Business studies or History?

[?so contagious?]

Im doing IGCSE.im currently taking
business
biology
chemistry
IT
& a language.
maths,english and english lit are compulsory.
im doing pretty well in business studies.i dont have difficulty understanding things.In my test i got 82% and im sure that in the test i'll get back on monday i'll get more than 80%.Ive been taught history since middle school but i only started learing business at the end of last year.History is not something I was particularly good at.Its not really my strong point.There isnt a career that i want to persue in particular but i would like a high paying job,which would mean i'd need to get into a good university.If i were to switch&change to history i might battle to catch up and then get an average mark however if i stick with business i think im capable of getting an A* in my exam.I fear universities might regard history higher than business.im 15 and i plan on doing either IB or A levels.What do you think I should do?Stick or switch?
