Martin is a great professor that teaches concepts very clearly. He is abstract when he needs to be, but he always cushions hard topics with many examples. His quizzes are more of a preparation tool than anything else (I failed 4 of them), but he rewards for improvement. I got a D+ on the first test (average was 57%) and an A on the Final Exam (average was 67%) and even with the bad quiz grades, he game me an A. I didn't listen to him at the beginning of the course, but once I finally started focusing on the definitions like he said, I did much better.

Martin is a nice professor overall. His classes basically follow the materials of the textbook and there isn't anything that's really out of my expectation. Assignments are from the exercises on the book. Mid-terms and the final are very doable wih a difficulty level below his assignments but a bit above practice exams. He wasn't available for two weeks but had managed to let the TA host helpful review sessions. My suggestion for acing his 115A is just understand every theorem he covered and try to reproduce them on your own. And don't copy the answers when doing the homework. That's it!
