Without wishing to re-tread over ground covered with regards academic qualifications, they are what they are and that's it. If you meet them, apply. If you don't, then go away and work so that you do next year. This will also demonstrate a good example to BA as to how much you want it, if you are fortunate to get through to the interview stage.
As we all know, this application process numbers in the thousands of applications, so BA are not exactly short of the type of person they are after.
That may sound a little harsh, but we can debate at length whether the requirements are fair (or even relevant!) but they are what they are so a hoop that must be jumped through!
