I heard on the news yesterday that the SA's had record breaking applications this yr. USNA had over 50% increase in apps from LY, the AFA had an increase of @30%. As I stated earlier ROTC is typically the back-up plan for SA applicants. Due to these 2 facts you need to have the most competitive application you can have. Your ALO will also interview you and be a part of the rec., I would suggest contacting them now so you can use the summer to get a leg up.
Another thing they look at is your hs curriculum. Are you taking the hardest courses available? Have you taken every Honors, AP/IB, Jump-Start class, or are you just taking a couple of them? How many kids go to Ivies, 4 yr colleges, 2 yr colleges, etc.?
For the scholarship you will also need to clear Dodmerb and do a PFA (a little different than CFA). IMHO the PFA is easier, our DS did well on this because for 6 months he trained for the CFA. Download both the PFA and CFA and practice them. The points attributed to your score may seem nominal, however there will be that 1 person who is the last on the list for the full 4 yr ride (type 1,2,or 7), you don't want to be the person behind them! I know this yr there were kids with great STATS, but got the $2K scholarship or none at all.
I know people believe I am the glass is half-full type of person, however, I don't see myself that way. I believe in telling the brutal reality, hoping that it awakens the student to realize this is not a cake walk or a done deal when you hand in the packet.
I think your weakness is your wt. gpa, but if it shows that you carried a 3.0 as a fresh, 3.3. as a soph and 3.8 as a jr, it will be reviewed in a positive light. Your wt. score may be realigned depending on how your school assesses honors, AP. (honors 4.5 or 5.0...AP 5.0 or 6.0?) Also is an A 90 or 94? Does your gpa go purely by an A=4.0, or does it do it like our DS's 95 X4 =3.8? These are all factors in weighting your gpa. For our DS they took his uw, which was @3.68 (I think). For some people their uw and w do not vary as much as it did for our DS b/c of the value assigned to honors/APs. You could have a 3.6-3.7 w, and have a uw of 3.4 due to these factors.
AFA SS should also help you since you were deemed by the AFA as competitive to attend.
Good luck!
