They're right, the GT score will define what you qualify for in the Army. Also being that you have a degree you qualify for OCS (officer Candidate School), make sure to talk to them about that.
When you go to processing they'll tell you what is available at that cycle time. Jobs open at the beginning of a cycle and then close as they fill the slots. Works a bit different with the Guard and they should know whats open before you go from talking w/ your local units.
