FOUR SUBTESTS IN, ONE PERCENTILE OUT
AFQT = 2 × Verbal + Arithmetic + Math

Eight categories, and where the doors close
CATEGORY IIAFQT 65–92IQ ≈ 106–121 · 28% of the reference group
Qualifies on AFQT for nearly every enlisted job; line scores and clearances decide the rest.
Category boundaries checked against DoD Instruction 1145.01 (Oct 2026). Category V is barred and Category IV capped at 20% of accessions by 10 U.S.C. § 520; DoD sets a tighter internal benchmark of about 4%. Branch minimums for diploma holders currently sit around 31–35 and change with recruiting conditions; check a current recruiter source.
