Didn't get through all the material in time for the final (still put it on the exam tho). Mid, rushed lectures. Homework problems are unreasonably difficult at times, and thus not good test prep. No practice tests were given either. Final exams graded, but still not released WEEKS into summer. Cmon. Some more effort could be shown.

Whoever wrote "meh, course was not interesting and she didn't do anything to make it better" was so right. Boring lectures (at 9:30??). Doesn't ask questions in class. Lectures were solid but very crammed; regularly finishing classes with content left for next class. No practice tests before exams. Don't get me started on difficult of hws. Bad.

Solid lectures that are clear and makes sense, HWs are tough but reasonable, and decently difficult exams without being merciless. Overall a good introduction to electrostatics without feeling terribly hard.

Chill prof, not too difficult but not an easy class just because electrostatics can be a bit challenging. Overall, a class that if you put the time into studying the concepts well, you will do more than fine.

Electrostatics is a hard concept to digest but Luo did a great job of introducing it to us. Lectures were great and somewhat intuitive, and she helped where it got a little fuzzy. Tests were fair and difficult, but curved nicely. Homeworks are hard but help you learn a lot. Office hours were also great.

Meh, physics 23 was already boring and she didn't do anything to make it less boring

Very good physics professor! Made the concepts clear, and was always willing to explain further, incredibly kind and caring. Tests are very easy, and she clearly wants to just give fair tests that most people can do well on. Also she gave us snacks on test day so immediate 5.
