Good morning,
Congratulations on your 4 year! My son received the MSISR scholarship for University of New Mexico. MSISR is almost completely based on the strength of the interview you gave with the Naval Science Officer so again, congrats on leaving such a great impression! The way this scholarship works is that it is functionally a National 4 year with all the same perks as any other 4 year except it can only be use at the HBCU/HSI that you marked on your application. The NROTC department of that school actually nominates you to receive the scholarship and it is non-transferable. Depending on the school, it can be just as competitive as a standard 4 year. If you're happy with the school choice, it's a great opportunity.
