This class was difficult. Significantly harder than 11 imo. The lectures are not helpful. Midterm was easy but the final was significantly harder. Midterm av was like 80 and final av was like 64%. Make sure you study or hire a tutor for this class. Midterm 30% and Final 70%.

Idk, this class just has the midterm and final and that's it. The midterm was easy compared to the final, the avg was like a 78%, while the final average was like a 60%. The entire class grade is based on ranking and only 25% of the class gets A- or better which is kinda tuff. Just be prepared to put in the work the week leading up to his tests and you'll be fine. At least he has a sense of humor at times!

A fair class...Contents can be a bit confusing if you don't go to the lectures at all or they are completely new to you because there is more width than depth in this course. But just because of that, once you are able to comprehend the core concepts, it would be an fairly easy course.

It was so easy that I got A+ even though I did not go to any of his lectures after the midterm. It's extremely helpful if you take Stats 10 before taking this class.

Got an A- but would definitely not recommend zhipeng. His notes in class are basically word for word from the notes that he posts. He does not go over many examples in class and a lot of the notes are just long proofs for things that really dont matter. He is hard to understand (accent) and often spells things wrong when he writes them on the board. I never went to him one on one so i can't comment on that. He tries his best to answer questions and you can tell he cares about the students he just lacks the ability to convey things properly and effectively. He just writes stuff on the board and doesnt explain how you would use something or what it is for. Basically says use this and plug in this and you get answer. You won't learn anything. Midterm was easy final was hard, He uses the department curve 25% A 35% B 25% C everyone else D/F. So it is possible to get screwed by the curve. Don't take this class and avoid a ton of stress.

Good class overall. Need textbook for HWs and exams. Selling book for $80 (new costs $120). Email: *************

I found Liao to be a great professor overall. He posts concise lecture notes and gives fair tests. There isn't any homework (although he assigns homework questions for your benefit), and your grade is 40% midterm and 60% final. The midterm was super straightforward, but the final was a bit harder, since we needed a proper distribution for the curve. I am not a straight A student, and I found his class very enjoyable. I would recommend him.

great econ professor in econ department. You can learn a lot from the class. Selling textbook for econ41

He is a good professor. His class is clear and straightforward. he loves to answer your questions at any time. You will always get the points. His final is harder than midterm. However, I did final better than Midterm. I think it's not hard like they said if u work hard. Really a good professor u should take.
