Don't give her false hopes; oh I got an E in methods and it went up to an A....oh yh...but y? cuz u owned yur VCAA exam idiot.
SACS at MHS/Macrob count for less relative to other schools bcoz the cohort lifts yu' up as they smash the exams.
And yh trust me the competitive atmosphere will get 2u unless o' course yur a super uber nerd anyway 
You're in year 10, what makes you think you know the VCE system better than him, let alone call him an idiot?
You are wrong, your own exam mark will not lift up your own sac mark with exception to VERY rare cases. It works on the principle that even if you get 0 marks on your sacs all year, if your whole class gets an A+ on their exam, then you will get A+ A+ A+ on your end of year VCE result. But if you are last in your cohort and you get an A+ on your exam, and the worst exam mark is a D+, you're stuck with that D+ for your SAC mark irregardless.
The competitive atmosphere doesn't "get to you" either, it's just a facade created by students who try to be super competitive.
Let's just say you can afford to make a slip up, and it is easier to get a 36-42 SS than it is at most other schools, but you will still have to work hard to get anything above that, just like anyone else would
