Even a college student, I remember RMP being absolutely dogshit. You really gotta sift through all the reviews and hope for nuggets of gold. It suffers from the same problem as any opt-in review system. Angry people leave more reviews than satisfied or otherwise neutral/moved on immediately people. I just tried to find people who got As and read their cons section. Not to say the Ds and Fs aren't legitimate grievances sometimes. On the contrary, the pros the low-grade students report are more meaningful. I guess I'm looking for like "why would an A student talk shit?" And "why would a failing student leave kind reviews?" I did try to remember to leave reviews for teachers I liked, but if the next person used my system, which is certainly not unique or special, my review, as a nerd-ass A-getter, would be promptly ignored.
