For 131AH (Honors) with Menz.

TLDR: Great guy, but subpar teacher. For reference, Prof. Menz uses Prof. Monica Visan's 2019 131AH notes on her website (and lecture notes can be found by searching Duc Vu 131AH).

Statistics:
Midterm Average, Median: 20.39 (68%), 20.75 (69%) out of 30
Final Average, Median: 60.5 (79%), 61.25 (80%) out of 77
Grading: 20% HW, 20% MT, 60% Final

Prof. Menz is a fantastic "personality" for math and would do his best to showcase the inherent beauty of math, while trying to not emphasize the importance of exams too much (despite the heavy weighting on exams...). He's very approachable and friendly in helping students work out problems.

However, his teaching is exceptionally subpar. His board handwriting isn't great and he'd rarely write out full statements and proofs, while sort of willy-nilly explaining the intuition behind each proof at times. Sometimes it felt like you were just watching him try to figure out the proof himself. Expect to self-study A TON.

His exams were tough, but expected for an honors analysis class. Definitely do the homework and practice exam questions, as he will likely take questions from there or ones that are heavily inspired by them. Office hours are also great to attend, as sometimes he'll go over questions he himself finds "interesting" :) and might show up on exams.
