Reviews of professor Qi Li

Rating: 3.0/5, difficulty: 4.0/5
Dr. Li is a really nice guy, he cares about what he is teaching, and he doesn't grade too hard. His lectures can be kind of difficult to follow sometimes though. We only got through 4-6 slides per class and he would talk for the entire time in between with little visual aid. Although, his lectures weren't mandatory.

Borning lectures. She just talks to herself. Exams are not directly related to lectures. You need to learn notes from former professor by yourself for exam. Participation accounts for 20% that you need to provide "quality discussion" that is very subjective. No homework. Exams are all multiple choices. 1 question lose 1% course grade.

The grading criteria on the projects was not clear, but the exams were easy. The homework and quizzes were pretty difficult! He is very thorough when lecturing.

He's a great guy. When you converse with him, you can tell that he's passionate about what he lectures.

You have to do well on both exams and the presentation.

Easiest ECON class at PSU. Sweet teacher. Just attend 10 classes and ask question in each class. No need to pay attention. Easy two mid terms with no finals. One group project with 5 people and a 5-10 min presentation. TAKE THIS CLASS.

His homework wasn't bad but unfortunately the book didn't go into much detail. His lectures were a hit or miss depending on the day. I had relearn stuff from class sometimes. He's very nice and takes late work.

I'm honestly not sure what is going on with this professor. Since the professor established this class, he has basically been a "ghost" to all his students: any questions posted in the class forums go completely unanswered. Multiple times there were broken video lecture links he did not bother to fix, even after emailing him. Would not recommend.

I just hate how the book doesn't teach all the code that the homework requires. I have to find answers other ways.
