Hey Colton,
I will second what Dunce said and say the key to achieving 90s across the board is practice tests. Magoosh GRE prep for verbal improvement, khan academy algebra 1 and geometry, and learning all the unit conversions can score you a few freebies. I had to take the AFOQT twice to improve my scores. First time around I practiced only exams in the practice AFOQT books. I ended up with:
P-86 CSO-70 ABM-83 ACAD-63 V-48 Q-73.
After a year of rocking those scores and not being competive enough for a fighter unit, I went back and retook the test. This was after I got my private pilot license which definitely helped with my pilot score. I boosted the scores up to:
P-99 CSO-96 ABM-99 ACAD-91 V-75 Q-95
One Huge difference between my scores is I went from taking the test on paper to taking it on a computer. I was able to answer the questions 10x faster and even go through certain portions of the test twice like the instrument, block counting, and table reading.
Best of luck and keep us posted on how everything goes!
Regards,
Chainsaw.
