Why does Word Knowledge have such a high impact on the AFQT score?
Word Knowledge combines with Paragraph Comprehension to form your Verbal Expression (VE) score. In the official AFQT raw composite formula [2(VE) + AR + MK], the verbal score is multiplied by 2. Consequently, verbal ability accounts for approximately 50% of the raw composite value entering the percentile conversion.
What types of questions appear in the Word Knowledge section?
Questions typically appear in two primary formats: direct synonym/antonym identification (e.g., 'Select the word most nearly opposite in meaning to ABUNDANT') or word meaning in sentence context (e.g., 'The commander issued a precise directive').
What is the best way to study vocabulary for the ASVAB?
Rather than attempting to memorize thousands of random words, study Latin and Greek root words, prefixes, and suffixes. Recognizing a single root word (such as 'bene' meaning good/well) allows you to deduce the meaning of dozens of unfamiliar words like benevolent, beneficial, and beneficiary.
