Hiya, I would agree generally with the person above. I would congratulate you on your success thus far, but think it would probably be best for you to choose to drop either sociology or theater studies - however cynical, I would imagine both employers and universities would be happier to see biology on your applications than both of those subjects. You may find that standard offers from universities might well be lower than what you end up receiving from universities you apply to, to account for what might be seen as a 'soft' subject.
(note: I have not myself taken either of your two 'soft' subjects as people call them, I mean no offense to those who take them I am in accordance with the view that even if you take a subject such as these, that by no means they are easy, but they do make you less attractive as an applicant).
