I'm going to be kinda harsh here, but English and History are going to be more useful generanlly than Drama and IT - they're more versatile into what you want to do, and universities will prefer them.
It depends what you wanna do though - if you want a career in IT, they wouldn't be bad, but it would make more sense to take a computer-related subjects. Drama, I believe you actually need English Lit. for Drama at university (or at least it's preferred or liked). If you haven't got a clue what you want to do, English and History will give you more options than your other A levels.
Also, what would you do if you didn't do these?
EDIT - read down the thread, sciences and humanities are on par with 'likeability' as a general rule, but again it depends which way you go at uni. It is mainly universities who look at A levels, employers look at degrees/equivalent qualifications. So picking your A levels won't directly affect what career you have. If you prefer English over Science, it's best to go with English imo, and vice versa.
