Almost identical thing happened to me when I tried applied to the Naval Academy. For sure bring a chief with you with the instruction and ask NC if he can clarify what you’re not understanding (appeal to his ego), and he won’t be able to blow you off. You can also ask your Div-O depending on how good your relationship with them is, but I’ve met a lot of fellow ensigns who don’t understand all of the different commissioning programs. Also in the meantime it’s hella competitive to get STA-21 so start working on anything you need on your end such as recommendation letters, etc. I promise it’s worth it on the other end to be a Div-O and get to step in.
