Question about 18X contract

[mhesi]

I want to get an 18X contract and give SFAS my best shot. But I would like to get experience and a college degree first. Right now, I lack the experience and maturity for SF. Anyways, is it possible to join the gaurd or reserves (so I can get a degree and military experience) and when I reenlist as active duty can I get an 18X contract? I was wondering if you could start an 18X at airborne school, because I will have already been through infantry OSUT. I know it would be hard to get a contract after enlisting, because I would have to go through PLDC and all that. Is that possible? Thanks in advance.
