Reviews of professor Donald Riley

Rating: 1.0/5, difficulty: 5.0/5
Where do I start? Unnecessarily difficult bi-weekly quizzes. The most boring lectures you will ever listen to. Poor communication regarding grading criteria, yet at the same time the most stringent grading rules. If you want a good grade, do not take him. If you want to learn the subject, do not take him. I have no clue how he got this job.

This is the worst class I have ever taken. All of my professors at UMN have been outstanding, even during difficult classes. This course/professor is the one exception. The average grade in the class halfway through the semester was a C-. Avoid at all costs.

Avoid him at all costs. Lectures are incredibly boring. Although the main concepts are common sense, the quizzes are ridiculously specific and very difficult. Take notes on the readings (basically long blog posts) and learn the specific and examples used in the readings and slides. Seriously the worst class I have ever taken... Avoid him.

He's absolutely the worst professor I have ever had at the University of Minnesota, and that includes many math professors. His lectures are incredibly dull, his assigned readings are from a random assemblage of poorly written blog posts, and his arrogance pervades the classroom. I spent every second of that class wishing I could be somewhere else.

Lecture are awful with no engagement, condescending tones, and just downright boring. Sad to see such a potentially fascinating topic ruined for so many students.
