Can't stay on topic through a lecture to save his life. Extremely tough grader. Even if you PROVE to him that you are right, he won't listen. Tests cover small details instead of major concepts. I went to his office to talk to him after I failed his first test, but he told me to get out because I was wasting his time (not including the curse words)

Awful lectures. Ridiculous grading system--when people did poorly he sent an email saying "we weren't working hard enough." I am a junior used to challenging courses, but his lectures are so off-topic and his tests so random it is impossible to succeed. Also as a pre-med this did NOT prepare me for my MCAT, so even more a waste of time. AVOID.

He changes exam questions during the exam, does not accept any criticism. His grading is hard and inconsistent he will say we do not need to know something and then test on that in very specific detail, the list of complaints just goes on. Over half of my class dropped and the rest did not preform well due to his methods.

Dr. Zhang cannot stay on topic during lectures, and will often spend entire class periods talking about Nobel Prize Winners in other topics like Chemistry and Physics. He says you don't need a textbook, but YOU DO because he does a poor job at teaching. EXAMS ARE TOUGH - over the smallest details. Do not come into this class expecting to do well.

Learning anything in this class is a joke. Awful english. Can't stay on topic when teaching. Impossible tests. Extremely rude, sending out degrading emails to students, tells us we're stupid. Did all of the bonus, still didn't help. Thinks he's teaching us important things for the MCAT, but no help. This class makes me want to do bad things. AVOID!

I recommend taking the class with another professor. Seems like a nice guy with a sense of humor, but teaching is not his forte. Has great knowledge of the material, but explains it poorly. Everything I learned was from the book and the Internet. Studying is a guessing game. Random questions appear frequently. Extremely harsh grader. Good luck!!

-Large number of points for each question. You don't know a single answer, you're screwed! -Exam questions VERY vaguely written. Questions do not ask for specific answer. Yet, he wants you to write a 1 sentence answer when the question is not clear. -All over in place in lectures. Irregularly shifts from point to point. Don't know what to write.

I am a senior engineering student and Dr. Zhang's class has given me more of a headache than any of my other classes. I signed up for cell biology with the expectation that I would be learning about how cells work. I've instead learned nothing but specific, irrelevant facts about diseases and listened to countless stories about his famous friends.

Never felt so discouraged and hopeless before. I love to study and love the subject of Cell Biology, but no matter how many hours you study, you will not be even close to prepared for his obscure quiz and test questions. He is hard to understand and his expectations for what is important to learn are unclear. Avoid if at all possible.

This is the worst class I've ever taken. I felt like the entire semester I was unprepared for everything. Instead of trying to understand where the ENTIRE CLASS was going wrong , he chose to believe that we were all incompetent and put in no effort. Most discouraged I've ever felt in my life.

This class was the hardest class I've ever taken. He is the toughest grader that looks for the exact specific answer that he wants or else you get no credit at all. He just cares about getting a Nobel prize and ties it into his confusing lectures. If you wanna depress yourself then go ahead and take it otherwise AVOID AT ALL COSTS!!

His lectures are hard to follow, he gets off topic very easily, and is very unclear of what he wants you to take away. He is a very nitty gritty professor where he tests on minescule details instead of major concepts. The quizes and tests were absolutley ridiculous. He expects you to do ten times more work than other classes. Never felt so defeated

The worst thing about this class that the quizzes are very broad and they only have one question.

Ive never been a complainer about teachers and usually support them when others put them down. Not this time. He is by far the worst teacher I have had in my academic career and everyone I have talked to agrees. His lecutures are pictures, doesnt go over them and then asks test questions about stuff we never talked about on tests. Dont take him.

Pros: He's funny and knowledgeable Cons: Tests and quizzes are tough and the material you are tested on is somewhat unpredictable. Consistently low (by low I mean F to D range) test and quiz score averages do not make him reconsider his teaching style, but rather he'd put blame on students for not trying. Persistently lusts over nobel prizes.

He was an absolutely horrible teacher. unfortunately he was new to our school so i was not warned. All he does is talk about how amazing he is and all the awards he has accomplished, but can't can't seem to teach his students anything related to the class. His tests are ridiculous and you have to teach everything to yourself.... aka read the book!

Not even worthy of 1 star rating. Was cussed out multiple times after going to his office hours for "wasting his time" asking questions. Powerpoints are composed of pictures. Has the lowest grade distribution on record at Mizzou for the class (and that's AFTER more than half the class dropped). Very rude, unhelpful, and AWFUL at teaching. AVOID HIM

I just got an A on the first exam with a new professor by putting in half the effort it took for me to get a D on Dr Zhang's first exam. Exams consist of questions concerning small details that he may have briefly mentioned in between bragging about himself in lecture. PowerPoints only have pictures, so they are no help. TAs agree that he is unfair

Anyone who has rated him more than 1 star in helpfulness obviously hasn't ever been to his office hours. If you actually go to his office hours, he will become frustrated and will often yell at you for wasting his time. He encourages you to ask questions on exams but if you do ask a question, he won't answer it, stating "the question is very clear"

Probably the only reason there are good ratings for him on here is because he bribes students with extra credit to give him a good rating. Dr. Zhang is very bad about staying on topic during lectures. He often ends up spending most of the time talking about former Nobel Prize winners and how he knows them personally. Tests are unreasonable.

I feel really, really bad for anyone taking his Cell Biology class next semester. Along with about just about half the class, I was forced to drop his class with a W. I just finished retaking Cell Biology with a different teacher and received an A with ease. Dr. Zhang has the lowest grade distribution of all Cell Bio teachers and the worst reviews.

This guy is a joke. Mizzou needs to get rid of him, as he truly makes the University look bad. The least sympathetic teacher you will ever experience. When the entire class fails a test, instead of taking responsibility, he will email everyone stating that the entire class isn't trying. Taking this class with Bing is a huge waste of time and money.

An absolute embarrassment to the University.

Every exam I have took was a curveball. His lectures aren't relevant to exams, you can read the book like I did but still be lost on oddly worded exam questions. His take-home exams are 12 page papers that are over techniques in biology and unfairly graded. Very unreasonable and unavailable during office hours (he was out of town every other week).

I took this class a while ago, when he first taught it, so I'm not sure if things have changed. I wanted to go back and reflect on it since it is the worst class I've probably ever taken at Mizzou. His tests are very random. He grades very tough and is unwilling to give back points that you should have earned. Tests over specifics, not concepts.

Horrible. Get ready to do 14 page long take-home exams toughly graded only worth 40% of the total exam score, and sometimes he is so generous as to make a take-home quiz and a take-home exam due on the same day! His logic: it's take-home, so you MUST have time. Also teaches nothing, just talks about his research and WILL TEST YOU OVER IT.

All I have to say is what MyZou says for his student evals: 77% "disagree" and 6% "strongly disagree" that he taught effectively. NOT ONE PERSON (0%) agreed or strongly agreed that they would recommend the class based on the instructor's teach style. It's no secret, Bing shouldn't be teaching

As a 3.7 science GPA student with my lowest grade a B in biochem4270/7240, getting a C+ in this class really does prove how awful Bing is at teaching. He can't properly evaluate student effort and knowledge of the material. His lectures are unorganized, and he could care less about you. Ask him a question, and he is demeaning. Worst professor at MU

Worst professor of my life, do not take his class at all costs. The take home tests takes 2 days. The multiple choice are completely random and doesn't go off of what he lectures. TAKE ANOTHER PROFESSOR

Great class if you love random trivia because there is no structure whatsoever to his teaching material and what he puts on the exams. Every exam is a surprise and the questions are vague. If you ask for clarification on the questions, though, he will state "the question is very clear" and not help you beyond that. Extremely rude professor too.

Horrible professor and class. Tested on irrelevant topics that are not focus of the class. Furthermore, I personally know several students he has essentially harassed and demoralized. Blames others and finds fault in everyone but himself. Stay far away if you want to maintain sanity and confidence.

Dr. Zhang knows alot about biology, but when it comes to teaching he seems to value degrading and berating his students more than helping those that need more assistance. He claims to be here to help the students because they pay for him to do his job, but i guarantee not a single soul would talk to their boss the way Dr. Zhang talks to his student

The worst professor I have ever had. Incredibly degrading, disrespectful, and the worst manners. He told a student they were unteachable in office hours. His teaching is unclear and he expects you to teach yourself 90% of the material. I was excited for this class, but he made me hate it. Mizzou needs to fire him. Would give him a 0 if I could.

Bing is fairly knowledgeable but has very poor teaching and interpersonal skills. But he will not own up to his faults; instead, he will blame his students for not working hard enough. Do not bother going to his office hours either because he will just belittle you. Strongly recommend taking this class with another teacher for a fair chance.

As a senior, this is the worst professor I have had. Expects you to teach yourself material and does not provide study guides, not technologically capable (the class is primarily online), insults students, does not provide answers, expects extensive memorization, and uses intentionally misleading trick questions. Seems to enjoy confusing students.

Sample tests are helpful for exams, but don't rely on them. His grading system is kind of weird. Stay on top of the case studies and active learning because they are on the exams. I don't like this professor, he is kind of rude in more personal settings, and his class is hard even with labs to boost your grade.

I graduated with a double major in biology and nutrition and a 3.77 GPA (and 3.92 GPA in grad school). This is by far the hardest class I have ever taken. It is very different from any other course in that he doesn't really test over concepts, but instead seemingly unimportant details. This is one of 2 classes that I ever had to withdraw from.

Avoid this guy. He is absolutely toxic. I cannot believe that he is still a professor there.
