Jake: Did you apply for NASS? That would be the first step. If you did not apply for NASS, then I believe the online app opens April 1.
Applying for nominations from your Senators and Representative is unique to each of them. On their web sites, look for something labeled "Services to
Constituents" or maybe even "Service Academy Appointments." They will each have deadlines, and very specific procedures for you to follow to apply for their nomination.
You should be taking SAT/ACT tests now, hopefully have already taken them at least once. So, you will know where you stand in that area.
Also, there is a book that is very helpful. “The Candidate Guide to the Naval Academy – How to Prepare, Get In and Survive” by Smallwood. There might be a newer edition, but basically the same. Seems like a new author updated it. Very good reference.
:thumb Good Luck!
