The subject is very interesting and challenging, although this is just the preliminary stuff. The book, Kittel, is horrible and goes over a lot of stuff in an unsatisfying level of thoroughness making you want more.

Jiang is OK as an instructor, not amazing and he basically sticks with the book. The exams, especially the final, are carbon copies of the homework. Nearly every question of the 8 questions on the final were exact repeats of the homework, so if you just spend quality time on the problem sets and study those, you'll get an A in the class.
