why go to selective?
just because you're going to a good school doesn't mean that you'll pinch out a good uai.....
changing schools into yr 11 is something you'll have to consider for yourself...
if you're smart enough to get into selective school, you might as well stay in your own school and do well in your assessments throughout hsc.
what's the point struggling to come average in a prestigious school, and then grabbing a uai of like.... say, 96
when you could have just stayed in your old school and studied hard by yourself, and come first... then grabbing a uai of 99+??
unless you're exceptionally smart, and feel like you can't stand being around people who are so stupid.... and you consistently get like,,,, 90+ in all of your subjects at school, then by all means, change.
but I'd consider the circumstances in the future if I were you.....
I mean, who knows...if you stayed, you could have been school prefect, src member, sports captain... etc etc.
if you moved... you'll have to make new friends... get settled in.... and bash yourself for only getting a measly average mark, when you used to always come first.
oh the competition is just the thing we all love, isn't it?
