Generation Gap?
In 1984 I scored a 93 on ASVAB and 72 on NFQT. I had two years of slacking in college and a year working as a logger/farmhand before taking it with no prior study.
My son scored a 96 on the ASVAB and 51 on NFQT. He has a B.S. degree in History, graduating with a 3.80 average. He took it two years (just basically hanging out) after college graduation with no prior study.
Point is, in my opinion, for the NFQT: you either have it or you don't.
