I’m not aware of any reserve option. The full contract is 8 years, first three is school then 5 after you graduate.
Didactic schedule is all consuming, especially the first two semesters, but doable just know studying is you job. Group PT once a week, but you will be doing more on your own.
It’s an amazing program most of our class is direct commission, came in with no military experience. We’re about to graduate phase one and move on to clinicals. Haven’t lost a single student. Many are holding 4.0 GPAs. Good luck on you application. Start studying now for the GRE. Try to get your CCRN.
