thanks a lot for all the help, people. been revising the maths as much as possible, i can't believe how much i've forgotten! long division seems to have got harder too. to be honest, i'm not that confident about my chances, the maths will probably let me down. right now, my knowledge is barely at foundation level gcse. i used to be so good!
from what i hear, you onoly get one chance at this program, and as it's the only one that odesn't require a secured loan, i'll be completely gutted if i don't get on.
thanks again to all who replied
