What you need is the ASTB study guide!
Click here for the pdf. Good luck.
To get into OCS with a flight contract, one must pass a written/computerized test battery and then take an additional physical in Pensacola, FL. Last week I took my Aviation Selection Test Battery (ASTB) and passed with a perfect score! Some of the recruiters had never seen a perfect score before, so I was thrilled as I had to study in between my final round of college finals ever. The study guide was very helpful, so if you are thinking of going pilot, that is your ticket in based on my personal experience.
Now in June to complete my application I am going to be flown down to Pensacola for a few days of physicals, and I’ll let you know what that entails!
