Get used to hearing "it's very easy", and "its not hard, you just do this". He is not helpful at all if you want to talk about tests, spends 5 minutes going over a test...during his office hours. No study guides, takes a long time to give tests back. If possible take with another professor. Both tests are worded awkwardly the whole way through.

The class started of kind of easy but don't UNDERESTIMATE it because its a startz getting harder. So stay on top of it !! Test are okay i guess he'z not a bad teacher but I was slacking off. JD douglas and zhang and the book all say different things tht getz to be a little confusing!!

Try to avoid him if you can. His lecture is very unorganized and confusing. Only hope you get a good grade from his class is "pay attention" on what he is saying because textbook is very unorganized, annoying, and doesn't help you at all.

Worst teacher I have had. Can hardly speek english, has no teaching skill, and when he realizes that the class is confused he just talks louder. The avg. in the class is a D.

This class is not that difficult. Never went to class or studied, ever. Still got a C out of the class just by doing the homework and taking the tests.

Zhang is probably one of my least favorable instructors ever. He speaks with an accent and talks way too fast to understand the material at a normal pace. The material is not too hard, he just words it very badly in lecture. Tests are extremely difficult, his online review helped me maybe 10%. The rest I learned on my own/tutoring center.

He tries, but it is super hard to understand him. He always says "it's easy" and answers his own questions. He also still doesn't explain things very well when you ask questions in class. I'm generally good at math, but this class was difficult

Zhang has a very thick accent that is hard to understand at first. He is very intelligent and loves teaching. He gets extremely into his lectures. Class attendance is not mandatory but showing up for class is better. I taught myself everything for the second midterm from the book. The whole class is fairly simple concepts.

George really isn't that great of a teacher. Class material is complex, and the homework assignments are extremely tedious and much harder than the test questions. If you do the review entirely you'll do fine. Gives you a cheat sheet for exams, put some review problems on there for help!

Zhang moves very quickly- he doesn't slow down, and doesn't check to see if anyone understands. His accent can be thick sometimes, and his handwriting is terrible. I learned more from the book than I did in his class. He's fine if you have experience in Stats, but for beginners, it's horrific. He has a lot of trouble answering questions clearly.

If you do not read the material before class you are going to have a tough time following what he says. The foundation for why we are studying what we are studying really isn't there and I had to go to Khan Academy to get further information. "It's easy", "It's common sense", are just a few of his regular phrases that don't do much for anyone.

If you show up to every class and pay attention, you can easily get a good grade. I stopped reading the book halfway through the quarter and still got all needed material. Does not understand student questions often and makes it more confusing when they are asked. I would not choose to deal with him more than this once.

George is an alright professor. His lecture pace is too fast but he ends class 20 mins early to ask him questions if you have any. The tests were harder than I ever expected. He does allow a sheet of notes which is nice, but I often found I didn't have what I needed for the exams. I've never taken stats before a I feel like I still don't know much.

Zhang's class was pretty easy throughout the first half of the quarter until the 2nd exam. The average score was 65% on his second exam... It was obvious that many people did not understand what was going on. His lectures are extremely fast and hard to understand. Course material wasn't easy on top of that so the class overall was pretty difficult.

One of the worst professors Ive ever had, just assumes that we all understand And jumps from subject to subject quickly. He isnt hard to understand sometimes. Class material is simple but the tests are pretty hard. You do get a sheet of notes. Hw is also an easy 100% if you go to the help sessions

Professor Zhang does not have a good grasp on class understanding. If you are confused during class, Zhang is mediocre at giving alternate explanations to student questions, let alone give any clarification. This class was one of the worst classes I have taken at Western.

If you have taken stats before, you have nothing to worry about. It'll be a little harder if you haven't but nothing crazy. The lectures are difficult to make it to, just summarize the practice exams on your note sheets and it should be an easy B, with the curve.

Zhangs lectures were pretty long and boring for me. Many is the assignment quizzes didnt have anything to do with his lecture at time either and the midterms and final wasnt much better either. Avoid if you can.

He is obviously very knowledgeable about the info but his presentation of it to students is pretty atrocious. Lecture slides are all over the place & missing info and is just not presented well at all.

The homework really gives you a false sense of security. The textbook and lectures are relatively easy to understand, and the weekly homework is almost ridiculously easy, but the exams really hit like a truck. If you start preparing early and do every single problem in the book, there's a good chance you'll get a B or higher, but it's hard.

The exams are hard, especially the final! The questions in the final took too much time given the time limit. Be aware that a couple of things not mentioned in the lectures will be tested. The HW is kinda similar to the exams, so you MUST thoroughly understand them to do well on the exams. BE SURE TO GET 100% ON ALL OF THE HW!

Professor Zhang is nice but my complaint is that the tests covered material that was never even mentioned. He has prerecorded lectures that I recommend watching throughout the week (

Prof. Zhang seems like a nice guy, but the class is rough because of the language barrier. The lectures are not the easiest to understand, and so I ended up teaching myself the majority of the material online. The HW are unlimited attempts and the 3 tests are online. Don't buy the required textbook either, it's not necessary.

Can't do morning classes, so I completed this course with a mix of the online lectures and the textbook. Lectures aren't great, he has an accent but it's perfectly understandable. 75% of my understanding came from the textbook. Unlimited attempts on quizzes, double-edged sword if you're lazy. Not the worst class? Got an 85 (curved to B).

Bad lecturer, regardless of his accent. He is roundabout and says the same thing over and over again, and for some reason once a class would talk about a concept and then say it doesn't matter and we aren't going to be using it. I learned nothing in this class, even as someone who normally likes school and tries.

had an A- before the final, got 68% on the final and due to the kind of curve he had i still ended up with an A- in the class (top 10% of the class). he will take a long time to respond to emails, zoom lectures are just him playing old youtube videos, and over explains all the wrong things. would recommend a different prof. unless you can selfstudy
