I am in y12 and do wjec maths, further maths and physics and am supposed to get AAA or AAB, respectively at the end of the year (predicted from my teachers), im pretty sure that im not gonna get those grades and instead get something like ABC as ive really half arsed revision this year. I want to get AAA in y13 to be able to go to the uni I want, but i am worried that i am going to be uncapable of reaching these grades due to my AS results, how hard would it be to achieve AAA given my likely AS results, and would I have to do resits.
