Reviews of professor Wang-Yong Yang

Rating: 2.0/5, difficulty: 5.0/5
Professor teaches a flipped classroom, you have to learn all the material on your own. Youtube is way more helpful than lectures. Yes he does give extra credit but it is only a point or two so it is not that helpful. He does not respond to emails. If you want an answer you have to go to his office. He is not encouraging or positive at all.

save yourself and go with anyone else. he teaches a "flipped classroom" which means the student has to be the professor as well. he is rude to students if they get something wrong and likes to point out if something is "gen chem knowledge" if someone gets something wrong. overall the worst save yourself and your gpa

Organic chem is just going to be a really difficult class period. Despite having a ridiculous amount of work, I think this professor was the best option. He gave a bunch of extra credit, including bonus points on exams. Fair warning though: he does flipped classroom (lectures online outside of class). I would still take him again though for sure.

This class is very difficult in general. My main concern is the homework, the website he used when I took it was hard to use and took easy hours to complete which left no time to study. If he changes that later then I would take this class with him but that makes it so much harder.

Based off past reviews I was worried to take this professor. However, I was surprised to find the majority of the reviews wrong. He was always eager to help when I went to his office and very nice. He gave extra credit on both our exams. My only complaint would be that some times he did not explain things well. I would take him again for lab.

Even in my class, Dr. Yang seems to not be very popular. However, I found his class layout to work well for me (flipped class, learn material at home and practice problems in class). All of his tests and quizzes have extra credit. He is very understanding when missing a class for a good cause. He also answers emails better than any professor ever.

Dr. Yang is difficult, don't get me wrong, but that's the nature of Organic Chemistry. Trying your best and giving it your all will take you far. He's very gracious with extra credit and partial points, which can really boost test scores. Just make sure to aside time to watch video lectures and come to class prepared, and you'll do fine.

I wouldn't take him if I were you.

He's not the best at teaching. You're better off teaching the material to yourself since he doesn't really explain topics that well. He's a tough grader and he really doesn't prepare you for exams. He also sometimes give belittling remarks towards the class.
