I got 65.10 and was up for 36 hours partying before one of my exams...I fell asleep during it too...Was getting a tattoo in the lead-up to my English exam...
My mate who we didn't see for 3-4 weeks before exams because he was locked away studying got something like 67, and he was a bit of a book worm/nerd, doing specialist maths etc...
I just finished a pre-app, trying to get an apprenticeship as a sparky now....I'm 25 in Jan.
Before I signed up for the pre-app I was worried I'd be in a class of 17 year olds...My class of 10 had me, 2-3 22 year olds, a 25 year old, a 35 year old and 49 year old...then a few 18/19 year olds...
