GI Bill benefits were set up to help pay for college, graduate school and training programs for Veterans and their family members who qualify to cover all or some of the costs for school or training.
Have you ever applied for GI Bill benefits?
I have and was awarded Post-9/11 GI Bill education benefits.
Since you were awarded Post-9/11 GI Bill education benefits you GI Bill Statement of Benefits will show you how much of your benefits you've used and how much you have left to use. I suggest you view  your GI Bill Statement of Benefits.
