Reviews of professor Leo Duan

Rating: 3.0/5, difficulty: 5.0/5
Professor Duan's class was really difficult. He goes through the material quickly and does not review it. He only assigns two homework problems a week, but they are often very difficult. The exams are tough but he grades easily. He mentions things in lecture that are not in the textbook. I thought the lectures were very boring, but he is caring.

Actually had him for STA4321, one of the most caring and easy professors, borderline too easy. A few HW assignments and tells you exact details of what is on the exam (only 3-4 questions). Lectures are in-depth and easy to follow.

Professor Duan was the nicest professor I had last semester by far. He was very understanding of the difficulties that online learning brought with the course and made sure that all of his tests were fair. He assigned homework about once every two weeks and mostly based the tests on that. If you have to take STA4322, definitely try to get him!

Not the best lecturer but the class is extremely easy to get an A in. He tells you exactly what exam problems will be a week beforehand. Homework is straight from the textbook.
