No such thing as working "too hard" in your HSC unless you have a goal, such as 70 UAI, and am getting 90%+ results in your exams/assessments (generally, which in this case is working "too hard"). I'm assuming most of us here are aiming for 90+ and for that to occur, you got to work your @$$ off! I regret not working as hard as I should've/could've and now I'm paying the price - I don' t know whether I'll get 88+ UAI. But that's all my fault, no regrets, I had some awesome times this year and still pwned some exams. Twas fun.
Anyways, motivation is key for success in the HSC.
If any 07's would like some advice about the HSC or any of these subjects I'd be glad to help:
2u/3u math
eco
business
software design
adv eng (can't really give advice on this - I, and my school in general - suck at english)
I'm not some special kid or anything, but I've gotten a lot of 100%'s or close to in exams/assessments for all my subs (except english) when I really tried for them (yeah yeah I've heard people say this
cr@p before about "trying" and all that but meh, make your own judgements I don't mind). So yeah, just PM if you want.
Just remember, stay motivated!
