*braces himself to get flamed*
If you're aiming for a high UAI, I believe you should definitely take into account the scaling of each subject and taking the highest scaling subjects which you are CAPABLE of achieving a high result in (top 2 bands). There are many people who say stuff like "pick the subjects you like best and you'll naturally do well in them and be rewarded with a high uai" and if this is a perfect world, that should be the case. But this is not a perfect world and the harsh reality is you're competing against people who do high scaling subjects just because, well, they scale high and they do pretty well in them too.
I was pretty lucky because I liked and was good at many high scaling subjects, although I ABSOLUTELY HATED 4u maths I DO NOT REGRET doing it simply because it gave me that extra push needed to get into my desired course. I also did a low scaling subject purely out of interest (didn't count for uai as expected) and I don't regret that either because I learned many things which may be useful in the future (and got me the premier's trophy
).
OK, enough rambling... my point is you have to decide whether the main purpose you're doing the hsc is for a high uai or to pursue your interests. If it's the latter, good on ya, follow your heart
, but if it's the former, then just remember that 2 YEARS ISN'T THAT LONG compared to all the time you have in uni and beyond to pursue your interests. Consider the HSC to be a sacrifice for the long run. Good Luck
Ok, flame away boys and girls!
