His lecture and homework aren't related to the exam. He expects students to read his mind during the exam and write answers he wants to read. If you fail to read his mind, expect B or worse. For lectures, he would explain to you something really simple and just throw you a bunch of papers to read that take more than 10 hr/week just to digest and expect you to understand completely for the exam. Nevermind that he didn't cover any of that during the lecture. He would give you the grade for the exam, but no explanation whatsoever. You don't even get the graded exam back to understand why you got such a grade. I had to ask him and TA multiple times to get my exam back.
Very disappointed in UCLA that this school keeps this professor.
