Oh really? :/
I pretty sure maths isn't going to count as my grade's quite weak. Although, my grade is quite strong in religion - i was top five but they had to estimate one of my assessment marks so I dropped down. Modern, geography and extension hist. are quite strong as well, my teachers...
It just depends how strong you are in modern and legal and how well you know the content. If you don't know the content well enough now, then I think cramming is a bad idea and you'll just be under more pressure then
what atar you get is dependent on much more than just 'intelligence' imo - commitment and motivation and overall attitude towards your studies for instance plays a huge role
so don't go boasting
you'll look like a twat
I start at 9am and go till around 4, with around an hour's break in that time. Then I try to do at least 2 hours in the evening.
I do two subjects per day - going over notes, writing essay plans/outlines and then essays under timed conditions.
My school's in the 140s
and my ranks;
SOR I - 12/95
Advanced English - 13/52
General Maths - 17/71
Ancient History - 2/33
Geography - 4/10
History Extension - 3/7
Modern History - 2/36
