If you want people to take you seriously you really need to fix your spelling and grammar. This is likely to wind up like your last thread.
That said, everyone goes to OCS except Naval Academy guys and they are very much the minority. Your major has virtually no impact on success in flight school in my experience. Most guys were involved in some kind of sport but you don't need to be an olympian. Finally, it is perfectly fine to hope to fly jets and set that as your goal, but you need to keep in mind that most guys do not get jets and the selection is based on the needs of the Marine Corps. It will rub people the wrong way that you only care about flying "fighter jets" and describe yourself as "future ace" in your profile. Your goal should be to a Marine officer first, pilot second, and jet pilot third.
Edit: too late it, it already turned out like the last thread
