Subtest deep-dive · WK

Word Knowledge — the highest-leverage AFQT subtest.

WK and Paragraph Comprehension form Verbal Expression, which is doubled in the AFQT formula. A 15-minute daily SRS deck and same-day review of misses is the fastest path.

Word Knowledge tests vocabulary in two formats: simple "X most nearly means" items and short-context items. WK and Paragraph Comprehension form Verbal Expression (VE), which is doubled in the AFQT formula — making WK one of the highest-leverage AFQT subtests. The fastest gains come from a 15-minute-per-day spaced-repetition deck of common word stems plus a same-day review of every missed item.

A two-week plan

What to do, day by day.

  1. Day 1 — baseline.

    Take a run on /practice/wk/; write down every missed item.

  2. Days 2–14 — 15-minute SRS blocks.

    Daily spaced-repetition; weekly mixed review of all stems you've seen.

  3. Day 15 — re-run baseline.

    Expect +5–10 standard-score points if you stuck with the routine.
