Denied from College flight School for GPA reasons, what should I do?

To start this story there is a little background info. For the last 4 years, I have been serving in the Marine Corps. I work in a job that isn't in aviation. But I have grown an interest in flying since I have been in. Before the Military, I went to college for a year and dropped out cause my passion was the Military. When I dropped out, my GPA was a 1.3, terrible I know. But I thought, well I will have GI Bill to pay for school and if I decide to go back then I will fix it. I am getting close to the time of my discharge and have spent the last 6 months looking and applying to schools that take GI-Bill, Part 141. One of the ones that caught my eye was TSTC in Waco TX. I was excited and applied there. I was working with their VA office. I got letters of recommendation, wrote an essay on why I should be considered, and had everything sent to their office. I was accepted into the school but was not even considered for the flight program due to my GPA. Now, I am franticly looking for solutions. One thing I did consider was the accelerated programs, not ATP. I was looking in particular at Thrust flight, the only thing that concerns me the $100k price of flying. I also heard that these accelerated programs may get you 0-100 fast but are less inclined to getting one into the Airlines because while a degree is not required, it is defiantly preferred. The bonus to going to college is that my GI-bill usually pays for the flying and the courses associated with it. My main concern is whether I should consider going to college and fixing my GPA then applying to schools, making the process take 4-5 years. Or should I consider an accelerated program and just disregard the degree and save my GI-Bill. ​ TL;DR : I was denied to my flight school of choice after Military because of a low GPA. Now, not sure what to do. Fix my GPA and go to college for flight school, or go to an accelerated program and paying the $100k price tag.
