Worst professor I've ever have. He gave us little time to finish midterm.

Honestly the worst professor I have ever had. Very heavy accent, hard to understand. Frequently gives wrong information and is corrected by students. He cannot explain any of the material well enough for students to understand. Surprised he is allowed to teach college students. 1st exam our average was 24 points lower than the other profs class.

Are heavy accents your thing? Looking for a professor that is very unhelpful in lecture? Do you enjoy teaching yourself the material by scrutinizing online presentations? Are you aroused by unprofessional test administration and teaching practices? If so, Xian Wu is your guy. Need to be self reliant and teach yourself. 1st exam average in the 50's

this professor is really really sucks.

He sometimes makes me uncomfortable. He said the reason he didn't derive equation was we even stuck on algebra but the equation needs calculus based. Physics is not calculus, what he said makes me not feel very well. We mad at first midterm since our ave grade is 50+ and he kept modifying question during exam. but 2nd is better. He is doing better

DO NOT TAKE HIM. He is the worst professor that I have ever had. If you have him you will learn more from google and yahoo answers than his god awful teaching.

Never ever take him. He is the worst.

Professor Wu is easily the worst teacher I have ever had. I went to every lecture and did not learn anything. He is confusing, difficult to understand, and overall terrible. Having no textbook doesn't help either. Exam grades are so low he had to scale one around 40 points. Do not take Xian Wu if you want to learn something

He's honestly the worst, and I say that neither lightly nor ironically. He's a terrible professor and he's kind of rude, especially if you question him. I was unfortunate enough to have him for both 1501 and 1502. 11/10 would not recommend.

I have had the unfortunate pleasure of having Xian Wu for two semesters in a row. He does not know how to teach, his accent can be hard to understand, and his exams are blindside you. On the final he put one problem that was in sections he explicitly said would not be on it. I would not recommend him to anyone. Take any other physics prof

Worst professor on campus. Hasn't lectured one day this semester and when students complained about not being able to learn through his teaching style, he put together a presentation about why his style is the best. Hasn't solved one problem in class. Handwritten notes with illegible handwriting. Mandatory attendance for no gain. Avoid if you can.

Terrible professor. Unclear, mandatory lectures, illegible notes, and very little structure or guidance towards what is on the exam. Feel like I've learned nothing at all about physics and we are now a full month into the semester. Please, take any other professor except Wu if you care at all about learning or your GPA.

Why is this man allowed to be a professor here? He literally told us if we need help, go to the Q-Center instead of telling us his office hours. He doesn't really explain his handwritten notes as he does them. Hard to understand and not worth the stress. If you have to take this class, avoid this man at all costs. Your GPA will thank you.

I took this class because it was listed as a Q course. The professor was hard to get ahold of and the material was quite difficult and I don't think it should have been listed as a Q course.

I had to take this class as a requirement gen ed and it has been a trip. He is reluctant to explain further on questions when students are struggling to understand. He has no listed class hours on syllabus and he canceled our final week of classes so we never went over the final practice exam. If you can switch out, I would.

Worst decision to take this "Doctors" class. Literally have to go through hell and back to understand the notes and lectures. The first day of class he states that this class is very light in math but he must be some sort of math genius because the amount of math in the course is insane. Worst teacher I have had at UConn so far. Please stay away!

just bad nothing more to say

Well, the class was very hard, and the professor confused me. He is fine, but needs to improve his teaching and speaking skills. We have quiz every week and clicker question. The worst thing is sometime you need to answer the clicker question before you learn it.

Awful professor. I could not really understand him and he does not explain things clearly at all.

I found that the hardest thing about this class was how useless attending lectures was for me. I always attended and took notes but I still felt lost. Wu is kind and is willing to help but I struggled a lot with his explanations. He goes fast.

The lecture time is used for reviewing the material and not so much teaching it; so be prepared to learn most of the material on your own time. There are numerous midterm exams and some of the questions are very unclear, not to add the tough grading and lack of feedback given. The final is easy, but I would not recommend this class at all.

You need to fully understand calc, geometry, and trig before you take this class. He says he teaches the math but that's not true. The TAs are rude. He's a nice guy, but the class is so hard. You have to do so much inferencing and higher-level thinking that never gets discussed in class. Way too hard, unnecessary for pnb/bio majors.

Dr. Wu is a nice guy but that's where it ends, he sucks at teaching. His lectures are the most useless thing on the planet, I usually always left there more confused. If you don't already have a good grasp of physics you will hate this class. The final exam is easy though so I guess there's that.

He was such a hard teacher. I couldn't understand the material that was being taught, and he made it so complicated for no reason.

An asshole that gives lectures to hear himself speak. He is an awful teacher and makes concepts more difficult than they need to be. He does not understand what students are asking him and gives them incorrect information. You learn little to nothing and attendance is mandatory. However, exams are decently reasonable and there isn't too much work.

This is a difficult class made worse by a bad professor. He seems like a nice guy, but man, one 10 minute YouTube video is enough to cover an entire 90 minutes of class time. (and in a more organized way too)

Lectures in this class were a nightmare to get through. He would go way too fast for anyone to reasonably take notes on what he was talking about. When this was brought up in class by several people his response was "don't take notes on the stuff in class". He published incomplete lecture slides later and told people to read those. Real helpful.

Here's the thing, I walked into this class with very low hopes and its a good thing I did. Anton and Xavier (TA's) were only thing that kept me afloat. This class was unreasonably hard and its safe to say I will probably have to retake it. Lectures were pointless, went for iclicker. Exams make or break your grade (VERY HARD) :) good luck!

Professor did not care about students learning. TAs graded everything harshly and it felt like they wanted to be superior then everyone even though they did not know the correct answers themselves. Homework was complicated and lecture content did not help you with the homework. There was no review sheet/practice test for exams.

Save both your gpa and mental and do not take physics with him.

He is very hard to follow and he does not seem to actually care about the class. He does not stay for the whole class and when he is there he does not help at all. The homeworks are nearly impossible and the tutorials and iclickers make you come to class even when it is impossible to learn. You will only do well if you study the topics before class

Xian Wu is possibly the worst professor I have had at UConn. He explained everything very poorly, and all the students in my class just went to the TAs for help because no one had any idea as to what was going on. This is a difficult class, so I would suggest taking it with any other professor if you can.

Assignments are structured in a complicated way (tutorials, labs, hw, etc), professor doesn't help at all, and encourages reading the syllabus for every question instead of doing his job.

Avoid taking class with this professor, he doesn't know what he is doing, get ready to study the materials by your self, TA is the best way to reach out for help.

lessons are incoherent and labs are rarely similar to classwork. handwriting is illegible and is difficult to understand. Consistently leaves class before it is over and leaves everything to the TAs. Does not help students with problems, instead tells them to look at posted slideshows, which are always incomplete. AVOID IF POSSIBLE

dont take

Professor Wu doesnt explain the concepts too clearly. He leaves after class during the lecture and lets the TAs (who are great and explain concepts better than the prof.) handle helping during the tutorial problems. Participation is necessary for iClicker and tutorial problems. Make sure to explain as much as you can on the labs to avoid losing pts

never take this class with Wu. He is very hard to understand and if you ask him for help he will pretty much make you feel stupid if you don't understand anything. He doesn't post his slides till after class and there have been times when he hasn't posted the slides at all. The Ta's are a lot better so make sure to see them for help.

Wu is not a good teacher, he does not explain concepts well and it not receptive to struggling students, which is most of the class. He is impossible to reach outside of class and never responds to his email. Probably will be better off with anyone besides him.

He's teaching style is hard to follow, he expects you know all the concepts which he explains poorly in class, avoid this professor at all cost

Worst teacher ever. Please avoid this teacher,

He is a nice person but did not teach that well.

His lecture is a nightmare and did not explain well. Avoid him as you can

Avoid as you can

Difficult to understand

take other prof instead

He struggles to explain simple concepts in a way that is understandable to students. Some problems are because of the already shaky physics department here but he certainly makes a bad curriculum worse. If you must take him you'll get through it, but be prepared to be frustrated at his rude comments and incomprehensible lectures.

choose anyone else. he won't teach during lecture and doesn't show up any other class. TA's do all the work and actually teach as much as possible. loves to repeat himself without actually saying anything to answer questions. don't bother asking questions
