Sant wasn't too bad, but the online delivery format (for covid) was awful. His course was asynchronous, so during actual lecture he just played his recording via screen share on zoom. His mic was absolutely horrendous and sometimes his speech was just incomprehensible. Additionally, he sometimes messed up his recording so you couldn't see him working through the problem. His teaching style was to do a brief concept overview, then solve 5ish example problems. The example problems were quite similar to the hw, which is about 6 questions per week (very doable). His exams were fair, although the 2 hour time constraint was REALLY pushing it for me. Sant as a professor seems quite unapproachable, but the TA Byron was really helpful.

IMO, he was not a good professor who cared about the students. He was very snappy and had the TA lecture the course on multiple occasions. He apparently had to travel to Asia about three weeks before the class was over. He simply had his TA lecture the course, whom had no idea what she was doing. I would avoid him if at all possible for 101. He has good credentials, but I would not suggest him for 101.
