If it comes close to the application dead line, I would switch to pool 2. I have heard that anyone that applies to pool 1, but is not qualified will be removed from the bid (I have not verified this with HR though). There are 3 ways to apply to pool 1:
POOL 1 - All U.S. Citizens who also meet the following Pool 1 eligibility criteria:
Applicants MUST meet one of the following criteria (1, 2, OR 3) listed below in order to be eligible for consideration in Pool 1.
1. A graduate from an institution participating in the Collegiate Training Initiative (CTI) program and who has received from the institution an appropriate recommendation.
2. A veteran eligible for a Veterans Recruitment Appointment (VRA) pursuant to section 4214 of Title 38 and can provide a Certificate of Release or Discharge from Active Duty within 120 days from the announcement closing.
3. An eligible veteran maintaining aviation experience obtained in the course of your military experience and/or entitled to veterans' preference (must meet eligibility requirements in section 2108 of Title 5, Unites States Code).
Applicants eligible for Pool 1 will not take the Biographical Assessment (BA) unless they voluntarily elect to be considered in Pool 2.
You are probably not a CTI grad. You will not be able to provide a Certificate of Release or Discharge within 120 days of the announcement closing. So your only other option is option 3. Do you maintain aviation experience obtained in the course of your military experience(very broad statement here, so maybe you did fit in)? The other part of Option 3 is: Section 2108 of Title 5, which covers veterans preference. I'll cut and paste a few things from it
