Reviews of professor Yun Yang

Rating: 2.0/5, difficulty: 4.0/5
nice person, but not a great teacher. I wouldn't recommend his class if you're trying to learn the material, but his grading procedure is fairly generous and there was a massive curve at the end of our class.

He is a really friendly guy, and is a fair/generous grader. However, the course itself was taught in a manner more geared towards those with a background in mathematical statistics which made lectures kind of hard to follow.

Well he is a nice guy and curves final grades nicely even though I still don't know what i got on my final. Lectures are very unhelpful as most of the time it's just confusing formulas with little explanation and not enough practice problems online. Also 2 exams (70%) and 5 homeworks (30%) being your entire grade is not a great idea.

Easy homework, typical lectures. There are only three exams (2 midterms and one final). The 2 midterms he gave were a piece of cake, but when the final came, it was shockingly impossible to solve. I was lucky to have it curved, but if you have Yang, study beyond your limits. You are going to need it. Don't let your guard down in his class.

He has got to be the worst professor I've ever had at U of I. This class is insanely difficult, the lecture slides and homework do nothing to help you prepare for the exams. He is also very unhelpful, half of the time he's not even in his office during his office hour (I went three times and he was there once). DO NOT TAKE HIS CLASSES!

The WORST. Tons of homework, hard exams, and sometimes impossible quizzes. Really hard grader. Always lectured quietly at the chalkboard while copying from the textbook almost word for word. No explanations. Skipped steps in proofs and problems. DO NOT take his classes or else you'll be doing your job AND his job.

If it is possible to give 0 to this prof I will definitely do that. Hard homework and exams and lectures doesnt help. What he taught in lectures are logics and proof, which is hard to understand and apply in solving problems.

Were supposed to have 7 homeworks, ended up having 4 homeworks, including only 1 after the midterm in Early March. Never once explained something that he wrote down, no class forum to ask questions, and no other supplemental material that resembled the class in any way. Having 5 total assignments and exams determine your grade is not smart.
