Easy to get an A, but not easy to understand him

Possibly the worst professor ever. Had to drop his class not because I couldn't understad hime but because he was so unprepared and made so many mistakes. It was almost like we were teaching him!

So far I am taking his sta 282 class and so already I think he is horrible. He can't speak english.

This teacher makes no sense and only confuses you more when you ask for help.

very hard to hear and understand... class isnt too bad though, gets very annoyed when you cant understand him, but he doesnt speak good english...

Does not speak good English at all, we spend half of class asking each other what he just said. The exams are on-line before the test so you can study that and pass the test. He doesn't collect all homework either.

Terrible. He explains things well in class and the homework is easy, but nothing on exams is related to class work at all! No clue as to how to communicate with students and he often came to class without any idea how to do the examples he wants to show us!! By the book and study on your own!

AVOID AT ALL COSTS!!! He doesn't speak english, so he doesn't understand when he is asked a question and it's hard trying to understand him.

AVOID! This man is possibly the WORST teacher that I have ever encountered. I am an A student, so I am credible, and I am majoring in math. This man Makes you teach yourself because he has no idea how to teach. AVOID and save yourself the swift kick in your grade that he may provide

Horrible teacher, and you cant understand him.

Well...he sucks his grader sucks, the language barrier is ridiculous. If you memorize the pratice exams you should pass class I got B+. He doesn't help, you teach yourself. Watch out for his words and how you interpret them, I know I had to. Horrible guy but easy class!

Shouldn't have been that hard of a class, but I struggled. Not very helpful, so hard to understand, and his grader sucks

Like everyone says, the most terrible teacher of all time. I went to Central last year, failed his class. Im at Ferris now and im doing fine, but out of all of the teachers ive had, he is bar none the worst ever. Dont take him, no matter what, ever...

TERRABLE, SUCKS, STU..D, I hated this class this professor made me change my minor.TERRABLE, when things got tough, he SUCKED as a teacher. He never fully answers questions and never bothers to find other ways to explain things. If you get him for Business Calculus, you best hope you can get right on out.

Has no idea what he is teaching -- I have never been to a class where one of the students didnt have to correct him. The material he taught was easy, but he made it hard and confusing. To get a good grade, all I would say is read the book--teach yourself--and do the practice tests online.

Save yourself the touble by not taking this guy. He is terrible. He speaks very broken english so it makes his lectures very tough to follow. His notes are scattered and dont cover what the homework is on. All work is done online and can take forever to finish. He doesn't really care for the students, class is unorganized. Find someone else!

wow... this teacher is very horrible. He is a horrible teacher. It is very hard to understand what he is talking about, which makes it harder. Stupied mean , have no clue, most of the stuidents in the class know more than him, and keep correcting him in the class. STUPIED

Very difficult to understand. very rude when asking a question. doesn't give a direct or specific answer. recommend taking this class at a community college whereas professors will take time to explain.

Homework is online and is pretty easy. Exams are just like homework, but were very difficult for me. He is very very hard to understand, the class is very boring. He just takes notes for you to write down... I basically taught myself in this class, so I would not suggest taking it with him!

You will have to teach yourself.

TERRIBLE, Doesn't teach you anything. You have to teach yourself everything. Doesn't go over H.W. or explain anything during class and you have no clue/idea what's on the test... DO NOT TAKE HIM PERIOD!!!!!!!!!!

Incredibly hard to understand, you will HAVE to teach yourself. DO THE ONLINE HOMEWORK! It's a grade saver. Left the class learning absolutely nothing, and retained zip. Go to class though, there's in class quizzes that save your butt.

I have never failed a class in my life until this one. First of all the homework takes a minimum of 5-6 hours a week. You have to teach yourself everything. Honestly I do not understand how this man got a teaching degree. Save yourself and don't take this class.

May be the worst teacher at Central Michigan. Struggles with English, homework and teaching directly from online presentations. Terrible.

He has a hard accent to understand and he sometimes rambles off the topic and you might not know what he's talking about. Please don't take him for your own sake. Unless your good at math. If you aren't then don't take him. It's seriously brutal. Literally worst thing ever. Never would I take him again. Not even if there was a fire.

He is the worst math professor I've ever had. He is extremely difficult to understand, is not accessible to students for help, doesn't answer emails, and his lectures are the most pointless thing in the world. I only go to lectures because he has daily assignments at the end of class. His exams are easy as long as you do the homework.

Horrible teacher. Never failed a class until his class and he was the entire reason why I was put on academic suspension. Don't take this guy whatever you do.

LITERALLY THE WORST PROFESSOR AT CMU. I have never been so confused in my life in any of my other classes at Central. He brings handouts to class everyday, and I'm pretty sure this is the first time he actually looks at the handouts himself. Takes him 50 minutes to get through a 5 minute example. Absolutely HORRIBLE. Avoid at all costs!!!!

The only reason i would take his class again because it is so easy to me as i am very successful with math courses. If you have a hard time with math, STAY AWAY FROM PROF WANG. Nobody can understand a word he is saying. Going to class is completely pointless besides the fact that he threatens to take away participation pts. Horrible teacher.

If you do not want around 10 hours of homework each week, stay away from this professor. Very unhelpful and class is pointless, i taught myself everything. You will never be able to understand him while he is teaching. Somehow have a B+ but thats because i spend 10 hours a week doing hw for this class...

I took his online class. He does not communicate with anyone. He just tells you what to do and expects you to do it. He never offered help. His exams are hard and sometimes they barely touch examples that you went over. Do not take this class unless you want to teach yourself how to do things.

Doesnt respond to emails. Huge language barrier. Homework every week that can be easily done.

Dr. Wang is pretty decent for 580, but for 590 he was awful. This class made me want to cry. Honestly, good luck trying to figure out what's due each day because he doesn't even know.

Unhelpful: Provides no actual instruction; not one lecture, supplemental material or even an email asking students how they are faring. Inattentive: assignments for the week not released for work on time, sometimes not until after the assignment is pat due. Uncommunicative: does not respond to emails for days, a week, in one case a week & a half.

Stay away from Professor Wang. You will spend way too much time doing homework that he does not even know how to teach. Lectures take a long time and he spends almost 4 hours doing 2-5 in class questions and only ends up confusing the class more. Grading is not clear. There is no way to know your grade until the end. I would not recommend him.

This class was terrible overall. He expects you to put in 20+ hours of work for just this class alone. Very little help from the prof and the grading process is very unclear. You don't get your actual grade until the end of the term. Many students struggled with the online format, and the prof was inflexible with deadlines given circumstances.

I would try to avoid this teacher. His lectures are confusing and half the time he doesnt know what hes doing. Everyone in the class has no idea what he is talking about, but he grades pretty lienient which is a good thing because if he wasnt then everyone would fail.

Doesn't teach you how to do any of the calculations. Does not know how to respond to emails. He would log off in the middle of the course because he doesn't know how to solve the problem. You will not know your grade because nothing is in the grade book.

WORST prof ever! So unorganized, doesn't answer emails, no information for assignments. He never knows when an assignment is due and gives you very little time to complete hw. No grades or feedback. Group assignments but no way to get in touch with anyone if you're online and no information if you do class in person. Do not take!!!

I would not take stats with this professor. Teaches straight out of the textbook and does not actually show you how to do the problems. Multiple homework and quiz assignments each week that take a long time to complete. I don't feel like I learned anything in this class.

He talks so quiet that you literally can never hear him. He spends half the class figuring out what his own notes mean. He never responds to emails. Avoid at all costs.

Do not take a class with this professor. He talks so quietly you can barely hear him. All of his due dates on blackboard were at least 3-5 semesters old. You will not know what your grade is at all throughout the course. He had to relearn the material in class as he was teaching it, and frequently provided wrong answers to homework questions.

He did not seem familiar with the course material or required programs whatsoever. Homework was assigned before going over the concepts in class (or were never discussed at all). A lot of self-teaching and then adapting based on how he wants it, but there is extremely minimal feedback on assignments/exams. In-class activities nearly every class.

This professor didn't know what he was doing in class. He would skip over examples in lecture since he didn't know how to do them. He also couldn't communicate clearly with the class; everyone I talked to in the class said he was confusing and was hard to reach even during his office hours.

Couldn't understand him, doesn't speak english. You can't see your grade until the semester is done. He told us all of our work was on Pearson, and a lot of kids missed assignments on blackboard and weren't able to make them up.

Can't understand him whatsoever between how quietly he talk & his accent, he constantly gets confused by questions and answers incorrectly and we have to watch him reteach himself how to do it in real time, he assigns >8 hours of assignments/homework every week, and you can't even see your grade until the class is over. for sure avoid if possible.

I took this class online, and the homework is insane. Significantly more than all of my 300-level classes, expect to spend at least 10-15 hours a week if you take this online. If one problem set has "30 questions," good luck because it actually has 150 questions inside of those questions. There are usually at LEAST 8 problem sets/week.

He speaks so quietly, and when you can hear him, what he's saying is utterly unhelpful. Extremely inaccessible outside of class and deadlines are often unclear. Doesn't care about helping students learn. The only way to get through this course is to make friends and stick together through the trials and tribulations of STA 590. Avoid at all costs.
