What should I be doing to make sure I have my GI Bill available when I want to go to school after the Army?

Serve three years of service and be honorably discharged. That's all you have to do, and it's all you can do.

I agree with everyone that made a comment. You just have to get an honorable discharge and that it. I will recommend that you use TA while your in so that way you will be closer to your degree. I hope this help and have a good day.

Make sure you are honorably discharged at the completion of your service.
