watatank is right, enuf of this rubbish about scaling, we cannot affect it or change it no matter what we do, and to try and predict the scaling of subjects is impossible, it doesn't matter what school u go to, wat subjects u do, if u put in the effort, u'll get the marks, and the high UAI
its as simple as that
don't mean to sound harsh, but i just get sick of hearing ppl questioning scaling all the time
