Absolutely awful. Very difficult to understand what he is saying, and he'll fly through problems and skip steps, which makes the material very hard to understand. Find a different prof if you can.

What I only want to say is : DONT TAKE HIS CLASS

His accent takes a few lecture to get used to. He expects student to be fairly competent going in, so unless your algebra/ trig skills are top noche, his work will seem unclear. He care about whether or not the student learn the material, not just there because he has to be.

He will occasionally laugh at the class because he knows knows very few students are actually following his proof. That being said, the tests tend to be straight forward, just don't expect to be babied.

Bing is incredibly smart, but not a good professor. He knows this, and is constantly working to make himself a better teacher. Unfortunately, that's not the same as being a good professor. If you have the choice between Bing and another prof, take the other.

Wang has a tough accent for sure. He tends to do the proofs a lot and then get confused in his only explanations. It doesn't mean that he doesn't understand the material well it's just difficult to him to explain it. He uses half the lecture to review and half the lecture to cover new stuff. If you don't want to teach yourself, don't take his class

It is clear that he tries very hard to be a good teacher and make his points understandable but, but the straight fact is that he is not. I'm sure in a few years of teaching he will be much better but a this point, ignoring the accent, his lectures are VERY difficult to follow. He seems to make things more complicated than necessary quite often.

Hard to understand, too high expectations of students coming into the class

Bing Wang sent out an email early this week saying that math 222 is a hard course and it is not his problem if we cant follow. I learned absolutely nothing by going to lecture, but my TA is super helpful so I have a decent grade in that class. AVOID him if u can! Math 222 is a hard class that's why we need to have a good professor.

I think he tried he is just very difficult to understand and I wish I would have gotten a professor that made more sense to my style.

basically, he makes everything so confusing. i knew partial fractions before i took the class and i can easily say that his explanation was just so horrible that i felt really bad for the people that were learning partial fractions. you have no idea what he is trying to talk about. but i could tell he was improving towards end.

No clarity in explanations, no idea how a microphone works, jumped from topic to topic in no sensible order, exams were fairly ridiculous... I strongly recommend any other professor

This is the second time I’ve taken this class. Lectures were very confusing. I was lucky I knew most things already from before. I found his accent to be understandable, lecture room was awful. No way to check your grade at all. This class will depend a lot on the luck of the draw with your TA. I would take the class with a different professor.

He isn't a good professor. I know he tries, but he spends the entire lecture doing proofs that we are never going to use. He reads right out of the poorly written textbook. For your grades sake find a different professor.

Goes through material in a confusing way and explains things in theory. I found the test to not be too bad though.

Lectures were so confusing, disorganized, and full of proofs and unhelpful examples that I stopped going. His accent was strong but understandable. Tests weren't too difficult, but grading was unforgiving. My TA was terrible, and I only did well by reading the textbook and working with friends. I would highly recommend avoiding Bing at all costs.

Bing Wang definitely knows his stuff, he just doesn't know how to teach. Homework rarely ever relates to lecture. Lecture itself is pretty difficult to follow because it's all useless proofs. If you get a good TA, you might have a chance, otherwise you better teach yourself. But watch out for that final, he gives you stuff you've never seen before.

Bing is very intelligent, however he is not the world's greatest professor. If you put in the work, you will do fine, however, if you are only somewhat familiar with the material, his tests will consume you. He will give hints, but you have to know what you are doing. So if you just want a good grade with the least amount of work, he is not for u

This course should be very easy. The concepts are fairly simple and straight forward and not at all more difficult than previous calculus classes. With this said, Bing Wang makes this class difficult with very poor teaching and a final that was absolutely ridiculous. Highly recommend avoiding him and getting a different professor.

This guy. I really dislike the way he did his class. It was much much harder to get an A in his class versus the other 234 professors. He was understandable if you tried, but he read straight from the horrible book and spent the majority of the class doing proofs that were impossible to follow. I hated this class and every second, and I love math.

Bing Wang is very difficult to understand. Not an overly difficult class overall but was made much harder because the class basically had to decipher everything he did. He also made the final extremely difficult (average was around 45%) because he felt the two midterms had been to easy.

What he talked in lecture rarely relates to tons of homework .

Wang is bad, but not as bad as the other reviews suggest. He chooses the most difficult and obscure questions to put on tests and I think he actually likes making students do poorly. He makes sure the curve is no better than a BC which is brutal and unfair for a class like 340. To do well, you must master every textbook problem.

First off he curved the class to a 2.3, which is terrible. I had some trouble understanding him, and he assumes a lot of knowledge that I didn't have.

Bing Wang is difficult to understand, though the accent isn't as terrible as his teaching. His few examples that actually help you learn the material do little to help with his exams. Not a well structured course and not the professor to take it with.

His English isn't that great and he has an accent so it is hard to follow his explanations in class. His actual work on the board is clear at least. Tests were very difficult.

Bing Wang is a pretty average math professor. His accent was easy to understand. He spends the entire class writing on the board and there is very little room for participation. He will answer questions, however, and this teaching style is common for math classes. He receives more criticism than he deserves but certainly isn't a great professor.

Nice guy but hard professor. Makes class and subject hard. Tests have so much on them that he never teaches.
