Rating: 5.0/5, difficulty: 3.0/5
I took three of his classes in the same semester: CSIS72A, CSIS1, and CSIS83! It was manageable for me, but there were times when it became overwhelming, particularly because 72A and 83 assignments are on a website called Testout and it had lots of Labs. But he is super helpful and understandable! He does reply to emails fast so that's a bonus.
