I am in year 12, but at gcse i did triple science french business and history.
If i were you i wouldn't do business, i found it so boring- just common sence. I thought it'd be economics and stuff like that, but it was about the lay out of an office, and why call centres save money...
French was very good, adn i'm doing it for A level, but i'd advice triple science (of you can't do both). In my school if you were in the top sets for science you'd do triple science and have to opt out to double, whereas everyone else would do double. So there were four classes doing triple and everyone else wasn't. So in my school at least the classes which tended to be most focucsed and least diffrutive were the triple science ones. Also triple science sets you in good stead to do science A levels which you might want to do (i didn't really have much idea in year 9, dunno bout you :P)
