Reviews of professor Don Yu

Rating: 4.0/5, difficulty: 4.0/5
Professor Yu was a great lecturer and he really cared about his students. He gave specific test study questions in class for anyone who came. If you didn't show up, you couldn't get the questions. The only difficult part was that he liked to through tricks into his questions so make sure you know all of your perfect squares and trick identities.

I really liked Professor Yu! He uses the recommended practice questions as a template of what to put on the exams, so try to do all practice questions. He uses the definitions and examples found in the textbook, but you have to attend class to know what he wants you to study specifically.
