VVV has his own way of understanding physics, and lecturing them out, so you probably need some time to get used to his style. However, once you manage to keep pace, you'll find that he really has a profound knowledge in physics, and his point of views on various materials are thorough and in logic with each other. Each time I ask him a question, I will always get even more than I ask for from his answer. If you choose VVV, it is definitely a hard path, but if you manage it, you'll get much more than you expect.

VVV is I think the best QM professor at UCLA. His tests are tough but fair and with lots of extra credit opportunities. His grading scale is also very generous, so as long as you do the homeworks and score about average on exams you should be fine. The material is also really interesting and useful in any field. Its all just ways to approximate differential equations that can't be easily solved. If you have the chance to take it with vvv you definitely should
