17 and currently at the end of year 12. i think i've ****ed up my a level exams and i'm definitely thinking of retaking the whole year again!

the subjects i'm doing are economics, maths, religious studies and art and i want to study architecture at university. i really want to get into ucl, they ask for ABB and an art a level. i am also considering other good uni's like nottingham etc who also only want art.

If i retake i'll probably take film studies, maths, religious studies and art.

What do universities think of retakes, could this affect my chance of getting into university. If i don't retake, i have no chance of getting into university for a fact.

Any advice?
Any personal experiences of retaking etc??
Any other options i can take?

Is it possible to do a foundation course rather than doing sixth form maybe?
