The first time was the state, the last two times were the NGB and this last one, haven’t been told who did the bumping but it sounds like the schoolhouse themselves did.
already talked to the Division CSM about it. Nothing anyone really can do.
as for overslotting, I have no idea why they won’t.
Keep track of the bumps. You might have to ask for a wavier at retirement if they don't get you in. It's the military waiver's are available for almost everything with a requirement.
