If you can learn on your own, going to lecture is waste of time. Her lecture is really really dry. Instead of talking about the stories happened in the business world, she kept bragging about how godd she was as a student bluh bluh bluh. Why? That's because compare with professor Litt, professor Klein and other faculty members from Anderson, professor Zhang does not have any experience from the field.

her lectures were rather slow, but the notes were helpful. she tried hard, but there was some communication difficulty. the tests are easy as long as you do the homework, no tricks involved. very straightforward.
