ive just finished uni and recieved the full student loan, which is your tution fee (repayable), maintenance loan (repayable) and a maintenance grant (FREE/ non repayable). these 3 things you are assessed on given your parents household income, for instance, my mum was a single parent with 1 dependable child on less than full time hours, so i was entitled to the maximum loan + grant, however my mate had both parents living at home with no dependable children and recieved less, as parents are expected to contribute.
Now, with the tuition fees rising, you should have really applied and got in this year, then deffered until next year and your fees would remain at the current price that you got accepted at, rather than the new inflated prices next year... if your able to get into uni this year, do it, but ask to defer until next year so that the fees remain at this years prices!!
none of the loan has to be repaid until you earn 'x' amount P/A, and even then it will be a minimal amount per month, maybe £20ish.
That said, I wouldnt worry about the loan too much, just get it and experience it! Uni was the best time of my life!!!!
hope this helps!
