Reviews of professor Yubing Sun

Rating: 1.0/5, difficulty: 4.0/5
Bad teacher. Notes, solving processes for example problems, etc., are indiscernible. I have taught myself Statics by watching Jeff Hanson on YouTube.

He's nice but his teaching is so meh. Lectures are so disorganized and just plain boring. You're better off just learning from youtube. Exams don't seem that difficult when you're taking them, and then they take off as many points as possible.

Sun is a good overall professor, he may be hard to understand in lecture but 1 on 1 he explains material well. Homework is very important in this class, exams are similar to hw, hw is hard and takes hours but you must understand it, additionally lots of extra credit is available which really boosted my grade, projects are also meant to get 100s.

The class is pretty tough, the material is complicated and the projects are harshly graded. Professor Sun is a good professor, he has extra help sessions where he will help you and he communicates with the TA's so they can help you as well. Tough grader and the exams are difficult.

Does not explain things well in lecture and then gives the most ridiculous homework. Invest in a chegg account or the homework is impossible. Very difficult class but there is plenty of partial credit on exams and extra credit opportunities so definitely make sure to take advantage of that. The only reason I did well was because of my TAs.

Pretty nice professor was really understanding during online classes. He expects lower grades on exams so don't be too discouraged when you don't get an A. I wouldn't mind having another class with him, but might not be a first choice. Homework could be quite difficult but the test questions were simpler most of the time.

He is an amazing Professor. he hosts homework sessions for 2 hours and sometimes for 2 days week where you will have full access to him. He is very sweet and kind. Cares a lot out his students. If you put in the work you will do very well in his class. If you don't understand something he will keep helping you until you understand.

Great professor, really accommodating during the pandemic. Cares about students and wants you to do well. Tests aren't too hard. The projects are a pain and you can lose a ton of points for small mistakes, so be sure to triple check everything. His lectures are really well done, overall just a solid professor.

Sun is a very smart man, not a great communicator though. Lots of blank faces in lectures and usually he only did examples of a concept, he never actually explained the concept. Online lectures from other professors helped but he was tough on grading. Lots of failures given out.

Lectures were unhelpful and the work is incredibly difficult. He also schedules projects during midterms just to make your life more difficult it seems. Worst class I have taken at UMass which says a lot.
