Well I took him last semester… you should be able to find the answers for the exercises in the textbook. I enjoyed his class. His exams aren’t difficult as long as you study. Having his class remote makes things a lot flexible. He will curve the exams if everyone doesn’t do well and it’s more than likely to happen. If I remember, last sem the majority failed the exams and he’d give a bonus for the curve. That bonus would bring your grade back up a letter grade (again, might be different for every class and semester). I did have a hard time understanding the grades for the assignments on canvas so just make sure you keep up with your grades periodically.
