Next AF Res board is May. As far as competition, the higher the scores the better. The PCSM is a function of your AFOQT, TBAS, and flying hours. I've noticed that as I took different tests, my PCSM was always close to my AFOQT score. I have seen guys with PCSMs that are significantly lower than their AFOQT pilot score and figured that was a function of their TBAS testing. There is a set of flash-cards that will help you with some of the spatial orientation part of the TBAS. The cuttoff varies with your competition and the needs of the AF from board to board, no magic score that will ensure you are good enough.
