Join the actuarial society, you'll make friends there. (btw you might seriously think about changing your secondary to science or single degree because any job u can get with applied finance you can get with actuarial studies, stats/maths science double gives u advantage in more quantitative roles)
You should definitely go for it if you like very quantitative applied mathematics/statistics/probability. As for being shy(im shy but not as shy as u), its ok but you should work on it at university by joining societies etc, otherwise it'll be harder to find an internship/job later.

you'll get zero for ur whole paper... tbh don't worry about it. What's done is done and you can't do anyhting abuot it. No point worrying about a sunk cost. Focus on ur next exam
expectation? excepting?? dont know what u mean. I'd personally do HSC chem. Draw diagrams and equations to support ur answer. btw should've done this at the start of yr 12
i've seen this like 7 times already just play around with an atar calculator... and its obviously possible i got 99.60 in 2012
MX1 99,MX2 96,Chem 95,Physics 93,Eng Adv 88
shitty internal marks dont mean anything. Your ranks and ur internal marks compared to everyone else does. and also if you could get 75+ Raw for all your subjects given that they scale well(eng adv, economics, chem, physics, MX1, MX2) its very close to 99 atar. A 75% raw is not as easy as it...
