Your success (or lack thereof) in flight school will have nothing, repeat NOTHING to do with what you study in college. I was an english lit major and entered AOCS before I had my degree. I was in the NAVCAD program, and as a group we did better in flight school then the "average" SNA. (Not that that had anything to do with the fact that if we failed out, we were chipping paint for 2 years!)
Whether you do well or not has more to do with who your are then where you went to school or what you studied.
Can you think on your feet?
Can you compartmentalize?
Do you get airsick?
Do you handle pressure well?
Are you a dick?
Can you learn a relatively diverse load in information in a relatively short span of time?
Can you manage your time wisely? Can you manage your time wisely when your jet is on fire?
Do you drink beer?
Here is the main thing you need to remember when you pick your school/major - if you don't do well, you won't get into flight school. THAT is the bottom line, and will be a recurring theme throughout your career as a Navy Pilot.
Good luck!
