Talk to him, Mr. Park's very good at accommodating people's needs (e. g. will shift test dates to the best of his ability, always willing to explain stuff outside of class) especially if you ask him in-person.
truly the definition of chaotic good. I think at least 20% of the grade is based solely on how much he likes you. His tests can be hard, but if you take notes in class and read the textbook before tests it's not hard to do well. Pair up with a friend and take notes every other day. It works, I swear.
