I love professor Gehret. His lectures are super organized and clear. I would definitely recommend taking 115A with Gehret if this is your first proof class. His homework can be sometimes challenging but it covers every topic he talked in class. And my TA Jaehoon Lee is so far the best math TA I've had. They both put a lot of efforts into teaching and they care about how well their students are doing in the class. Most people did not like 115A that much, but Professor Gehret made it great. His tests are fair too.

Maybe I'm just happy I got a B, but Professor Gehret is an excellent professor. You could tell that he cares about his students and makes sure that the material be made as clear as possible. He uses his own lecture notes, which act as basically the textbook. These notes are pretty comprehensive and are basically all you need to know, but that does by no means that lectures aren't helpful. He is a pretty good teacher in general, and explains the "why," to get us to see the bigger picture.

Homeworks are fairly difficult (around 8 questions that he writes himself), and we had 2 homeworks per week because it was a summer session class. A lot of people dropped because of this I think. It was also 25% of the grade too, so there was a lot of pressure. He acknowledged the difficulty of this though, and hopefully change this in the future. Although he'll probably give one a week during the school year anyways. But tests are very very fair. Half of the test is recalling definitions. He started doing true and false, and boy are they tricky. I should have just left it blank

In conclusion, you know 131A is a hard class anyways. But Professor Gehret makes your hard work worth it by teaching in a way that helps you understand concepts and learn how to study proofs.
