I understand all the hate she gets but it's out of proportion. Go to class every day, ask question, do homework (optional, not graded). Her strong personality is to emphasize why you need to effort and prepare for tests. I got a B because I realaxed way too much in one of the midterms. If not I believe an A achievable. Very good professor.

Ok the class is hard BUT she's clear at Teaching tho. She is organized, gives you a solid understanding on how to solve problems. She gives you all parts of the puzzle not like other professors who don't give you enough info nor a solid lecture. She is the best. The class is hard because that is just the way it is not because she complicates it.

Here's the thing, learning with her was uncomfortable, she really does make you work for the grade. I have to say that professor Sun is really good at building character! But if you're not good with having your character built then avoid her. She is not an easy A. Her teaching style is different from many professors but overall I really did learn.

Ju Sun is the Gordon Ramsey of Thermo: cares about the subject and that you learn it, but tough to pass. Lectures are long but go in-depth about the concept. HW is the same thing but I just wish it put more to your grade. Her exams take up most of it, and they're brutal. Take her if you can handle the work, but please DON'T TAKE HER ONLINE.

I've taken Dr. Sun for Thermo, Statics and Dynamics, and she teaches these classes very similarly. She gives very clear and detailed lectures, but gives a lot of homework. However, if you can manage your time with the given homework, you've got most of your studying down. If you take her for two classes in one semester get ready to do a lot of work

Considering everything transitioned to remote learning, Dr. Ju Sun has adapted well. I can't speak for how she teaches in person, but her virtual lectures are great. Very easy to follow; her class in general is pretty straightforward. There is probably an easier professor to take, but I encourage you Dr. Sun is worth taking.

Don't take this lady if you don't have to. Especially if you're loading up on courses. The homeworks are abominably long and worth little to no credit. She practically fails you if you don't have your hands on camera (didn't happen to me). This is a weed out class. If you can take it with another teacher then do so.

Professor Sun doesn't receive the best reviews, however, she is honestly amazing at teaching and you can easily tell she's very well-rounded in her field. Although there aren't that many good reviews out there for her, she teaches some difficult classes and the truth is some students want to blame the instructor instead of themselves.

An honest review about professor Ju Sun. The class is extremely difficult in general. If this class was in person it would have been better. She reads from a PowerPoint and never actually does problems herself. . But if you are dedicated you can pass just need to put in hours of homework. I was not, and received the grade deserved.
