Reviews of professor Song Fang

Rating: 2.0/5, difficulty: 3.0/5
Lectures were disorganized and not helpful. Pretty hard to understand, especially with mask and no mic. Quizzes and exams weren't too hard but it was never very clear what would be on them. Project was pretty vague and no guidance was given. Labs were interesting and helpful. He's pretty responsive to email. Overall, don't feel like I learned much.

I really enjoyed Dr. Fang this semester. The labs we use are simple to understand, challenging when you want them to be, and clearly demonstrate the application of the topics. He uses many real life applications in the curriculum, some better than others. I do feel sometimes the topics are sped by too fast, but there is a wide depth of topics, YMMV

This dude is decent, great personality. Course is kind of hard for me but my grade is fine at the moment. His slides are insane though, there are so many in every lecture.

I took his Intro to OS class and really enjoyed it. He does have an accent but the slides explain basically everything. He's available and helpful during office hours and by email. He's very understanding about deadlines as long as you don't push it. Try to email him or the TA ahead of time if possible. IMO he's one of the best OU CS professors.

Worst course I've ever had. Title is irrelevant to the course content. Lectures are useless, broken English and hard-to-follow logic. Almost 0 effort was put in slides, so they're only useful for knowing topics titles. Exam questions are poorly written and can be interpreted in many ways. No partial credit. Not a helpful instructor. sketchy grading

I had him for Intro to OS and again for Computer Security. I still agree with everything; he's easy to reach with questions or concerns, lenient with due dates esp. if you have outside circumstances, and everything you need to know is on the lecture slides (take notes in class of when the slide has a question + answer; they're great hints.)
