Accept UCL or SOAS - whichever one you want to go to more.
If you get 3 As at A level and SERIOUSLY want to re-apply, on Results Day decline your offers and set about reading up to apply for Cambridge. This time GO to your interview - I've heard it helps.
If you don't get 3 As, don't apply to Cambridge again. I doubt you'll get an interview.
Calm down on the punctuation though, it's annoying.
EDIT: I thought the UCAS deadline for accepting offers was last week though...so what have you done about UCL and SOAS?
