Im joining ROTC next semester to become an officer in the air force, what can i do to prepare for the AFOQT?

Once i finish rotc my goal is to become a pilot, not a fighter but a fuel er or a cargo pilot, and i really want to impress by scoring high in the afoqt, my conditioning and fitness is off the charts so im not worried about that, but i heard there are books that would really help, anyone know what they are?
