ight, let's get this straight. You do not need maths and physics at A-level to be a pilot. You most certainly do not need to do any kind of degree, let alone Aeronautical Engineering. What you do usually need for sponsorship schemes is maths, english and a science among a minimum of 5 GCSEs at grade C or above. If A-levels are required, and they often are, it's unusual to find the subjects specified.
I'll second that. I have an ATPL CD here and it utilizes nothing more than GCSE A-C grade maths and physics.
