Be prepared to do some tough questions on tests and quizzes and always do the homework. I would generally consider him as a solid teacher as he is always willing to give you advice and help you improve. He's a great teacher overall and is nice.
A schedule of the class is posted online, make sure to check it often to see when a quiz or exam is coming up, as there is often no reminder until the day beforehand.
The class was very heavy on quizzes and tests. There were barely any assignments. The assessments are purely off what was taught in class, but there were at least one question on every assessment that required some heavy and creative thinking. His tricky questions made me study a lot more. You definitely need to memorize formulas for each unit.
Practice, practice, pratice. Practice makes perfect. Before a quiz or test, check the textbook chapter reviews or practice tests. They're really helpful, and Mr. Choi uses questions there in his assessments.
Incredibly organized teacher, very friendly, great sense of humor, just don't call him Eric. Tests and quizzes are tough, study hard.
