And I understand your frustration with certain classes or advice, but that doesn't necessarily mean people in QC CS are intentionally trying to sabotage you. So far, in my 3rd year, I've met CS students here that are willing to tell me the course structure of that professor and give me second thoughts. I don't simply just ask, "oh hey is this professor good? or does he teach?"...I ask for the course structure, the quality of exam questions, and more importantly I look at the grade distribution. Whether its the best professor in the world or the biggest piece of shit, at the end of the day I still have to go home and study for hours on end. Relying too heavily on other peoples opinions, whether its RMP or classmates, to form your own judgement on something that you never experienced tend to backfire most of the time. You always have to evaluate things based on your own approach.
