The ASTB consists of the following 6 sections:

The 3 highlighted sections help comprise the OAR score while all 6 sections help determine your PFAR, AQR, and FOFAR scores.

The average OAR score is around a 50 and 80% of the test takers score between 40 - 60. Any score greater than 60 is quite favorable. Take a look at the following graph for a breakdown of scores from 2004:

• The Academic Qualifications Rating (AQR) is predictive of academic performance in aviation preflight instruction (API) and primary phase ground school.
• The Pilot Flight Aptitude Rating (PFAR) is predictive of primary flight performance for Student Naval Aviators (SNAs).
• The Flight Officer Flight Aptitude Rating (FOFAR) is predictive of primary flight performance for Student Naval Flight Officers (SNFOs).

You may take the ASTB only 3 times in your life. Therefore proper preparation is of the upmost importance. You are allowed to retake after 31 days of your first test and you are allowed to take your third test 91 days after your second test.
