If I recall correctly, you had applied to 20 schools, including the Ivies and had been looking for ways to get admitted to all of them, or at least as many as possible, and were hoping the NROTC units could help with admissions decisions. Some of the advice you received was to narrow your focus and decide on your top few schools and focus on those. That is still solid advice. I imagine if you actually get the phone calls you are talking about, one of the questions they may have of you is, where else are you looking at. If you rattle off 19 other schools, the next thing you may hear is a dial tone. (Or dead air since the chances you are on a land line are slim) Like
@kinnem said, if your questions are about the school, they should be directed to the school. If they are about the NROTC unit, those would go to the unit. Keep in mind, most of your time will be spent as a student, not a midshipman. The fit of the school is the most important thing. While different units may have activities, customs and traditions that are unique to them, they all teach the same curriculum and unit staff turn over on a regular basis. How many of the schools you have applied to have you visited in person? If possible, try to visit your top schools. Contact the NROTC units in advance of your visit and see if you can schedule a meeting with them during your visit.
