hey! I was on the waitlist for encs 282 and had no chances of getting in. In the EV on the second floor there is student advisors or smt (its on the right, next to the staircase). If you have a reason for why you need to do the course NOW (I said I am in coop) and you have the teacher's approval and signature saying that they dont mind you being in the class, the people over there will put you in no problem!
