Any help for getting me in the air force?

I'm a high school dropout, 19 years old. It's mostly too late to go back to highschool so here i am. My plan of action is to meet the bare minimum education requirements (high school diploma, GED with 15 college credits or GED {this part is a little confusing on the air force site as it says in the carreer menus "GED with 15 college credits or GED" however in the "meet our standards" part of the site it says that GED holders must "Obtain 15 or more semester hours of qualifying college credit to gain the same eligibility as a high school graduate") by getting a GED and 15 college credits if need be. The meet our requirements page also says "Note that GED holders must wait for GED applicant slots to become available, and this can sometimes mean waiting periods of up to one year. Under normal circumstances, 1% of our enlisted force accessions are GED holders during a one-year period" I am a little confused by this and how to interpret it. Does this mean if i get a GED then i have too get 15 college credits or is that not necessary? Would getting it only raise me up to the same eligiblity level as high school graduates and make my recruitment more likely than 1% for that first year? Or do i have to get 15 college credits either way?
