Are you still in high school? Why are you a poolee if you're trying to win a 4-year NROTC-MO scholarship? Assuming you're 17 or 18, I'm guessing if you've already enlisted, you're in the DEP, and you're waiting to graduate and present your high school diploma in order to ship out? You do not have to, nor should you, enlist in order to earn an NROTC scholarship. What happened here? The only exception to this I can think of is if you've enlisted into the Marine Corps Reserves to finish Initial Entry Training before you start your first semester, which I'm not sure is even doable for a scholarship recipient.
Your stats are stellar, if only to improve your PFT score. About a 245 is the average for OCC candidates, while a 275+ is ideal and competitive. The same should be for Marine Option midshipmen. Best of luck. Make sure you do not have a misunderstanding about enlistment and NROTC. If you receive the scholarship, you must attend college and enroll in the respective NROTC unit to complete the four years until you commission. You cannot delay the scholarship to be used after an active duty tour. If you're looking for ways to commission as an active duty, enlisted Marine, you must look into the Corps' other commissioning programs: MECEP, OCC, or the Reserve Commissioning Program. Try to meet with your recruiter to clear this up. Good luck!
