> As I said, what differentiation there is is due to the initiative of instructors. This is clearly true. I just don't see why it merits devaluing an assessment of the courses. Quality of instruction clearly matters, and that's why I put professors immediately after. But if certain courses play to one's intrinsic motivations, this can be considerably more important to one's learning. A great instructor teaching a subject you care little for can only do so much. But the opportunity to work on things that genuinely excite you can override having a poor instructor.
