    PHYS115C . Jin C 1 Year, 3 Months Ago

    Definitely seemed to improve a lot according to what I've heard from previous students. Class was very organized and lectures were clear. Homework took a while but was not unfair in any way. Easily accessible outside of class, helpful office hours and responds to emails very fast.

    Good lectures and also great typed-out lecture notes if you miss lecture. Both midterm and final were similar to practice exams. Homework is difficult but helpful and interesting. The class is fast paced but 115C seems to be like that with any prof.

    PHYS115A . Jin C 3 Years Ago

    His homework is difficult, but doable. They are all from the textbook's exercise or modified versions. The difficulty is not from the professor but quantum mechanics itself. There are unexpected questions in exam. You have to use your concepts creatively to solve it. You have to be good at math otherwise this course is a disaster.

    PHYS115A . Jin C 3 Years Ago

    LOTS OF HOMEWORK and he always finished teaching the topics on the day the assignment is due. Theres no relation between hw, lecture, practice final, and final. Accessable outside the class, but he's missing in last two weeks. You cannot avoid Professor Jin if you want to finishe 115 series, so good luck.

    PHYS115A . Jin C 3 Years Ago

    You wont be able to write your homework until the day he finished his second lecture everyweek, leaving only 4-5 hours to do the homework. There's no relation between lecture, assignment, and finals. Prepare to be exhausted after you take the course.
