Went to class twice and just taught myself everything based on the slides. Honestly the class is definitely easier than 10a and he gives a generous curve (even tho he doesn't put it on the syllabus). Midterms were easy and final was harder but fair. Definitely not a great lecturer so honestly just be good at teaching yourself.

The professor seems very nice but the lectures weren't that helpful and were very concept based. The midterms were fair but the final was very hard so there was a decent curve. The class gets harder/easier a few times but just make sure to do all the practice problems/tests. For sure was difficult but not the worst, a little harder than 10A.

Not the best professor, but definitely not the worst. You have to teach yourself the material. Exams were very similar to previous exam questions. Slides and lectures were useless. Midterms were very straightforward. Generous curves because everyone usually fails the final.

he is fine, lectures are not super helpful however he is more helpful than hartman if you had him for 10a. i mean standardized course, curved about 8% bc our final average was a 58%

Grading: 4 Modules 20%, 2 Midterms 20% each, Final 40% Don't bother going to lecture. slides are useless. You will have to teach yourself. The good news is he gives a lot of practice problems and provides past exams. I used them to learn the material. DO THE PRACTICE QUESTIONS. The exams were similar to the practice questions. Class is fair IMO.

Econ100B is a very standardized course, and a lot of practice is helpful for you to study. You gonna miss him once you take other ECON classes immediately. Prof.Qin made this hard course manageable to learn. I think he is largely underrated somehow right now.

Tests are hard but the class is manageable. I had a hard time focusing in his lectures, but once I switched to watching his lecture videos you can see he goes through the topics and each example very step-by-step which I found helpful. Just keep on top of the topics and you'll be fine.

One of the worst professors I have had at UCSB. All the material must be learned on your own and lectures are useless. Does not care about his students in the slightest.

made 100b so hard for no reason. lectures unhelpful. midterms way too difficult. gonna have to complain for a curve hopefully

Qin seems like a good guy, but as a professor he is not hitting the mark. I mainly used CLAS rather than the lectures to actually teach me the material. The practice final (only one was given) was a little strange with the wording of their questions but the actual final this quarter was HORRENDOUS. Get ready for lots of independent learning

Went to class 3 times total, prof is adorable but the tests were lowk hard

Doesn't know the material or how to teach. Honestly just a useless class taught with no help from the prof. or TAs. Nobody can understand why the Econ dpt consistently provides awful, awful classes with some of the worst professors one could imagine. Don't worry if you're in the major and have to take it though, you'll never use this material again

Dear god this class was hard. I struggled with lecture, he seems like a sweet old man, but it's so hard to learn in his class. It is a continuation of 10A and only is based on two midterms and a final. Average for final was horrible and they almost didn't curve it until everyone complained. If you have to take this good luck.

Our final exam was worth 50% of our grade and the average was 14/25. With this in mind he does not curve the final or the overall grade of the course. In preparation for this final I completed every practice problem provided for the exam however the final was incredibly different than what he gave us to practice. Do not take his course.

Had a B going into the final. Ended with a D. I could have prepared better but I found the class difficult as I had two other upper divisions to take with it. My advice is spend more time than you feel necessary on practice and remember every fact possible.

The fact that its split 25/25/50 for midterm midterm final is already brutal, but on top of that you could do really well on both midterms like I did, but get screwed over on the final because of how much stuff there is. By the way not curving the final when the average was basically failing is absurd, so now the class is sitting an average of a C

Terrible class. The median of the final is 14/25. The final is worth 50%. No curve.

I think most comments here are unfair to Professor Qin. His explanation of the material is very clear and the tests are straightforward. As long as you listen carefully during lectures and do the practice, it is not hard to get a good grade in the class. Also, if you ask him questions after class, you will find that he is very kind and helpful.

Lectures are muddled and confusing. It is currently finals week and the only things in the grade are 6 homeworks and a midterm. This midterm the average was a 54 and he has said nothing about curving our grades, and most students are worried about failing the class. The professor has only offered to drop a single homework grade to "accomodate."

Cheng is a picky grader. His explanations of concepts taught in class are subpar. The only positive of taking his class is that he curves the grades. If you get stuck having to enroll in his class, good luck. Otherwise, I suggest taking a different elective.

Idk how he is in person, but online Qin is an amazing professor. Lectures seem boring at first but you get used to them. Explains concepts very clearly and his practice problems are very useful for studying for the exams. I highly encourage everyone to go to TAs office hours as they are very helpful. Put in the work and youll get an A or an A-

Stay away from this professor at all costs. He is the most confusing professor I've ever had in 4 years. take any other class if possible , game theory was way easier because at least the textbook was good. this textbook doesn't line up with material at all.

Should not be a professor. Lectures are so scattered and he bounces around everywhere. Taken during zoom and he recorded the lectures on something from the 1970s or earlier. Where does his massive salary go? id propose that it isnt towards his computer or microphone. or becoming a good professor. Just one broke mans humble opinion.

Material covered is very very difficult. Doing the HW requires a fair amount of guesswork. Exams are somewhat similar to the HW problems but still hard and he's very nice if you approach him one-on-one. The class is about asymmetric information, lying, and cheating games. It's really cool!
