I've been in the Navy for almost 5 years. I'm an SK3(AW) and I'm applying for the STA-21, pilot option. I put my package in last year, and I wasn't selected because of my low scores on my ASTB and my ACT. I know I have to study harder for my ACT but how can I study for the ASTB? My second question is: I really want to become a Pilot, so that was my first choice and CORE second choice, but is it true that if I don't get picked up for Pilot I might get picked up for CORE? Or not ? I really want to be selected and I'm trying to build a stronger package this year. I wrote a new personal letter but I would like someone that has been through this process to read it. I'm just getting all frustrated because I really don't know what they want. I would appreciate any help anyone can offer.
