I took german at school and then took (amongst others) Photography a-level which was well worthwhile as it allowed me to have a bit of fun time at college. I dont think it really matters, as long as your maths is alright, just try and get some good grades in whatever you study. I speak german pretty well after working in Austria last year, that will be useful as I understand that the best recruitment chances (within europe) are in germany at present. Good luck!
