I was a BIT disappointed with my 94 for ecos and 96 for phys... my school assessment was high for both subjects (96,97) but I screwed up the exam marks (92,95) :/
pre-prepared essays can work, but it is risky because if u do get a question that u can't adapt to very easily then you are likely to write even less than someone who went in and started the whole thing from scrach...
