Not the best lecturer, but amazing in office hours, one on one. Interesting character who is very funny, but isnt too odd. Very standard and reasonable grading policies - weekly homework thats about 3-5 problems, a midterm and a final. He is a nice guy whos always willing to help and can explain things clear as day when you ask.

I really enjoyed this class even though I hate lin algebra. The only complaint I had was the grading scheme: hw, quizzes, mt1, mt2, final were worth 20% each. I understand he did this to help us out, but for me, I scored high on the exams and low on the hw and quizzes, so I ended with a B. He's very helpful though and never condescending.

It was his first time teaching a big class so he was not very accustomed to it. He made the lectures hilarious. Iclicker questions not based on accuracy. But I felt like I was memorizing the content rather than actually learning in the class. Struggled on the midterms but the final was made extremely easy.

Bigelow is pretty hard to understand verbally, so pay attention to the slides since they have the most content. The midterm and final were both extremely easy, and he obviously wants students to receive an A. If you do the homework and memorize the concepts, you'll get an A.

Not a very good lecturer. It's boring, dry, and uninspiring. Homework and tests are straightforward. Overall an easy class if you can bear through his monotonous lectures and outdated memes (posts it online which I'll throw him a bone for this) Though a boring person to many, I cannot help but feel some sort of whymsical, caring spirit within him.
