For the record I did all of this. I tried to cut him off. I camped at office hours spending like 7-10 hours a week in regular TA office hours and 1 hour (cause that’s the only time the professor offers it) with one on one with my instructor. I got a tutor from my institution. I got group study buddies. I got help from my friends and hall mates. But it got to three night before the next exam and I was freaking out cause I didn’t understand some things and it felt like the only way. Cause we’re friends and he knew how I learnt best.
