He's still new to teaching the course, so he's trying to find his groove. He's a nice guy, but goes extremely slow in class. Sometimes, he spends too much time concentrating on the stuff that's easy to grasp and not enough time on the more difficult stuff. He also takes a long time to get stuff graded, but he may just be a busy person.

This is a tough subject, and he could be a little bit more clear on things. He's nice, and willing to help but he needs to "dumb things down" a bit more, most of my class is barely hanging on by a thread. It's easy for him b/c he has a PHD. We don't so we need things to be presented slower, he could be more clear!!

I had him his 1st semester teaching at OCCC and so it was a little rough. I spent most of the class trying to figure out what he was saying his accent was very thick.

Studied excessively reading every ch. & did all hw and listened in class when I was there. I stopped coming to class becuz it was useless.

Because I took this class in high school, I felt like I didn't have to go to class at all. And plus, his lectures are mainly off of the powerpoints. But he does go through each example and work it out from beginning to end, so that's a plus. Even though I didn't learn much from him, I must say he was a nice professor; he's always smiling! :)

If you've taken AP Chem before this class is REALLY EASY. I usually take my own notes from his power point slides because he does additional example problems on the board.

I would say zhu is a very good professor because he actually worries if you understand the materials. He can be very nice because he wants you to make high grades, he gives partial credit to whatever he can, sometimes it is not what the problem asks for, but if it makes sense he will understand that you tried. He also points out mistakes on labs

Dr. Zhu requires some getting used to. He sends out his .ppts before class, and test reviews but sometimes not until the same day as lecture. I didn't do the HW, but read every chapter and did his review tests. Be adv he uses online quizzes that take on abt 4hrs to complete. He won't tell you the last few grades, so it's hard to est needed grades.

professor Zhou is an awesome instructor, really knows what she's doing. She put you with a partner in the lap to work with. He's always there to help all students, all the time, even when class time is over, she would stay with U to make U understand and assist you to finish the assignments. Flexible with grading!!. I highly recommend her class.

Dr. Zhu is awesome! Took him for Chem II and Chem II Lab. He does have a bit of an accent but it not bad, people just use that as an excuse for not doing well in class. The fact is, chemistry is a very hard subject so be prepared to work! He is the only chemistry professor that grades on a slight curve and he will bend over backwards to help you!

I took him for Chem I lab and Chem II lecture. He is a very good prof and helps you out a lot if you show him that you really care. I went to his office hours a lot and I feel like he graded my exams easier. He is the only Chem prof at OCCC that gives free bonus points on most or all of his exams. Not an easy A though , def lots of studying.

Dr Zhu is a sweetheart and he really cares about his students. He wants everyone to do well. He will help outside of class, even if it's not his regular office hours. He's hilarious. He gives a lot of bonus points on exams if he thinks people need it. His lectures are good, but sometimes hard to follow. I loved his class! His accent isn't a problem

Took this class in the summer, you have an exam each week. He makes sure you understand the material, gives extra credit. Has an accent but it helped me by paying more attention. His jokes made lecture more enjoyable, he really likes students who go to his office and ask questions. Study, do test reviews and your sure to pass.

Dr. Zhu is awesome! His review notes were super helpful, I definitely learned a lot from his clear writings; I even kept them in my lock for future references. His tests were similar to the online quiz with just a few extra thibs from his notes, nothing too crazy or out of the blue like others. Took both chem 1 and 2 with easy A.

I struggled a lot in chemistry and it didn't help that his way of teaching is not for me. Basically just tells you to copy what he writes on the board, no hand outs. If you took AP Chem in high school, you'll be fine. Otherwise, you should definitely study. I have to retake this class...

Zhu was very good at teaching chemistry. He's straight forward and gets the job done. However, he expects a lot from his students. His tests are not the easiest, but if you do the homework and study maybe a day or two before the tests, you'll do fine. A lot of people struggle in his class because of his accent, but it is not too terrible.

I took this course in the summer and professor Zhu is super sweet and funny during his lectures. He explains things well but has an accent that might be hard for some to understand clearly. This class goes at a fast pace since it is compressed. There are tests every week and two in the last week. If you are not a hard worker DO NOT take this class.

I really liked Dr. Zhu! He is so funny and made lectures very enjoyable. He drops verbal hints for what's going to be on the exam. You must do independent learning and study his lecture slides if you want to get an A. He's the most personable chemistry professor at OCCC, I think. You can't go wrong with Dr. Zhu. Don't listen to the hate. He's good!

I have taken Dr. Zhu for both Chem 1 and Chem 2. In both cases, I should have received a C, but Zhu was generous with his points and bumped me to a B. I highly suggest taking Zhu. He tells you what to study for exams. As long as you show up and do practice problems, you will pass.

He is so sweet and cares about his students passing. I took him for chem 2 my second time and his tests seemed much easier than who I had taken before. Definitely attend class. If you have a hard time in Chemistry maybe try another professor because you might find it hard to understand him based on his accent.

never again, I dropped instead of getting an F. he jumps around subjects so you never know where you are. he sucks at replying to emails, he's pretty sweet and pops a joke or 2 but its hard to understand his teaching method. the only grade you get in his class is a test+ quiz grade. nothing else. its like an online class you teach yourself

Zhu is a genuine person who wants everyone to pass but the class was one of the hardest classes Ive taken. Zhu will make sure we all understand the concept but the PPs by themselves during lecture dont feel like much help although he bases his exams from the PPs mostly. I think hes really nice & generous If you need help but his exams are HARD

Took him for lab, his accent is very thick but after awhile you will get use to it. If you need clarification on what he said you can ask him or other people around him. He is very clear and helpful for lab. And if you need help on lab he is happy to help. Just pay attention to prelab/briefing.

His grading criteria are clear. Make sure to do the homework quizzes because they can help boost your grade up. Although his lecture videos can be hard to understand, you can have zoom meetings with him for help. He answers your questions straight to the point. Just expect a lot of studying. Also, rounded my 89.5% to an A

I would strongly advise against taking Gen Chem II online. This course is significantly harder than Chem I, and online lectures are not thorough enough. Prof. Zhu is helpful over email, responds in a timely manner, and gives detailed explanations to questions. However, it was a massive struggle to pull an A in this course due to the online format.

Horrible teaching style, if the subject doesn't click instantly then he will belittle you in front of the class, "YOU KNOW WHAT IM SAYING?" It personally seems like he doesn't care whether you pass or fail. I had to watch videos to truly learn because his shaming approach was not working for me. I don't recommend taking this Professor.

Prof. Zhu is not for everyone, he is very short and tries to speed you along to get through the course without making sure the concept is being grasped then he will make you feel stupid by saying it in front of the whole class. I do not know that this was intentional but he doesn't care about his students well being.

He's VERY condescending!!! "YOU'RE GOING TOO SLOW" or "You're not going to pass this course if you keep it up like this" were actual phrases used & its important for him to know that that is NOT inspirational. Since it was a requirement for lecture, I followed the guidelines and went to 10 labs and got the required amount of points to pass the lab.

I took Zhu this Spring and ended with a D. I took him again this Summer since I thought I would learn better after just hearing the material and ended with a C. He cares about his students but not enough to put in effort to help them. Office hours do not help because he will just explain things the same way as before. He is also very condescending.

Retook his class and ended with a C.

Did not help and just told me to study harder. Most stressful class I have taken. Started with 13 participants, ended with 7.

I had to talk to the dean about my experience with Zhu. This teacher is so rude, condescending, and he will literally yell at you if you ask about your exam grade. He does not grade fair at all. Compare your exams with other students after grading ... trust me. Not a uniform grader AT ALL.

He can be very rude. Speeds through lectures & expects us to understand instantly. "WHAT IS IT?" "ANSWER SOMEONE ANSWER!". Not fun to be yelled at when you're trying to learn. Do not take this professor unless you want to teach yourself everything because he does not explain the material in an easy way to comprehend.

Professor Zhu belittles you in front of class, speeds though lecture or goes very slow to the point where the next unit will be rushed. Take literally anyone. Tests are worth a majority of your grade and some of the stuff on the test he doesn't even go over so you have to teach yourself most of the material outside of class.
