I was arrested for marijuana when i was 13 and only have my ged. Will the military accept me?

I have talked with a recruiter from the air force and he told me that they do not grant waivers for a GED (kinda messed up??) BUT he also informed me that if i took 15 hours of college credits that i may be able to apply! (also messed up..) BUT also informed me they may be more lenient because i was so young. Any advice would be greatly appreciated! thank you
