Get A Levels I would say, At the end of the day airlines have to assess you intially as a training risk, be that risk high or low. Now if you have a degree or at least the ability to get into a university it suggests to the airlines you have the capacity to absorb the groundschool and theoretical part of a type rating course. Of course with regard to handling skills and all of that, your CPL/IR MCC course(s) however you choose to do them will cover the flying part hopefully!
I personally never took sciences or maths beyond GCSE, I don't have a degree either and I'm flying for a UK airline so having said all of the above at the end of the day it's whether you are what the airline is looking for that counts!
Good luck!
