Awful
Professor Park's class is confusing. He's unclear on what to expect in the exams and homework. He gets sensitive when you challenge his point of view. If you're taking this course, just choose another professor.
Awful
Professor Park's lectures were almost impossible to follow. If a topic can be explained in just fifty words, he will use five hundred and leave you more confused than necessary. In addition, he uses his own books as class textbooks. It's counterproductive because, his writing style resembles a Rubik's cube. In short, he talks yet, says nothing.
Good
Professor Park has helped me to think critically about challenging questions. Deep down, he's a very philosophical and ethical person. So, his course has a very technical, philosophical flavor. Also, he leads excellent discussions and asks good questions. His exams are challenging though. However, if you read carefully and think, you'll understand them. Just get ready to read.
Awful
Professor Park is unclear about any of his assignments. He believes his class is the most important too. When he explains what homework should be, he tries to use harsh vocabulary. He doesn't seem to understand as well.
