An amazing teacher. His teaching style made so much sense to me and the way he constructs things in class made the class entertaining. He really loves and understands his subject. Very glad I took this class.

5-min quizzes are worth 60% and final is worth 40%. Quizzes are really nerve-wracking. It's unclear what grade you have in the class until the final is over since there is no numerical grade for quizzes. If you do the weekly hw and attend lectures, you will do well. Not a bad prof, just didn't like the grading scheme

Dr. Long helped me understand linear algebra instead of just regurgitating stuff for tests. Attend class(zoom!), do homework, do practice problems you'll be fine. He has a system of five minute quizzes which makes it hard to cheat so dont count on chegg. He tests you on concepts so understand what you are doing and why. Great professor!

Terrific even though in the era of covid. Posts lecture notes (which are super-clear) and went at a steady pace. Answers all questions and very good in office hours. The 5-minute quiz isn't fun but I understand why he did it.

Professor Long is a really funny guy but I don't think he understood what being accommodating meant with regards to covid. With weekly 5 min quizzes worth 60% of our grade... I'd say kinda difficult especially online. He's fairly clear with his teaching but his grading scale was awful and unreasonable. I'm sure he'd be better in person

Absolutely superlative teacher. He has an incredible command over the material and is extremely funny! He is tough but fair. By far the best Math prof I have ever had.
