Are you sure that is the way it works, could it be that is how it is required for them to do it, but maybe one school had less on scholarship, thus they were able to submit the group much faster than a school with many on scholarship.
I am just asking.
The battalion can submit the contracting paperwork at any time, they don't have to wait to bundle them. If they wait say a couple months so they can have more cadets it s really unfair to the cadet that met the requirements on time, that cadet loses those 2 months of stipend. That's not the way to run a ship so to speak.
