I took this class because I love psychology and I had free elective units. Don was extremely funny and kept me engaged the entire time. I loved going to his class. The midterms and final are very well written and not hard to do well on. He ended up curving the final grades to the point where i went from a 90% to a 95%. I am signing up for every class he teaches now.

I thought he was very fair in his grading. He is the best teacher I have ever had, so far. His test are very comprehensive, but fair. If you read the book and review his lecture its an easy class. The tests are an equal balance of both. He is very funny and you never have a dull moment.

Don Ryujin is awesome. He is so funny; there's never a dull moment. His lectures were pretty easy to understand. He gave a lot of examples that allowed me to better understand the material. I didn't care what grade I would get in his class; I felt lucky I got him. He gave me a very good impression of cal poly; this is what all cal poly teachers should be like.

Ryujin is an awesome lecturer, although he talked a lot about his life and some problems he faced being Asian, his stories and stuff were really kinda tight. I never really got into Psychology like a lot of people did in this class, but I still liked attending his class. Lecture is held in a huge auditorium with about 500 students, so taking the midterms gets a little cramped, but its fine. 3 midterms, a short term paper, and a final. Nothing more than you should expect, nothing less. Take the class, try to have fun, but most importantly get it done with. Oh, and the 15 minute breaks in between the lectures make a great time to escape and get some grub. Bring a notepad to draw on also.

>>>>>>>>>> TO EVERYONE OUT THERE Don Ryujin is clearly one of the best teachers you'll ever find at Cal Poly SLO. He's funny, a big motivator, and very informative. Literally, the guy knows his stuff. You might say that he's bias on certain subjects, HOWEVER, if you take the time to understand why he says it that way, you could accept his lecture instead of agreeing with it. The class consisted of 3 tests (40 multiple-choices and 4 short answers), and one Behavior Modification Project. I will only state this: if you want to take a class where you'll gain something out of it, remember some of his memorable lectures, and, most of all, learn more about YOURSELF (Self-Acutalization)...this is the class for you. I can promise that the majority of you will NEVER regret taking this class.

Don is seriously a wonderful teacher. He cares for each of his students. He makes sure they clearly understand the material and presents it in an easy way to remember. His lectures well...they're just one of a kind. Non-stop laughing. His tests are ok. There were always like 5 multiple choice questions (out of 40) that made you say "wtf." I always seemed to miss those 5, but did well on the essays (which were from his notes). I worked pretty hard and ended up with an A. If you don't mind putting in effort, I'd recommend this class. To all the people who understand this.. CHOCOLATE CHIP COOKIE!! Hahahaha

I took Don during Summer Institute 2006, and Don is one of the best teachers I have ever had! He's a very humble guy, and he didn't get a bunch of teaching awards for nothing. He presents in a very humourous fashion, and if you're paying attention, it's a fun class. Over the 3 weeks, we had a test every monday, and most of the material was on the lectures. They are worth 60 points: 40 from 40 m/c questions and 20 from 4 short essay questions. He speaks really quietly, so get a seat up front for the full experience. Finally, there was no homework. If you can get a chance to take Don, I highly reccommend it!

Don is a wonderful teacher. I think his lectures are interesting and funny. I don't remember ever being bored. He covers almost everything you will need for tests and tons of other interesting things. Psychology, like anything, can seem awful if you have a bad teacher. Don makes it really interesting though. The only downside to him is that sometimes he speaks softly, but he may not notice that he's doing this. Depending on the room you're in you may not need to worry about this. Good luck at Cal Poly.

I took this course during Summer Institute. Don is the best teacher i have had so far. He is clear and precise. I am a visual learner, so his teaching techniques make it easy for me to remember the material. About half of the test, which is multiple choice, consist on the lecture and the rest is on the textbook, the other half consists of short answer essays, which i can pretty much guarantee you that 99.99 percent will be from lectures. He makes the class interesting with his cookie theory and star wars lectures. you cant get any better than Don!

I took Don's PSY 201 class for Summer Institute '06. Your grade will be based on 3 tests and a behavior modification project. Definitely take his class if you can. Don presents the material clearly and makes every lecture both fun and informative. Believe me, you'll miss his class after it's over (I know I do!). Someone mentioned "Asian 101" in an earlier post. The original poster is a closed-minded asshole, period. If that person had taken the time to listen to what Don actually said, he/she would've understood where Don's coming from.

Ryujin\'s class was excellent. His lectures were entertaining; the tests were easy; and they will drop the lowest test grade of one of the 3 midterms or the final. I didn\'t take the final, but the midterms were easy and there are great online resources telling you exactly what to study.

A wonderful professor who has a lot of passion for psychology and a great sense of humor. It isn\'t easy to keep an auditorium of students (the largest class on campus last quarter) engaged, but he did it. I truly had a greater understanding of the human mind after taking this course. You have four exams which are equivalent to each other, with one of those exams being the final. Only the three highest scoring exams are counted in the final grade, which means you can completely skip the final exam (as I did). The exams are all multiple choice, which makes them much easier than the usual college course exam. Again, Don Ryujin is a fantastic professor, and the PSY 201 course is very rewarding.

If you\'re going to take PSY 201, take Ryujin! I\'m recommending this class to all my friends only because of him. He\'s my favorite professor at CP so far. He makes lectures fun and can get the whole class (over 500 students) laughing their heads off with his jokes. If I could take his class again, I would. The class itself isn\'t too bad. Just make sure to take notes in class & read the material. Don\'t procrastinate until the last minute to study for the midterm. The online class page for this class is very helpful, USE IT. Make sure to eat breakfast before this class because there\'s security guards in the front that won\'t let you in until you finish your drink or food.

Ryujin is a joke.. He is totally sexist against men because I guess he feels obligated to be? Everything he lectured was common sense, and I really didn\'t learn one thing from him. Really ironic that he tells the class how long distance relationships will NEVER work, when he himself admits that he had one with his current wife..... With the class, I didn\'t even buy the book and I got a B.. Pretty basic, just study the key terms online before the exam. My advice would be to take Kinesiology 250 (Healthy Living) instead of this class to fulfill the GE requirement.

Dr. Ryujin was a great lecturer, he was funny and informative. He seemed like a really nice guy. Since he didn\'t make up our tests or do anything else besides lecture then I don\'t really have much else to evaluate him on. I would take him again though.

Dr. Ryujin is a talented professor. His lectures are very engaging and interesting. He makes the material really relatable to the students, such as when he discusses romantic relationships and depression in college. There are three midterms, a short paper, and an optional final. NO HOMEWORK OR OTHER OUTSIDE ACTIVITIES! if you are satisfied with your grade, you do not have to take the final, for he throws out your lowest score out of the four exams. Again, the class was enjoyable and pretty easy if you utilize the amazing course website.

Don is an amazingly inspirational teacher and will tell you things how they are. I personally didn't enjoy the material whatsoever but the stories he told along with the applications of the material were intriguing. Nonetheless it was one of the hardest B's that I've ever worked for in my entire life. The readings were rather long (and often difficult) and sometimes it was hard to retain the information. I took this class during summer so there were only 58 people. However, we were putting in about 11 hours each week which proved to be very demanding. The only thing that I can suggest is that you sit at the front, pay close attention to what he's saying because his voice is slightly impaired, read the book, and memorize all of the diagrams and important studies in the lecture notes to the best of your ability. Good luck.

Honestly, Dr. Ryujin is an amazing professor. He is very helpful, understanding, patient, hilarious educated professor that will not only teach the material, but help you grow as a person as well. I truly feel like he cares for his students. His way of teaching is very helpful, it must be his psychology background of course. The way he presents everything is very simple and actually engages you and makes you pay attention. Very interesting, and cool professor. I highly recommend him. He's very clear and as long as you do what he says, you will earn a good grade. Fun class, definitely recommend him!

The funniest class and teacher I have ever had in school. Always a fun time. The topics he talks about in class are relevant to everyday life. There are 3 tests (one of which is the final). He makes the first test 20% of your grade and the next 2 30% so you can get used to them. The tests consist of 40 multiple choice questions and short answers. The tests are about 50-50 in class material and textbook material. If you do not read from the textbook you won't get better than a C+. There's also a B-Mod project that is very easy and I was able to finish the paper the day before it was due. Definitely recommend, especially over the other 500 person Psych 201 class.

Ryujin is a very guy and he definitely knows how to throw humor in to make the class remember certain terms. However i found that most of his recitations didnt really have that much to do with the tests. He would always say, i promise that this will be on the test, and then you would go take the test and there would be one question. He does make a decent effort in trying to get his students to pass the class, he always said that if yo0u were having trouble go see him and he would give you a tutor. Overall i wouldnt reccomend psy 202 to anyone unless its a required course, but if you do decide to take it i would reccomend another teacher for recitation, probably slem since he is the one who made up the tests

Here's the skinny on PSY 202. I didn't find it to be that exciting of a course but that's just my opinion. It's a lot of technical and scientific jargon for a course that studies people. The text is rather wordy and not exciting to read. Some parts of the course are interesting- I enjoyed the stuff on emotion, depression, the disorders, some stuff on the brain- but they really need to modernize the course and get a better text. You have to attend all lectures, recitations and read the text to do really well in this course. The multiple choice tests are pretty tough. With every test comes quite a few questionable questions. Some of them were either unfair, poorly worded, or didn't cover valid material. You really need to study your butt off for these things. The recitation kinda helped with the tests also. Don, on the other hand, had a great lecturing style. I always like his lectures just a little bit more than the others. He really could get the place laughing and had an upbeat style about him. I really think that he should do ALL the lecturing in the course and let the others just teach recitation. It was a cool GE, but Psych is not for me.

Overall the class was easy...it was a wierd setup though...different teachers lecture everyday. My only word of advice...WATCH OUT FOR THE TESTS!!!! The tests are written by Dr. Gary Laver!!! He writes the most ambiguous tests i've ever seen. I studied my ass off for this class and when it came time to tests i knew the answers but the choices weren't on the test!!!

When this guy lectures you come away with more trivia facts than Psych material. I think that's actually a good thing for an introductory psych course. His lectures were spirited and upbeat compared to the other prof's lectures. And those theatre seats are much more comfortable than classroom desks. Also, this course is EXTREMELY organized. The web page is great and recitations help your grade. TAKE THIS COURSE IF YOU WANT A BEARABLE GE!!

If you are interested in human behavior, then this is the class for you. The exams are written by Dr. Slem, whom I'm told is much better than the previous test writer. I really recommend this class because it is filled with useful information, and it is taught by great professors.

However, the lectures by Ryujin were fun and informative. The way he expresses the material makes it easy to remember, like the gym workout (You'll find out when you take the class). The tests and paper were not onerous as they could have easily been, and the class was mostly enjoyable. It was also easy enough to make going only semi-required. This class informed me much more than I had hoped into Psychology, which was excellent. The only other thing to say is find a good recitation prof - they grade you.

This guy was awesome. I took 202 which is a 500 person lecture taught by about 6 different people. Ryujin was the main guy and probably did about 6/18 lectures (I wish he had done them all). He is hilarious, a very captivating speaker that kept my attention for the full 1.5 hours every time he lectured, and he knows his stuff (he never uses lecture notes)... Grading was 3 exams, all equally weighted, 1 paper, and a recitation grade. Take this class with Ryujin, you will not be disappointed.

Don has an attitude different from a lot of professors. He teaches, and adds anecdotes along with the teachings. He shows videos of the lessons learned. And not to mention he goes over EVERYTHING needed for the test. I had a class of 30 but the grading policy was very easy, and don't fail a test, because it'll make you behind. The homework load was simple, because it was mainly reading chapters. You can actually skim or read the chapters, because half of the test is on the text. I am glad i had Ryujin because i heard horrifying stories of Psy 202 and it turned out to be untrue. Don has really good mnemonic devices to help you learn the material easy, because its a lot of material to learn.

It's only natural that the head of the Psych department is the best Psych teacher, and Dr. Ryujin is indeed one of the best. In PSY 202 you take a lecture with 500+ students and several lecturers over the quarter, and a smaller, 30-student recitation section with one of the lecturers. Prof. Ryujin is funny, witty, enthusiastic, and passionate about his subject. He really makes psychology fun and you'll come away from the class learning much more than what the material teaches. If you're taking a PSY class I definitely recommend Ryujin or Slem; avoid King and Ryan.

He's a rockstar, like Schoonover, but in a more subtle and quiet way. One of the most well attended large size lecture classes I've taken, which speaks for itself. Most classes have a take-home message relative to RL. Something about managing your relationship with the bf/gf or parents' expectations. Good personal stories sprinkled in, too. Testing is multiple choice from both the book and lecture. I took notes, reviewed them, and read the assigned reading once through. I didn't find the tests at all hard. If you don't test well on multiple choice, though, be warned.

Basically, he is full of canned jokes that would make middle-schoolers (and apparently most cal poly freshman) laugh their hearts out. Personally I found his humor obnoxious and lame. Also take away his humor and he teaches nothing, and is not particularly bright. Bottom line if you usually agree with most people take him cause I won't deny I'm very different from most. Also, my girlfriend had his class the year before me so we found out all his jokes were the exact same and his "drawing mistakes" that would randomly end up looking like boobs or something were also staged. Lastly, he is (in my personal opinion) a total crowd pleaser. For example: he will spend a good portion of almost every lecture whining about there not being enough work done in psychology on emotions while he has a PhD and has been in the field 10+ and that all he will ever tell you. Cause he is just so smart and right.

I had Ryujin for my discussion leader for PSY 202. For the class (400 student lecture in Spanos) there were 2 midterms and a final, all noncumulative. Don gave the discussion groups (about 40 students) an hour long lecture once a week clarifying what had been done in the lectures in Spanos, additional information, and study guides for the tests. He curved the tests and took out questions not covered in the study guide which was nice. Class was interesting- he's a great lecturer. He also rounds grades up if you do the extra credit!

Lectures weren't always dry, especially when Ryujin was lecturing. This class is actually very hard to earn an A in. But definitely worth it. I had to invest a lot of time studying and reading the textbook, which is extremely dense. The only way to pass the tests is with the readings. Do the online flashcards and quizzes, super helpful! In his discussion section he gives quizzes after each midterm and you MUST attend his discussion section it is the only way to get a good grade on the quiz, even though the questions are super easy but its stuff you only know from being there. Overall great guy and even rounds grades! Ended up with an A-

The (400 student) lecture can get a bit dry, but overall PSY 202 was a surprisingly interesting class. I did zero reading and still ended up with a B.

Don Ryujin had the most engaging and entertaining lectures I've had from any professor at Cal Poly so far. His anecdotes were not only relevant, they were interesting stories about his life, and they often related to some greater purpose or deeper meaning. You can tell just how passionate this man is about teaching just from listening to his lectures. He taught PSY 202 along with a couple of less entertaining professors such as Gary Laver and Kathy Ryan, whose lectures were more just a presentation of information from the text. This class required you write a paper that was really easy to write and easy to get an A on. I never read the text book, instead, to study I always just did the quizzes on the online syllabus and it was enough to get a B in the class (maybe even an A if I had written my paper on time and didn't lose a lot of the points; my mistake, though). Pay attention to all of the lectures from this class and try not to miss them because they do come up on the test. For me, it was not hard to pay attention to Ryujin. Overall, to do well just show up to class and listen.

Don is an amazing professor that is really good at connecting with the students during his lectures. He is also very knowledgeable and relatable, and his lectures are often the most important and most relevant to your life. He is very easy to pay attention to as well. I also had him for discussion. He is equally as genial, but he talks less psychology and more "how to do well on the exam in terms of blah blah blah material." So it isn't really as much of a discussion as a study session, though you can ask him questions during class if you so desire. But the way he helps you remember the material in discussion is really good for the exam, so be sure to attend and get all the tips you can (it will totally save you having to read too much in the book). Pair his study guides with the online resources and you should do pretty well (above average for sure) on all the exams. Don't forget about the writing assignment; it's pretty chill for the most part but Laver always grades them so it doesn't matter who your discussion professor is in terms of the writing assignment. But take any class you can with Don, he is really a very solid professor.

I really enjoyed Don's (he likes to be called Don) approach to the class. Instead of strictly lecturing about the reading material, he added a lot of interesting information from his other classes, research projects, life stories, etc. He is the most engaging lecturer I have ever had. This is especially interesting because he is not the loudest or most dynamic lecturer I've ever had. It is just his quiet confidence, connection to students, and passion about our learning (learning for personal development, not just course work) that makes him so enjoyable. I believe that he cares more for his students and looks out for us more than most other professors. He put a lot of effort into giving advice related to our course studies that would help us build relationships (friends and romantic partners) and develop ourselves. Accordingly, he does a great job of breaking the student teacher barrier in and out of class... you might come to think of him as more of a friend than professor, I do. SO you have to take one of his classes if you can, it could really help you learn to develop yourself. Also, if you're looking to see how your grade will turn out, I think you will be just fine in Don's class too. In the personality class I took, he handed out question sheets days before the exam for us to study. These sheets did a great job of covering the material to be found on the test. The tests will be the only basis for your class grade (to be fair, this is hard for some people). The tests are multiple choice and short answer. If you review these sheets and study with at least one other person you will do GREAT on the tests. I should emphasize again, study with other people. It will be a great help to you (again for the class and for personal development). When I studied with other people, a lot of interesting things came up. So, take his class(es), and GOOD LUCK!

However, he tries to keep it interesting with relevant studies that we would appreciate. He curves his exams because he knows that not all test questions are fair, which helps. He also has you do a presentation of a psych study to present in front of the class, but he also acknowledges that some students are terrified of speaking in front of their peers so he gives those students the opportunity to write a paper about a study instead. He has been teaching at Poly forever and by doing so has become a great professor that has put a lot of thought into his class.

Don is a great professor. His lectures are very interesting and the workload is very fair. He teaches many lessons that go beyond what I would learn from a typical class. I learned things that I have and will continue to apply to life. Taking his Personality class was literally life changing. Don, if you are reading this, thank you.

Best professor I have had at Cal Poly! His lectures were almost therapeutic for me. There were days that his lectures made me feel so much better about my life and where I stood within my own major. I highly recommend taking him. His lectures can easily be applied to your life. He makes you think about things in a different way and he is also a funny guy just to talk to. I wish I could take another class with him because honestly this class will be the one I remember for years to come. Also because he is aware that we aren't all made of money he picked an old edition of a textbook that was super affordable- mine was 20 bucks on amazon. I honestly really respect this guy and enjoy him. He does everything he can to not be a biased grader. There are essay questions on the test (as long as you do his study guide you'll do great) and he grades them based on your empl ID number so that he doesn't give you a biased grade based off of you as a person. TAKE HIM if you can! You won't regret it!

Good luck teaching yourself the material. He says his tests are difficult and that's because he doesn't teach you what's on them. What a frustrating class. He let us out early all the time and then 75% of the material he tests on is from the book. Waste of your money and time. He was funny and seemed like a nice person, but choose a different prof.

Got recommended this class by a friend who said this was his favorite class of all time. Did not disappoint. Ryujin's teaching style was different in that he does it via PowerPoint slides, but he won't give out all the info on the Slides, and he doesn't post the slides on PolyLearn. So everything you need to know is in what he explains during lecture (attending lecture is VERY important), and his explanations are really clear. His examples are on point and memorable, so you'll be able to remember them for the midterms. Make sure you take notes on everything he's saying as you'll probably need to use all that info on the short-answer part of the midterms. All the content and material was super interesting and you get to take lots of personality tests (if you're a good partner for a relationship, what parts of your personality are high/low, are you introverted/extroverted) that help you learn more about yourself and are fun (all tests are optional). The presentation was really easy and had a basic format to follow, so it's really nothing to stress about. He gives you the option to write a paper instead of do a presentation, but I highly recommend the presentation as it is quick and easy to do. Would highly recommend Ryujin for Personality, because I actually learned a lot and the material was super interesting and straight forward.

Don's a great guy, he's empathetic, he's genuine, and he certainly knows how to make a lecture entertaining with memorable examples. However, the examples often drift into tangents which become the focus of the lecture. I often left his class with an incomplete understanding, and I don't feel he answered the question of what we ought to take home from his lectures and ultimately the class. Expect to read the textbook many times beforehand to link the tangents to the applicable theories. A lot of people prefer his style, I don't; personal preference. Don't get me wrong Ryujin is definitely in the upper echelons both on Polyratings and as a professor, but some of the reviews border on flattery, so read all the reviews with a grain of salt.
