At least at the time I took this course, Jerry was a graduate student teaching in lieu of a professor due to the school's insufficiency of 115A professors. But Jerry has been one of the best lecturers in Math I have had, along with our TA Josh. He would sometimes make mistakes on the board that could go on for a while, but those were rare and he was VERY invested in teaching 115A. Going to his office hours is essential because he goes over homework problems in detail. Of course, you should attempt the homework yourself before going, but he does a great job working through and being attentive to all students' questions.
Grading for our quarter had several schemes:
HW was always 20%. Then, either:
- Midterm 1 20%, Midterm 2 20%, Final 40%
- Midterm 2 20%, Final 60%
- Midterm 2 40%, Final 40%
- Midterm 1 20%, Final 60%
- Final 80%
You can just see here that there are a lot of opportunities to pick yourself back up if you mess up one or even both of the midterms. I did worse than I wanted on Midterm 1 but eventually got used to the class structure and did way better than I anticipated going forward. His syllabus is extremely clear and explicit; his instructions on logistics in general are very specific and to the point, which was very helpful and I wish more professors would do that.
It was a somewhat challenging intro to upper-division mathematics (as you'd expect it to be) but it was not stressful and I felt my educational experience and performance were very well cared for.
I have hardly any complaints about his class. I'm going to miss Jerry; I hope he considers lecturing or becoming a professor beyond this point. If he teaches another quarter, take him!

Hard class in general. Grading was super strict/hard, points were taken off for ANYTHING. But lecture content was clear and the professor writes lecture notes in OverLeaf that are clear and useful for review. Midterms had a theorem sheet on them so we did not have to memorize any
