Not complaining bc of bad grades (I got A). He never takes regrade requests respectfully. When you want to discuss a problem with him, he just replies with "no" and refuses to explain why he took off points. Material taught in an ill fashioned way, he defends it by claiming the course was set up a long time ago. Being old does not mean it's good.

Stopple made me hate math for this quarter. His body blocks the chalkboard half the time so you have no time to write anything down. Your grade is entirely 5 exams. No notecard of any kind. You are in essence expected to memorize 75 proofs by the final. The median on the midterm was 17% and by the final it was about 40%. Do not take 117 with him.

Prof Stopple gave a fat curve. He has his own textbook with all the theorems, propositions, and exercises. This quarter, he covered 13 theorems, 27 propositions, and 80 exercises. In order to ace the class, you should try to do the exercises not assigned for hw on your own. You can go to TA and professor's OH for help. Would take his class again.

He is truly a genius. I greatly admire his extensive knowledge and outstanding problem-solving abilities. His teaching is filled with passion, and he always uses vivid examples and clear explanations to help us understand abstract mathematical concepts. Grading is based on a curve, improvement and your overall understanding of the concept.

Stopped is good when it comes to lecturing, but grades unforgivably and will take off points even if your proof is correct. Do NOT fall behind on your work, and you'll be good since his midterms/final are just homework/textbook questions.

Don't take his math 117. It's awful. Doesn't give deatils in his notes. Exams extremely hard. Median score of midtern 1 was 6.5 out of 16. Ruined my GPA. The worst decision I have made is to take his 117.
