How did you only get 60 percent of the post 9/11? Did you only serve a year and a half active duty?
There is no doubt that going to a community college with low tuition and low fees is the best way to go. Depending on your state, you should have enough to cover flight cost. Be sure to look at the state Veterans benefits. In Texas veterans can use what is called the hazlewood act after they have used their entire GI Bill. That act enables veterans to go to a public college/university with tuition and fees covered for another i believe 36 months.
Good luck - and enjoy those benefits - I just recently got out of the military myself.
