I  have good grades all As, Bs, and 3 Cs and I want to join football next year can I make it??? I want to be a fighter pilot!!

Honestly, I cannot give you any chances with that information.  USAFA looks at 60% academics (class rank, test scores, gpa, class difficulty, etc.) for admissions.  The rest is made of interiviews, extracurriculars (sports/clubs/jobs), leadership experience, and fitness test score.  You must also be nominated by a member of Congress or other official source.  Look at academyadmissions.com for a lot of your questions, it is a very good site.

There's no sense in not trying your hardest, either.  You'll never know until you apply, and if you don't get in perhaps prep school or a year of college is in your future before the Academy.
