What degree should I get at university?

Just follow your dreams and persevere because at the end of the day you don't want to be looking back and be thinking: what if I took that chance? Get all your family members to support you e.g. tuition, housework e.t.c. Don't forget not to miss out on your childhood too. Universities like Oxford want an all-rounder with creativity as well as intellect. Did you say you are 14 and you have done your french A-Level....if you have I don't see why you can't fulfil your dreams. Good luck and all the best for the future.
