Everyone is freaking cramming, that doesn't mean we'll all get 60 ATAR's. Have some faith in yourself and go do productive study rather than jumping to conclusions before you've even started your first HSC exam.
BTW, go to UWS.
It's a terrible indictment against the education system that a test you do at 17/18 years old decides your career. For the most part, that's what it is and we have to learn to live with it, not work against it.
This.
It's the most effective.
Don't take everyday as a drag, procrastinating on here then trying to learn your notes and feeling like crap. Just get into past papers and use the time you have.
