Do you want to earn a degree and then start classes on another degree?
exactly that
Yes, you can use any left over GI Bill benefits to pay for classes on another degree.
how do you send me the money so I can pay tuition?
We issue payments after each months classes
I'm on the post 9-11 Bill, I thought it was before classes so I can buy books and pay for the classes?
For the For the Post-9/11 GI Bill we pay tuition and fees directly to the school.  Money for books is sent to you at the beginning of the term
can I take classes at 2 schools at the same time if I still have benefits leftover?
Yes, you can take classes at more than one school under the GI Bill if the classes at both schools count toward your degree. Also, the school granting your degree has to consider the classes at the second school to be required in order to get your degree
how much will I be getting so I can budget?
Your payment amounts will be based on the number of classes you go to and the hours spent in those classes
can a dependent also use my benefits to go to community college or another school?
