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-
