I plan on applying to Imperial, Bristol, King's College, University of Manchester and University of Leeds. I currently do Biology, Chemistry, Business and Math, but I am planning to drop Math. This is because I am predicted A* for business, A for Chemistry, A* for Biology and A for Math. Now Imperial requires A in Chem, Bio and another subject, if I drop Math, I can apply with an A*A*A whilst if I drop business I can apply with A*AA. Dropping math means I have a higher chance to get into the uni I want, but I will not be doing an important subject like Math. So my question is, does imperial and the unis I mentioned recognize Business as an A-level subject and do they prefer applicants who take math over business? I would like your advice on what to do.
