You're best off speaking to a careers advisor at your school or doing some work experience. Don't worry if you don't know what you want to study, it's not uncommon at this point. Presumably there are reasons you picked those 4 at HL so if for instance you were thinking of medicine (I say this only because the combination of Biology and Chemistry is commonly for that reason), I would do some work experience and then at the very least you can cross it off your list if you don't like it.
