§1 · Before you start
Diagnose first. Always.
Without a baseline you can't tell what's improving. Take a short practice run on each of the four AFQT subtests, log your standard scores, and compute your starting AFQT. That single afternoon saves weeks of generic studying.
§2 · Study by leverage
Not all subtests are weighted equally.
The AFQT formula is 2·VE + AR + MK where VE = WK + PC. Because Verbal Expression is doubled, gains on Word Knowledge and Paragraph Comprehension move your AFQT roughly twice as fast as the same gain on Arithmetic Reasoning or Mathematics Knowledge.
Translation: if you're below the floor and the four subtests are roughly equally weak, study Word Knowledge first.
How to study Word Knowledge →§3 · The weekly routine
15 minutes a day beats two-hour weekend cram.
Vocabulary, math facts, and reading speed all respond to spaced practice. The minimum effective routine:
Daily — 15-minute focus block.
One subtest only. Spaced-repetition for WK; missed-items review for everything else.
Weekly — 45-minute mixed AFQT block.
Realistic conditions: timed, all four subtests in one sitting. Builds stamina.
Bi-weekly — full re-baseline.
Recompute your AFQT. If you didn't move at all, the routine isn't working — see §5.
§4 · How long to budget
By goal, not by guess.
Floor-to-floor (+5 AFQT points).
2–4 weeks at 5 hours/week. Realistic if your baseline is within striking distance of the branch floor.
Floor-to-competitive (+10–15 AFQT points).
4–8 weeks at 5–7 hours/week. This is the most common scenario.
Floor-to-selective (+20+ AFQT points).
12+ weeks at 8–10 hours/week. Add tutoring for AR/MK if you stall above AFQT 60 with weak math.
§5 · When you stall
What to change before you give up.
- Stuck on AFQT 30–40 floor? Almost always vocabulary. Triple the WK time for one week.
- Stuck on AFQT 50–60? Usually AR / MK. Algebra fundamentals (rate, ratio, fractions) carry more weight than you'd expect.
- Stuck on AFQT 70+? Test stamina, not knowledge. Run two full timed AFQT blocks in one sitting once a week.
- Same score for three weeks? You're studying what you already know. Re-baseline and pivot to the new weakest area.
§6 · About line scores
After AFQT, the inside.
AFQT clears the door. Line scores decide which job stays open. If you have a specific MOS / AFSC / rate in mind, check the line-score composite on its detail page; that's the second target you study toward.
