being a curator

When I’m older I would like to be a museum curator, I’ve known this for a while but now I’ve got to choose my options (I live in the uk) and I don’t know what to choose, I will choose history and art I know that, I will probably choose Spanish but that leaves me with one more option - I’ve thought about doing French, my school does other subjects like business studies, geography, RE, geography, everything schools normal do.I’m not too bothered what my last option is as long as it’s not further science or further maths.What should I choose?
