Reviews of professor Ryan Oyler

Rating: 1.0/5, difficulty: 4.0/5
Unfair and unavailable to students. Office hours are often cancelled or at times that don't correspond to homework deadlines. Does not teach - you will be better of learning the subject on youtube. Provides only 1 example for most problems, doesn't explain nuanced or harder problems like ones on exams. Can be very blunt and rude in his responses.

Rating: 2.0/5, difficulty: 4.0/5
Recorded lectures were unclear and had easy problems compared to the ones in the test. It was easier for me to understand from the book and youtube videos. I would recommend him if you are good at teaching yourself. Tests are proctored, but he allows you to submit your hand-written work for partial credit.
