Yes, go see the MATSG education officer. Talk to your squad leader or barracks NCO or class advisor or whatever they're called now, basically, the first NCO in your chain of command and fill them in on the situation. They should be willing/able to point you in the right direction. Expect some "You need to learn your MOS first" from them, and don't blow it off, but they shouldn't try to stop you from seeing the education officer.
If the education officer is on leave or TAD, talk to the career planner. More than likely the career planner won't be as well versed on commissioning programs as the education officer, but some are. If all that fails, send me a PM.
