jai5w4, I completely with what you are saying. Don't play the numbers game, just try to be the best candidate you can be. Don't try to be the guy that just pulls down "good enough" stats to get in, be the guy that the admission board COULDN'T turn down. The reason I mentioned class schedules and school selection is because these are very important in the eyes of the board. Do not go to a community college because you think you will get better grades to show USNA, and don't take "fluff" classes for the same reason. The admissions board IS going to take this in to account. You need to be taking calc and chem your first semester to show the board that you can handle the load. These are the two classes that get about 10% or more of the plebe class sent home every year, so showing that you can handle those classes will be a big bonus. You need to be taking them your first semester because you will have to apply immediately afterward to be looked at for the next summers admission. Look in to NROTC either at your school or a crosstown association. A few guys come to USNA from NROTC, and you may decide that NROTC is the way you want to go anyway. If your commission is your end goal try to gain as much information about all of the commissioning sources and go from there.
There are some extraordinary people at USNA that have done extraordinary things, and let this be a motivator to you. There are many, many different paths people take to get there. I knew a guy who got in to USNA with a GED, a couple people with 1600 SATs, a guy who applied 5 times and was 23 before entering the academy, and kids that turned down scholarship to very prestigious schools to go to USNA. The list goes on and on. There are many incredible stories of how people got there, and you could be one of these. In fact, I believe I may be the only person to have been both a cadet at USAFA and a midshipman at USNA. Do your best and you can be one of those guys with an interesting story to tell the other plebes when you get to the boat school. Good luck!
