Although a degree is a nice to have, it won't make you a better pilot in my opinion. I certainly would not waste your money on trying to get one now. What you need is determination and good hand /eye co-ordination. A degree will produce none of these. Determination may produce a degree.
The degree will help in sponsorship and job selection. It is something that is creeping in now I'm afraid. If the Germans had their way, all prospective candidates for a JAA licence would have to have a one!!
Unless you are looking at a test pilot or NASA as a career, then time and money better spent on getting the licences. You will be that much younger and to me, that would make you a better selection prospect if I were interviewing;
I know guys who have left school at 15, i.e. with no qualifications. Two I know have finished up on Heavy A/C and yes, with reputable airlines.
Just because one is not in possession of a degree, it is not a sign of low intelligence. You are born with ability and intelligence. In the genes? Possibly.
