable for were the exceptions in Calculus and not really the vital stuff pertinent to Calculus II. Dr. Lewis (in my opinion) is somewhat responsible for my difficult first quarter adjusting as a freshman. I was confident enough to make the judgment that I knew enough Calculus (I took AP Calc in High School) to continue onto Calc II, while retaking Calc I (with another prof. -obviously) where I am currently doing well in each section. I suppose not everyone did as poorly as I did, so I don't want to say that it is impossible, but if you are not a Math major, then I would not recommend this DINOSAUR of a Professor.

It was obvious the instructor has fallen into the same routine for years and years, and, being unable to present the material in more than one way, it was often difficult for many students in his class to grasp the concepts. I do not reccommend this teacher, espically if you have difficulty in math: you will not do well in his class.

Dr. Lewis is joke. ***** He can't present the material at all. He lectures are very monotone, more than any other professor ever. He is too old to be teaching and talks about how people are coming from outer space to attack us, etc. He doesn't collect homework and his tests are extremely hard. He gives no credit for all or most work. You must have the correct answer or it is wrong, all points off. He does not help you in office hours, just criticizes and tells you to change majors. I am C student now and trust me he has no idea what he is talking about. How he got his PHd with his attitude, I am not sure. DONT TAKE THIS MONSTER, **** AND SOO SOO HARD!!!!!

This guy is sooooo dry. I took Brief Calc in high school and did pretty well. I understood the material well enough to atleast make a B in the class. But his tests are very hard, and only like 3 problems- so if you dont know one, hey guess what you fail. Also there tend to be quite a bit of word problems on the tests, and he hardly ever goes over word problems in tests. I suppose you will come out of there understanding the material, but your grade wont reflect how well you know it due to the toughness of the test questions.

Lewis is way too old to be teaching. He should have retired years ago. The quizzes and midterms are easy if you don't make mistakes but Lewis is way anal about simple mistakes. He doesn't grade homework and he doesn't explain the work. He just rambles on for an hour on how his wife won't let him pet the skunk that always visits them. I remember he told our class once that everything he taught us in 141 would be left up to the teachers in 142 to correct. i didn't know that that was the new policy for teaching. Seriously avoid lewis at all costs.

Dr. Lewis if FOR SURE the worst teacher i have EVER had. He did not explain ANYTHING ever. The only place that I learned anything was in my workshop, I strongly recommend being in a workshop for his class. His midterms are actually impossible. They are 3 of the HARDEST questions from the hardest sections, and no matter how much i studied, I didn't have a chance to score better than a C. Not only all of that, he has the most monotone voice and NO social skills whatsoever. He couldn't communicate to save his life and he has NO understanding of what the students' needs are. AVOID DR.

if it wasnt bad enough that he is boring, he FORCES YOU TO BE IN CLASS EVERYDAY, not matter what, you cannot miss a single class or he will srop your grade automatically 1/3 of a grade, so if you sign up for his 8 am class, be prepaired to hate life.. he tries to be nice, and allow you to drop tests and things of that nature, and he never collects HW, but in all honesty he has to cut us breaks because the tests are so difficult, that your grade will be crappy no matter what.. simple as that..

Prof. Lewis is a obviously a brilliant man, understanding and enjoying his feild greatly. However, he is not a great teacher. He mumbles, he doesn't address the class at all, he is hard of hearing and therefore hard to get the attention of, and he is dry and monotone. Do not take this professor if you have never taken calculus before, and even if you have and you want to review it before moving on (like myself), you had better be confident of your previous skills. He assigns all the homework from the very first day, just a few problems for each lecture, and the homework for the week is represented on the weekly quiz. He asks for any questions on the homework at the beginning of class, but he often just does the problem and does not explain the why. He is better in his office hours simply because you can recieve his full attention, whereas in class you have absolutely no attention whatsoever. He obviously has been teaching for quite awhile, because his lectures are so structured that it is obvious he has done the same lecture all day long and quarter after quarter. He is extremely bad at helping the individual, or even problems that most individuals have. His class is possible, but not easy in its own respect or made easier by him. I strongly state that if you are not gifted in mathematics or have not already been familiar with this material, you should not take this teacher as your introduction. However, if you must, make sure to visit office hours and force him to pay attention to your questions and needs.

Dr. Lewis is only a good teacher if you took calculus in high school before. If you haven't taking calc before, you will be very confused. He goes over the sections very fast and speaks in a monotone voice. His voice will put you to sleep in a jiffy. To top it off, he has awful jokes that make you want to stab your eye out with a pen. Also he has quizes once a week. He is also generous enough to replace your test scores with your final, only if you did better. However, if you alread taken calculus before this guy is great because it helps support your already aquired calculus skills. Overall I felt I came out of the class feeling better with my calc skills. ONLY TAKE THIS GUY IF YOU TOOK CALCULUS BEFORE.

prof. lewis is a NICE man, regardless of what people say. he may be a tidbit dry and boring in class, but i mean its MATH, its GONNA be BORING regardless of WHO u get! there's NO fun way of conveying math to students!!! but IF u actually pay attention to lewis in class instead of fallin asleep or skippin, you'll find that u will actually LEARN something. ive taken calc141 in high school and i had a HORRIBLE teacher, and his tactics weren't good. but lewis has good tactics in conveying the material, you may not realize that because its new stuff. his class consists of weekly quizzes with two or three problems straight from the homework, and the homework isnt too many problems. then we have two midterms or so, but the problem about the tests is that it consists of four problems only. however, these problems arent problems that are made up and really hard, they're mainly liek the homework type of problems, just different numbers. then the final consists of four to six problems as well, but same concept as the test. so not too stressful. take him! he's a lil boring, but thas not his fault.

Lewis' 141 class was NOT that bad at all. I've never had ANY Calculus before and I easily got an A in his class. All you have to do is work out the practice problems he gives, which anyone with half a brain could figure out, and problems just like them will be on the quiz or the tests. This class is an easy A for anyone willing to go to his lectures... boring as they are, and know how to do the basic calc problems.

Lewis is a chill dude and his class is very structured and predictable - no curve balls or surprises, which I really appreciated. There isn’t a review on him on here since 2005 so I hope this helps haha. He only taught one class when I had him because he seriously should be retired (almost 80 years old). Would not really recommend taking him if you don’t have any prior knowledge in basic calculus; he kind of just assumes everyone knows how to do some stuff which I would've been pissed about if I didn't know. On the other hand, I know people who hadn’t taken calc before, joined a study session, and are doing just fine. Dude is an absolute genius and knows like the entire history of math (which leads to some long tangents in class). 2 tests that were pretty straight forward, a challenging but fair final, and 2 homework quizzes/week. Very straightforward.

Where to begin with Professor Lewis. My first impression of this teacher is that he is most definitely a smart man who has loved calculus for 60+ years and he really knows his stuff. But his ability to articulate his knowledge coupled with the fact that I had his class at 8:00 AM really was unfortunate. The workload for the class is not bad at all as he only gives quizzes on homework assignments and doesn't check what you do at all. This is dangerous if you have the solutions because you will only really look at the solutions and not actually learn the material for the midterms and final. The midterms are relatively simple so long as you know the material to a decent extent and did more than your fair share of the homework. I looked at the solutions, and I got F's on the 2 midterms. And he straight up told me after giving me back my second midterm that he knew I was sleeping through class and not trying at all and was "more than ready to fail me". Now, this brings me to the best part of Lewi's class. If you have a 0% in his class and get an A on the final(as long as you have taken both midterms) your grade in the class is replaced with the final. Now, I don't recommend banking on this as it puts a lot of stress on that one test however, it really helped me and was inevitably the reason I passed the class after slacking all quarter. Overall, Lewis is a man who understands calculus well, but it is difficult for him to articulate it well as he makes everything more complicated than it needs to be. I feel to take his class you really need to be a self-starter that can manage studying relatively hard to get the grade you want. Hope this helps!!!

Lewis was an interesting teacher. I felt like I was constantly struggling in his class and I was bored stiff by about 90% of the lectures, but I can't help but like the guy. Well, at least in some sense. He has an under-appreciated sense of humor that is unfortunatly only invoked about once a week. I would only recommend him in a class that you are already pretty familiar with. But he gave me a C when I deserved a D, so he can't be all bad.

Dr. Lewis is very familiar with the course material and thus able to explain it very thoroughly and clearly. His tests and quizzies were very fair because the problems on them were very similiar to homework problems(which he goes over at length in class if you ask him). I think the main problem people had with his class is that is can be boring sometimes, but if you follow along and understand the homework problems, you will do well.

Dr. Lewis is simply the whole reason that I go on in math. At first, I hated math and dreaded the fact I had over 5 quarters of it left. Then I took Lewis, as he allows us to call him. He was more like one of the boys than one of the faculty. Anyone who takes Lewis for math should consider himself lucky for being able to get it. From the homework, which is thoughtfully assigned and not collected the quizzes taken straight from the homework, the midterms which are anything but impossible, his style and comedy Lewis is by far the best Math prof. I have had. He didn't teach 143 or else I would be in there for sure. Lewis, if you're reading...thanks a lot for a great quarter. P.S.- Notice that the negative comments that bring Lewis' rating down are from those who received poor grades. I can guaruntee that those people earned every bit of their crappy grades.

Dr. Lewis is a great teacher who uses an incredibly fair and straightforward grading policy. Anyone who fails this class does so because they did not take the initiative to do the homework and go to class. His homework assignments (which are not collected) are well thought out as to bring up the important points of the section without beating you over the head with them. The weekly quizzes are straight from the homework so they are basically free points to reward students for doing the homework. The midterms are very fair and should not pose a problem for anyone who puts in a reasonable amount of study time. The final was difficult but not impossible. On tests and quizzes he gives partial credit all over the place if you make simple mistakes at the beginning of a long problem. The best part about Dr. Lewis, however, is his unique sense of humor. This guy is hilarious. I was often disappointed at how some of the people in the class did not appreciate his class for how fun, easy, and instructive it was.

Professor Lewis is a pretty good teacher. Once you get used to his teaching style the class isn't too bad. Sometimes he may seem boring, but he is also pretty funny. He is really nice about answering all homework questions that students have during the beginning of class. Homework is not worth points, but make sure you do all of it!

I would say he's an average professor at presenting the materials, I don't expect anyone can present math materials in an interesting way. His quzzies and midterms and final are basically from the homework problems, they are do-able.

Dr. Lewis has a weird sense of humor. He has very old fashioned and believes that girls should get the seats first while the guys stand on the side of the room trying to crash or even if you are enrolled, let the girls sit or he will not continue with lecture. During lecture, he has his good days and of course, his bad. Those days, you have to learn from the book. He gives weekly quizzes that are basically 1 or 2 homework problems (the exact same ones, no number switching). His tests are reasonable, no surprises. The kicker is that even if you fails every test and every quiz, if you get a C or higher on the final, that's your grade. It is awesome because sometimes it takes that long just to put everything together. Plus, the final seemed easier than the midterms. I recommend him because I learned a lot plus he's cool!!

I've found many of these polyratings to be filled with opinions of whinny children who want a prof to wipe there ass because the thought of putting any form of effort into a class is unbearable. If you want a prof to do the work of jamming information into your head for you, then Dr. Lewis is not one I would suggest for you. The material IS hard. You WILL need to work on your own. However, if you are polite (God forbid), he'll GLADLY help you with anything in his office hours. I'll admit that his lecture is dry and a little slow, but the class is about the material, and not every prof can (or wants to) jabber about some unrelated event in their life between ideas. If you have the mindset and desire of learning the material, you'll be satisfied with Dr. Lewis. If you want a joy ride out of the material, then look elsewhere.

Not to rip on Lewis, but he's a bad teacher. For students who (in high school) worked their asses off, read and thorughly understood the book, and did well, maybe you'll do alright. However, his lectures ARE NOT helpful in learning the material, only in giving you a base of the topic with which you can TRY to dissect the solutions manual and figure out what the heck it did. His weekly quizzes are easy, they contain a few problems directly from the homework assignments (HW is not turned in). However, his midterms are not easy, and i can honestly say i studied my ass off for them, did all the homework, and averaged a 51% on the midterms. Then the final is the same deal.. and thus i did not pass and am taking it again FROM A BETTER TEACHER. Learn from my mistake, don't take Lewis.

He loves math, but he can't teach. His tests are extremely specific when it comes to testing you on what he taught. Be prepared to know EVERYTHING that he taught that quarter; down to the smallest detail. I aced the second midterm and still got a C in the class. He spends most of the period teaching you proofs and lecturing on the history of mathematics rather than teaching how to do the actual problems and apply them to real world situations. If you enjoy math and understand it well, you might enjoy taking him. If you're and engineer and simply need to master the techniques the class is supposed to teach, find another teacher.

Also, he wears the same thing every day and doesn't move his lips when he talks.He should be a ventriloquist, not a professor.

Everyone is going on about how terrible he is and I don't think he's nearly as bad as they say. Actually I think he was all in all a pretty good teacher. In the few short quarters I've been at Cal Poly since transferring I've noticed that students here are spoiled by the quality of the staff. I've had some terrible math teachers/ teachers in general at the community college I came from. I think that Lewis (who took over for this class in an hour of desperation midquarter) presented the material clearly. He tested on what he covered and didn't expect anything unrealistic from us. Even though he stepped up to teach this class after 20 years of not having taught it, he still did a better job than some of the fill in teachers we had before him. Words of advice...if you want to have a good experience with Lewis try to not be a dumbass.

I used to be good at math, and believe it or not enjoy it before I had Lewis. He has a very difficult time presenting material clearly. His lack of personality and desire to help one make it worthless to go to his office hours. Avoid him if you can.

Lewis was awesome. knows the material damn well and cuts right through the bullshit to the stuff you really need to know. it was kinda weird having him skip sections. but if you look at the sections he skipped, theyre pretty easy to understand. the way he presents the material is very logical and its easy as hell to follow him step by step. homework was cake and the midterms and final were just as easy. he prepares you quite well for them. even though it's easy, you come out knowing your shit.

Lewis is a very dry lecturer. I had trouble staying awake in his class, despite my efforts (and sitting in front) for he speaks in a sedatively monotone voice. He does not explain things, he simply does problems out of the book. Also, he takes off way too many points for what he considers to be "lack of clarity" (incomplete sentences).

I would give this guy an even better grade had I gotten a better grade. I think I'm just pissy and a bad tester. Seriously though, he's a pretty basic fellow with a basic approach and a basic grading system (like every other damned teacher in this school they put way too much value into the final). Thus far he's the best math teacher I've had (aside from my high school calc teacher, but I don't think anyone will top him. He was godly). I'm gonna try for him next quarter.

Let me first start by saying that I'm horrible at math but Lewis made it more accessible to me. I had him for both 143 and 241 - and if he taught 244 I would take him again in a heartbeat. Lewis is not the best at lecturing - he basically goes over just conceptual stuff - but he makes it relatively easy to understand. If you don't get it, all you have to do is ask him. He does a good job of explaining things; and if you still don't get it he'll explain it again a different way. Lewis assigns homework but its not collected. Everyday in the beginning of class he takes questions on the homework and does the problem through completely. We have quizzes every Friday (two questions) - but they are questions straight from the homework (the homework takes no more than 20 minutes a day). The mid terms and final follow the same difficulty as the homework questions, so there are no surprises. I think Lewis is the most underrated teacher here. He's been one of the best math teachers I've had.

His tests and quizes are not hard or tricky, but I'm saying it's easy. If you can do the homework, you'll be able to pass his test. I don't know about others, but it was an easy A for me.

I understand why people have a hard time in his class. He is very educated and sometimes has trouble talking down to the students who really shouldn't be in college. He will explain things many times in many different ways, but you have to ask. If no one asks questions he will assume you don't have any (not that that should be any news for you). The quiz questions are word for word and number for number off the homework, so DO THE HOMEWORK! He is very willing to work with students (he let me take the final early so I could go home early), but again, you can't be afraid to ask. Overall, if you have a decent understanding of math and actually deserve to be in college, Lewis is a good choice as a professor.

I was worried about taking Lewis after seeing his Polyratings score, and then I got to class. I can't understand why everyone tears on him so hard. I understand those people that can sit down in a lecture and just 'get it'; I am one of those people. But it's an advanced mathematics course. You don't learn it from listening for a few minutes in a day. You do the reading, you do the work, you actively seek to understand. A lecture like this is a /supplement/, not a full education. If you don't understand that concept, you're the one with the problem. I thought his lectures were solid and very interesting, assuming you /take/ an interest; not to mention, he's really quite funny in a dry kind of way. And his tests are relatively easy. He doesn't throw curveballs or obscure applications. If you took the time to do the homework, the tests are a cake walk; straightforward and to the point. Overall, I rather liked him. You just have to be prepared to do some work, and I'm sure that's true of any Calc class you'll ever take.

I basically used Cramster to get through this class. His lectures are not that great--there were maybe two techniques I learned from him that I didn't learn from the book/homework. The homework is optional and is an average amount if you do it all. You'll have several H.W. tests, two midterms, and the final. Homework tests take problems straight from the homework, midterm/final are questions based off h.w. problems. So it's pretty straightforward. He'll answer any homework problem in class. Oh, and he's old and his humor stinks.

this class was very easy compared to all the other calc classes. you have a homework test every friday and it comes straight from the homework. hes very bad at teaching, he even admitted that himself. even though the homework is optional, you need to do the it to pass his class. i would recommend him only because his test grading is easy. other than that he pretty much sucks.

I sure regret taking him. This is the type of instructor that makes you wonder if you really want to stay at Calpoly. I hate Math now. I had a 3.9 GPA, now I have a 2.5 because of him and his sorry teaching and ways of life. He is very mean and weird. Avoid this guy no matter what you have to do!!!

OK, here's the scoop with Dr Lewis: Direct, Monotone, paces back and forth, bad jokes, very clear. If you do good with an instructor who can teach by doing instead of teach a theory, you will thrive with Dr Lewis. The best thing about his class is that he prepares you very well for the tests and quizzes. The quizzes are taken right out of the homework and there are no, and mean no surprises on the test. Pay attention, do your homework, and put up with the bad jokes and pacing and you will learn and do well.

Lewis takes a while to get used to, but he shows you what he wants you to know, and then asks you to repeat it. There are no suprises on either the quizes or the tests. If you want a teacher who cuts through the crap and focuses on the simple important topics, take Lewis.

I took Math242 as a sophomore, and math 141 as a freshmen with lewis. I figured I was looking through polyratings and checked his grade. I think Lewis is a better teacher than you guys are giving him credit. I thought he was fair in his grading, and the hw's weren't too bad. The only problem I can recall is the test questions will be really easy but 1. The 1 test question will pretty much determine if you get an A or a B. I did great in 141 since I took calc in high school. Math 242 was easy except for the bacristichrone problems which no one could do in the class. one problem took 1 hr to do...and was very difficult. He did not test the class on this subject, but wanted us to be exposed to the type of problem. I thought his final was very tough in that class, it seemed like I worked through the problem to the best of my knowledge to get an answer that didn't make sense. Two people I knew and myself walked into that final with a solid A. We all walked out of math 242 with B's.

if you want an eash A take this guy. he sucks as a teacher if you compare him to other people. he only teaches a little more than i would a say 60% of the material as the other guy who failed me. your final can be 100% of your grade. and for real, his final is really like a quiz if it were another teacher. if you're taking 244 just for support, take him.

The class was an easy A. I did all the homework (which is only a few problems a day) and got a hundred percent on 5 tests. I spent only a little bit of time studying for each test and they were EXACTLY like the homework. I found it a whole lot easier than any calculus course. Although to be fair, I didn't learn too much. I have no idea what we learned or what the course was about. Dr.Lewis is pretty boring and slow, and he struggles to help students when they don't understand a concept. However, he is very nice, go to his office hours for help if you don't understand something, do the homework and you'll do fine.

I took this Linear Analysis 1 class during fall quarter of 2011. George was a very uninteresting professor who did not present the material in a clear manner. His class was comprised of 5 tests (optional uncollected homework) , all of which were weighted equally. He did not make this clear in the beginning of the course. I found it to be unsettling that there was no comprehensive final in this class, as I believe a comprehensive final in math is vital because it gives students more time to learn the material. On the other hand, once the material was covered it was not tested again. Of his five tests, he says that one is dropped from your grade. Even with one test dropped, I was on track to receive a D in his class. Due to a unstated final curve, I received a C. I do not recommend taking this professor unless you can do a lot of self learning and can pick up math material quickly for each test.

Worst teacher I have ever had in my life. I got an A in Honors Calc IV and had to teach myself the entire subject of linear I on my own to get a good grade in the class. If you like a class that you never have to go to and just want to have Cramster as a teacher than take this professor. If not, AVOID AT ALL COST!

Take this guy for Linear Analysis if you can! I have to say that I don't truly understand linear, though I don't blame the teacher for this, just my laziness, yet I still got an A. He gives you 6 tests (including the final) none of which are cumulative. This is great because it means you'll never have to remember stuff from way far back in the quarter; you're only tested on a few sections here and there. He also drops one of these tests (including the final) which is extremely helpful. Just don't underestimate his tests and know how to do the problems in the assigned sections. Show up to class, especially the week before, and of, tests because he often tells you some of the exact questions that will be on the test.

during the first half of the course i hated this guy. he couldn't do the remedial math which made taking notes that much harder. after failing the first midterm and acing the second i got my shit together and ended up with a B in the class. overall i highly recommend this guy if you want an easy linear analysis teacher

Lewis presented the material well for the class. You have to have enough maturity to actually do the work and you will be rewarded for this. One thing that I would watch out for is that he does teach you the theory of the material in class. This means that you will actually have to work to get the answers and "study" the material. He doesn't collect the homework, but his tests come straight from the homework or are very similar to it. So, if you believe that you are not able to keep up in the class don't take him. Basically stated, if you are trying to blow off the class, you will fail it. However, if you think that you can keep up with the homework the class is really fun, easy and you will go away knowing a lot from this class.

Lewis...what to say, what to say. The man has a bizarre sense of humor, to say the least. "This is pretty bad...next to the Armenian genocide." Or when he was stuck on a problem: "I'd rather have my fly down than be up here right now." He also doesn't take kindly to people acting cluelessly when they're at the board. So when he assigns you a problem, be prepared to present it. Quizzes every other week, including the final, and none are cumulative. It's an open-book format, so it really wasn't that difficult. He never gave us a syllabus, so I really don't know the grading breakdown. Just go to class, try not to be bored, and you'll do fine.
