He is okay at teaching, I guess. He always has a "I'm better than you" attitude which gets extremely old. You'd think a teacher would be there for the students and not just to collect a paycheck.
Very nice, and can be very helpful to students if you ask for it. Class is extremely easy
Birdwell isnt too great at actually teaching, which by the way, is the reason he was hired, or that is what I would think anyway.
