Good luck if you have her. I genuinely find myself learning more about the class when I do not attend and I just read the textbook. In class, she moves too fast and instead of explaining difficult concepts, she says to read the textbook. When asking questions in class to clarify some concepts, her answer always makes me more confused than I was.

Would not recommend. She is not understanding in anyway. Not clear and makes everything so much more confusing than necessary. Cannot answer questions clearly. Does not seem to care.

Horrible professor. Does not care about students, moves too fast in class, you don't even really have time to take notes in her class. This is an introduction class and she doesn't teach it like one, she's rude when you ask for help and doesn't even actually teach you anything. If you take her class, be ready to teach yourself everything.

Horrible professor! She is teaching an introduction to chemistry class and acts like we are chemistry geniuses. She is supposed to teach basic chemistry and does not teach at all. She puts questions on the board without teaching you how or even what the question means and expects you to know it. Do not recommend taking any class of hers!

Be prepared to teach yourself, she does not seem like she knows what she is doing ever. She does not help, sends back rude and passive emails. Her tests are opposite of what she says to study. Better off getting an education through khan academy to maybe pass this class.

The averages for her first two exams were 48 and 52. She is a very smart lady, just doesn't know how to teach or speak English well. You're better off skipping her class and only going to SI sessions.

Hundreds of students started this class. We are down to about 40 that actually attend. She simply doesn't care if we pass. Doesn't seem to care if we go talk to her after class or not. Isn't helpful. My outside tutor taught me more in one afternoon than I learned from her the whole semester. Worst professor I've ever had. Maybe 10 will pass.

She does not teach the concepts very well and moves very fast. She also won't stay behind to get questioned answered. Basically, a cliff notes version of the book so not worth it.

She has very tough exams. They are mostly free-response questions, with just a couple multiple choice questions. You have to be very confident with the concepts to pass the exams. There are 4 exams and homework, and the homework is weighted about equal to 1 exam. Reading the textbook and doing countless practice problems is essential.

Terrible professor who shouldnt even be considered a professor. She does not teach; the lectures are word for word from the textbook, and she goes through the topics with no depth. Her class is a waste of time, energy, and money.

Lecture barely get into detail. She goes way too fast not really making time for questions. Was dismissive when I asked for help. Tests, homework, and lectures are wildly inconsistent. You will teach yourself from the book and online with this professor. Worst professor I have taken.

Doesn't care about her students what so ever

Be prepared to fail. This professor doesn't teach and has left class because her students weren't getting it. I have an A+ in my lab for this class and am failing her lecture.

She's rude when you ask her questions and talks down to you. Didn't give us any study material and told us to do the practice problems in the textbook but there are no answers so I don't know if I'm ever doing them right. Don't take her class, it'll ruin your GPA

She does not care about her students whatsoever. She's extremely rude when you try to ask questions. Lectures, homework, and tests are very inconsistent. Does not teach and straight up left lecture one day because we did not understand lecture.

I have never taken a worse course. She does not give extra credit, barely has any grades, does not curve grades, and does not help when you ask for it but instead gets annoyed and gives you a passive aggressive comment. I go to EVERY SI I can go to because they teach me more than what I "learn" from lectures. She does not teach!!!!

She teaches off of the textbook and literally reads off every line. You can tell she is a very smart lady, but her "teaching" does not help you at all. She does not curve or give extra points whatsoever. If you forgot to put the electrons on an element, the whole thing is wrong. She will ruin your 4.0 GPA. She is also a very rude professor.

If you have to take OCHEM at Texas Tech, do NOT take Dr. Xu. She lectures straight from the textbook and goes super fast. She's difficult to understand and you cannot read her notes. OCHEM is already a difficult class and Dr. Xu makes it 10x harder. The only thing I learned was when I went to SI sessions.

I would not consider her a professor. Her lectures come straight from the textbook, and she does not bother to explain the material.

Professor Xu is not a good professor. She is a very tough grader & doesn't give extra credit which is very annoying for a class of this difficulty. Her lectures come straight from the textbook and don't go in depth. Doesnt care about her students, people ask for help she is dismissive. Once she walked out of class because students didnt understand

WARNING!! This class is supposed to be hard, but she has taught me very little all semester. My tutor, who i have once a week, has taught me more in depth, but I still am not passing her course. She does not answer questions w/o an "are you dumb?" sigh or comment. She does not give extra credit. She does not answer emails with a concrete answer.

There is only one hour per week that she goes over things. This is online, mandatory, and incredibly glitchy. You effectively have to teach yourself the material. If you get stuck doing this class, do the Learning set with the reading, then the quiz and mastery. It will take you 5-8 hours every week to do the hw/teach yourself.

Every other O Chem professor at Tech has empathy for their students except Xu. Her lectures are x3 speed, she does not give out reviews like every other professor. Lacking in her email responses and praises only students who attend office hours, which are at a time that conflict with most peoples' schedules. No redeeming qualities, dont take.

Xu is not a good professor for organic chemistry, she is hard to understand and does not understand why you dont comprehend the material. She says in class after test if you thought the test was hard try harder. She does not give extra credit unless its in the test, but the extra credit shes given was stuff we havent learned.

This class felt unnecessarily difficult. She is difficult to understand. Her homework is worth more than the exams, homeworks are due on test days with a lot of chemdraw questions. Exams are 100 pts, including final, extra credit is 6 points on the exam if you answer all parts. No partial credit either. Take Dr. Mayer if you have to take OCHEM.

Professor Xu goes way too fast during lecture. I found it much easier to read the textbook myself and take my own notes instead of going to class and taking notes based off her lectures. I taught myself everything in this course. Your grade is mostly based off of exams, so make sure you get good grades on the tests. No extra credit is avaliable.

Not helpful in any form. Acts rudely when asking for help. Avoid this professor

She was not a good professor! I had to take her class again because I failed with a 69 tanked my GPA significantly. Her lectures are awful, she just reads off a powerpoint from a textbook. Your grade is based off you exams, does not provide extra credit nor does she curve test for you unless it's the final. Goodluck...

This professor give little to no help in the class. She only lectures off the slideshow. This class a weed out class because if you get behind you will not do well. The only grades in the class is the homework and the test, and there is no extra credit given. Also if you fail the final you can fail the class.

She was absolutely awful and not clear with any of the material.

If you are not great at chem and need more help than others. EVEN if you're good at chem. DO NOT TAKE THIS CLASS. I repeat DO NOT TAKE THIS CLASS. she will not work with you or explain anything. she reads the pp and lets you out of class without learning ANYTHING.

She is very difficult to understand and does not teach very well. You have to do a lot of work on your own outside of class to understand. Please to not take this class with her if you can avoid it. Very heavy on tests and Final. Does not offer much help outside of class. PLEASE TAKE IT WITH SOMEONE ELSE.

Don't get me wrong, Xu cares a lot about the success of her students, and is very kind, but for SOME reason it really doesn't click for anyone. Hw and lecture heavy. Practice exams this semester were only 33% related to the exams. Will be taking again for grade replacement. Take Mayer instead. Trust.

DO NOT TAKE. SHE IS TERRIBLE.

DO NOT TAKE!!! I passed this class and I still would recommend another professor. NO extra credit, NO curve, and all open response exams. Take another professor, many give extra credit, curve, and use multiple choice.

This is my second time taking Dr. Xu, she is as worse as I remembered. Having her for 3305 is no joke. I haven't met a single person who has something positive about her teaching style and course structure. I have attended lectures, SI session, office hours, and yet will be having to retake this class. Please avoid taking her if possible!!

She spent a whole lecture getting mad at us for not answering one of her questions about a topic we hadn't gone over yet. DO NOT TAKE HER. I get where the nice ratings are coming from, but all of her lectures are just going over examples that can be found in the textbook. She explains NOTHING and the free-response has no partial credit.

If you don't do good on the exams, you're screwed.

Dr. Xu is not someone I would recommend especially if you are not strong in the chemistry subject, her lectures are pointless to go to because 1. she's hard to understand and 2. she goes so fast and doesn't show how she got the answer. Beware of her grading

really bad, if you don't do well on the exams, you are screwed. she doesn't give ANY extra credit except for once or twice if you get a correct answer in class. also no test makeups, even if you missed one for medical reasons. she also reads off of slides so if you don't learn well that way, don't take her. if you do take her, GOOD LUCK.

This is a very difficult professor to have, if you are not too strong in chem then you should wait for another to be available. Extremely fast speaker, must attend all lecture, and I recommend buying the ochem text book and going to all SI sessions to have a better understanding of what she went over. Good luck and May god have mercy on your soul!

Becoming a navy seal is easier than passing this professor class!!! Prepare to read your textbook on your own time and try recording her lecture she goes extremely fast. Test are written with little room for error, write too little or too much information points get deducted. If your pre med, no you are not after her course. GOOD LUCK!!!

Occasionally on the way to her class, I would cross the street without looking just hoping someone would hit me before i got there... even then I'd still be expected to make up what I missed from being in the hospital, but it seemed worth it.

If I could give this professor zero stars, I'd do it twice. She belittles students, explains nothing, and somehow makes you feel at fault for her lack of teaching. Whether you pass, fail, or spontaneously combust from stress seems completely irrelevant to her. If you value sanity, pick literally any other professor with a pulse.

This course wouldn't be so bad if the professor was better. Even with all of my effort: going to class, doing the homework, going to SI sessions AND the learning center... it was not enough for this woman's class. I'd sooner step into a gladiator arena unarmed or jump through a ring of fire over shark infested waters than take this class again.

Do Not Listen to the ratings that state that the professor gives you everything that is on the test, because that is literally their job. It is the same as stating that I should have passed this class if only I had downloaded a new brain called brain 2.0 for better note memory. Be aware, when taking course to video record lecture and buy textbook.
