Get a degree in whatever you have an interest and aptitude. To dramatically improve your chances, get your GPA as high a you can. It is not required, but practically all your competition for the few seats available will be pilots who have a 4-yr degree. Read the handwriting on the wall. You can fly with about any educational background you can imagine. You do not need to know how to build or maintain any airplane you want to fly. All the aerodynamics you need will be taught as part of conventional ground school. Earn a degree in something that can support you. The degrees that the pilots had in my squadrons were across the board, from aeronautical engineering to foreign languages to journalism to mechanical engineering. None of us wound up on the dole.
Beware of the flight school hype. This is an elaborate process to separate you and your parents from a lot of money. There are almost no seats available now and those that are open are being filled mostly by former military pilots. The least qualified of which have more hours and infinitely better training than you could ever obtain in those pseudo-aviation colleges. Probably you do not have a ton of cash to squander, so invest your time and effort in training for an occupation that will put food on the table. Then go for the flying portion of your life. Not during or before you have the degree.
