First of all I am assuming that you have not even heard back from the SA yet, thus, you do not even have a file opened, nor have you been deemed an applicant, let alone candidate.
I know you are excited, but the next yr will be the rollercoaster of your life. Fill out your PCQ, get your MALO/ALO/BGO assigned to you and then hook up with them. They will be your greatest asset and will assist you through this process. Their experience is very detailed for your area and they can give you more definitive answers to your particular MOCS.
Next, like everybody else said, don't hand it in until the end. It is not a system that they make a decision as they come in, instead they are put in a file and noms will not be given out until AFTER the close date. You don't want to be calling an MOC an updating the file every month with new scores, there is no guarantee that they will update. Also, meeting the mins is typically not good enough to earn that nom from a state like Florida. If you look at any incoming class for the AFA on the ACT min is 25 for Verbal to be deemed competitive, but the class median is 29 (or it might be 28). Notice that is the median and not the avg, thus you want to be above those numbers to give yourself a better chance. I believe the median for the SAT is @1300 out of 1600. The SA's give a high %(60) on the WCS for your PAR (which includes ACT or SAT), having the mins will hurt the score and could be your deal breaker. The reason you will see some appts in late Oct, is because they are typically a Pres nom. and not an MOC. The earliest I can recall for an MOC appt is @ Thanksgiving, for your MOC the appt won't come until at least Xmas, and that is if everybody on the slate has a completed file...if somebody waits until March to hand in their CFA than you will not know until about this time next yr.
Take the SAT and ACT again. Meanwhile download the CFA and spend the time practicing that so you can it it out of the ballpark. Many guys have a problem with the bball (max is 100) and pullups (max is 18). Also start thinking about your essays, write them and re-write them, share them with your MALO/ALO/BGO and let them assist in editing. If you show up for your 1st meeting with the prelim essay and say here are my CFA's, and before I left school for the summer I got the personal emails of my 2 teachers to send recs as soon as they assigned me a file number, you will shine. Don't contact the teachers without getting his input, b/c he might have different opinion on which teacher should write it. I.E. you chose your french teacher, and he says the APUSH teacher will look better.
Remember your MALO/ALO/BGO will be a part of the WCS, even though it is a small % it is still important that he/she ranks you as the best of his candidates.
Good Luck
