I loved this professor and this class! He's tough but funny and cares about his students. Class has a lot of material, but it's interesting and the labs are fun! Exams are hard, but if you review all the lecture material you should do fine. He grades harshly at first, but you'll understand what he's looking for by the middle of the semester.Rate My Professors ↗
The worst professor on campus. Has a huge ego and refuses to accept help when he clearly needs it.Rate My Professors ↗

Arnoldo is hilarious and incredibly caring and understanding of the students. He does have very high expectations for grading, but is incredibly accessible outside of class for homework/lab help (or just to talk about life). My biggest complaint is he can be a bit disorganized on the account of him teaching several classes.Rate My Professors ↗
Arnoldo is an amazing person and professor. I am finishing up my 3rd class with him and it's clear he really cares about his students. He is always available for questions and will often work through things with you. His exams are hard but if you engage you'll succeed. Curves the class so that you pass if you tried at all.Rate My Professors ↗
Exams are 2-3 hours and grading criteria is strict. Lacks student-teacher transparency.Rate My Professors ↗
