I wish you good luck. I think it will depend heavily on just how nice the adviser that helps you is and your situation that cause your marks to drop. I mean i feel for you as i was high 80 all three years and this year I dropped for reason out of my control..but I was lucky enough i am a good at BS on exams on keep my offer
Hope everything goes well tomorrow
If you live in Hamilton, i think its good to go down cause it easy to sympathize face to face rather than over the phone especially if you are a confident speaker
