I took summer school to fulfill my admission requirement and with my own calculations I fit my needed average but I'm still very anxious and worried about it getting revoked idk y is there a certain time period that Mac would tell me if my offer was revoked ? I have gotten frosh week registration emails and have registered and all that so does that mean everything is okay?

Did you get accepted via that provincial university application form thingy? (whatever its called) If it says you are in, then you are in.
