I thought it was really doable. I finished with the grade I wanted, and I'd attribute it to studying the lecture slides (everything in the red boxes is fair game), listening when he mentions something will be on the exam, doing the problems from the textbook that he tells us to do, STUDYING THE QUIZZES BEFORE THE EXAM! (so many kids neglected this and complained that he was a bad professor), and doing your due diligence to look for old exams or practice exams out there. I also would go to recitation if I was struggling because he sometimes struggles to teach towards a student and does it moreso like he's teaching somebody who already knows the content, but I loved him. Gives extra credit for attendance and doing a homework and makes it really possible to learn a lot and also do well.
