Hit it right on the head here. Hop on the AFOQT scoring website and see what kind of PCSM you will have with increased flying experience (it goes up in tiers, ie. above 10 hours, above 50 hours, etc.). Also, if you dont think you can get any more hours in prior to submitting your package to the board, you could always try and take the AFOQT again (i know this sucks) to bring up your Quantitative score.
From my experience, the PCSM is what counts the most and this is greatly affected by how many flying hours you have.
