You can do my year 12 for me if you want. I'll do the first year of your uni degree and get you that H1 average. Just get me into Bcom/BAeroEng and I'll be happy 
Honestly, I think no matter how many people tell me to relax, there's always that little bit of anxiousness somewhere. I mean, family expectations aside (
), it all comes down to this one year. That's a little daunting for me, but I'm confident nevertheless.
It hardly comes down to Year 12 at all. Even for medicine, your Year 12 results are not the be-all and end-all. There are always other pathways, other options, other opportunities. As long as you try your best you should have no regrets.
I'm a big believer in things happening for a reason. I didn't get any of the scholarships I sat tests for, I didn't pass any entrance exams. I was meant to go through my school's accelerated Maths program (as flawed as it is) and get a 50 in Further Mathematics. I was meant to drop Italian and Physics, despite the fact I was doing well at both. And I'm sure what happens throughout the course of this year will be something that was also just meant to be.
