I think you may have the incorrect view of education priorities.
The order generally is Mission first, then education for the mission.
There are a few courses, like Combat Divers and HALO, which are unique in that they are longer and have a moderate failure rate. Consequently, they are scheduled independent of the mission.
Other courses like Animal Husbandry are classes a team can take together or if needed a couple of the team can take.
You may go thru your entire career and never need some of the "other" courses.
IF & WHEN you get to a team you will get the "other" education, as required.
Until such time, You should stay focused on the 25M target.
