I guess if you know your studying priorities and set them correctly, then all should go well with lots of focusing, studying, researching and a few cups of tea/coffee (whatever you prefer). And balance is very imporant too, take breaks etc.
Also if you don't understand a concept, go through...
English - 89 | 5
Maths - 92 | 6
Science - 88 | 5
Geography - 81 | 5 (Wasn't expecting much from it anyway)
History - 94 | 6
Computers Skill - 96 | Highly Competent
Not that good compared to some others, but I'm really happy :D
