Allen is the BEST math professor I've had at UCLA. His lectures are super straight forward once you get used to the material, and those combined with the homework is everything you need to do well on his tests. His homework is super helpful but can be a bit tricky doing the problems for the first time. People did super well on his tests this quarter (he also gave us a very extended amount of time) with the average being in the high A range. That being said, I feel like even during a regular quarter his tests would be super reasonable and test you exactly on what he has taught you. Allen is so dedicated and offers a bunch of office hours, and will go so far as to schedule an extra OH on the weekend if he gets a lot of questions. He also responds to your questions super quickly via email or piazza. I would 100% retake this class with him, it has been my favorite math class. Also shout out to Jeremy Brightbill, the best TA with the most life-saving review sessions who will hold office hours until every person has asked every single one of their questions, even if it means logging out of zoom at 11pm.

Honestly, best online notes available I've had yet for a math course. You can take these notes and understand the material in a rather short amount of time because of how well-written they are. Homeworks are difficult, but going into tests after them makes the tests feel easy by comparison. He also has a VERY generous grading scheme for individual tests. Overall, this class was a good experience and very welcomed given my experience with past math professors.

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.

Take a class with Allen Gehret. He looks out for his students and always willing to help. He had like 3-4 office hours throughout the week which was awesome. His lectures were a bit slow in my opinion which I would rather have than too fast. He was very thorough with his explanations and made the material easy to understand. His homework is not too difficult and was the perfect blend of math+programming. He had about 15 homework problems but as long as you did 7 correctly you received full credit. He had quizzes which were extremely easy and median for almost every quiz was a 100%. Plus, he drops a quiz and homework which was a plus. The midterm and finals were easier than the homework and had about a 92% average. He grades on a standard [93,100]: A, [90, 93) A-, [87,90) B+, etc. scale. The TA was alright. His lectures were okay but still good and his worksheets were as hard as the homework if not harder. Long story short, I would definitely take another class with Allen
