Reviews of professor Tim Zingler

Rating: 2.0/5, difficulty: 4.0/5
He's unwilling to work with students and makes the quizzes extremely difficult. He purposely tries to trick students into selecting the wrong answer on the quizzes. Your grade gets docked if you miss 3 or more classes. Don't bother trying to turn anything in late, even just a few hours after it's due, it's an automatic 0.

Really good, he posts the lectures so you don't really need to go to class.
