I did very well in this class. It is very methodical. However, the workload required by Lu in this class is ridiculous. He assigns homeworks that require the use of MATLAB, making each assignment around 30 pages long. Also, Lu seemed to enjoy assigning these sort of homeworks even during week 10 of the quarter.

Lu is easily the worst professor I had at UCLA. Keep in mind I did very well in this course, but I taught myself the material COMPLETELY ON MY OWN. Lu cancelled class for 3 weeks of the quarter, yet expected us to self-teach the material in his absence. During week 10, Lu left the country, cancelled the final lecture of the class right before the final exam, and told us to study the last chapter of the book on our own. Absolutely unacceptable. The TAs were extremely confused what he would test us on for the final exam. He refused to answer emails about certain topics, and did not show up to his office hours because he was out of town most of the time. I would say avoid this professor, but you have no choice if he teaches 106 the year you have to take. Horrible, horrible professor who made a class that much more difficult by making you self-study. Do every problem in the book, or at least the ones that are applicable and you will do fine on the exams (which have averages in the 50s).

If you're scared, you should be.

Similar to the previous review, the workload is pretty heavy. It started out okay but then started heavily involving programming (Matlab or Polymath). The amount of work was sometimes ridiculous; however, a lot of it was altering the same code to generate various plots/graphs. If you changed your perspective on the hw, it was actually a decent way to let the concepts sink in and a good learning tool to practice problems with. I just wish there was less of the Matlab/Polymath since it is not supposed to be a computing course.

Besides the hw, I thought the exams were fair - starts out easy, then a medium problem, and then 1 problem that makes you think a little bit more. If you did the hw and actually understood the concepts behind them, then the exams were not bad at all. In my opinion, Lu was more straight-forward than a lot of other professors. The TAs (or at least 2 out 3) were great and would love to have them again if given the chance. They were concerned with the students learning, responsive to emails, and gave hints out for the exams during discussion sections.

If you want to do well in this course though, make sure to read the book as well as review lecture materials. I wouldn't mind having Lu again for another course. He just needs to cut down on hw.

This is the first chemE class that I feel I've really learned something useful and practical. I really liked the Professor Lu's Lecture. It was very straight forward and easy to understand. He also really cared about student learning in his class and always tried to answer our question in the class or in his office hour. Like other reviews said the hw in this class was pretty time consuming, but it was very helpful to prepare for tests. Even though hw required Matlab code, it wasn't hard to do that because we could use a same code to do other problem. Unfortunately, the last lecture was canceled due to the fire alarm, and all the classes was cancelled at UCLA , so It wasn't Pr. Lu's fault. In general, this class was pretty good and organized. Even though the subject of this course is hard, the instructor made it easy to understand. So, in order to do well in this class, I really suggest to really learn hw and lecture notes.
