Alright thanks, realistically the only ranks I could improve are Bio to about 3 and chem to 2 after trials. Also I'm assuming maths won't be counted towards my ATAR, because it's by far my worst subject (plus I've done no study for it concerning trials). I'd drop to general if I could.
If I did relatively well in the HSC for the counted subjects, would it be possible to push up to a 73? Or am I just being overly optimistic?
