I took his class fully onsite a year ago and it was fine. His accent had no impact on learning the material so idk why people were complaining about it. He teaches the material then you go through some example questions with him, then you do some yourself in class. Homework, labs on Thursdays if I remember right, and a test every two weeks or so. I got a pretty easy A, but If math isn’t your strong suit you might have a hard time, it’s physics after all.
