I got A*s in English Literature and French.
My partner, however, got a C in GCSE History and failed A-Level Archaeology, yet he is top of his year at uni doing Ancient History and Archaeology.
Unfortunately, the lack of original thought encouraged in the school curriculum means that your success in a subject there doesn't necessarily mean you will do as well in a degree... I think I would have done better in science at a higher level, as I find I prefer a more solid factual grounding than the complete open-endedness of literary analysis.
