Do good, not bad. I think the USNA one is actually pass fail, not sure about the NROTC one. If they have a score chart, try to get above a good-low.
Try and max at least one event. The run for the application is only one mile, not 1.5 (just something to have in mind). If you do wind up in NROTC, PT is hella important so if you’re struggling and are set on getting into any kind of Academy or ROTC, just start trying to improve now.
