I'm an Army Reservist with a question about switching to active duty.?

[Ralph]

I enlisted in the Army Reserves last year and leave for basic training in 2 weeks, my MOS is 12M(firefighter). Initially I was coming in for active duty but a week after I took the ASVAB the military stopped taking recruits with GEDs unless you had college credit to go along with it. My recruiter suggested I enlist in the reserves and I could eventually go active duty. My question is what determines how soon I could get on active duty, I don't mind having to start in the reserves but active duty is what I've always wanted, I want the full military experience.
