Why would I be envious, I AM one of the people who did no work and still got in. You're making the HSC sound shit easy, when obviously you worked like a lil bitch (lol @ supposedly doing 100+ exercises and learning/finishing them all in class)
I can still say I put in quite a bit of effort into exams, like cramming sessions before h/y, trials, ext. which easily rack up to 500 hours+. This is pretty much ALL the study I did.
It is the only way to get a decent UAI. You can't 'not try' and get it. EVERYONE has to put in some amount of effort, even if they don't tell you they do.
Mate, if you're getting b6's for MATHS, there's no hiding it. It's enough to show that you nerded it up for the majority of Year 11/12. There is no such thing as 'natural talent' b6 for maths. It requires practice,practice, practice.
You, and anyone else who believes that you studied 40~ hours throughout the HSC should go kill themselves.
And btw.. your friend is lying to ya mate, 'great memory' fuck all. You don't know what they do at home, so you don't know how hard they study.
tommykins = OP wannabe.
