Don’t know if I can top
@usnausafa2023 for pithiness and accuracy. So I’ll just expound a bit.
NASS is an awesome experience. The greatest benefit for you is that you’ll get a pretty good look at USNA life. It’s not a perfect view — I call it Mid Life Lite — but it’s better than applying sight unseen. But it will have virtually no impact, if even that, on your strength of application. That’s because NASS is a recruiting tool, aimed at attracting high-end candidates, but also those from under-represented groups and regions. So many very “qualified” candidates go uninvited. As far as folks on this forum know (and they’re a pretty informed bunch), there are no points in WCS for NASS attendees. And to put you more at ease, about 3/4 of this year’s plebe class did not attend NASS.
So if you get in, great. If you don’t, not to worry. Best wishes to you.
