About Word Knowledge

Word Knowledge is a critical AFQT component that tests your vocabulary breadth and depth. Questions come in two formats: identifying synonyms (which word means the same as the given word) and understanding words in context (what does the underlined word mean in this sentence). On the CAT-ASVAB, you have approximately 9 minutes for 15 questions. Because WK is weighted double in the AFQT formula (AFQT = AR + MK + 2 x (WK + PC)), improving your vocabulary has an outsized impact on your overall score. The WK score, combined with PC, forms the Verbal Expression (VE) composite used by many branches.
