Introduction
Vocabulary questions test word knowledge directly across four formats: synonyms (same meaning), antonyms
(opposite meaning), homonyms/homophones (same sound/spelling, different meaning), and one-word
substitution (a single word replacing a phrase).

Strategy for Synonym/Antonym Questions
💡 Exam Tip: If you don't know the exact word, check for a familiar root word or prefix — e.g., "bene-" (good, as in benevolent) vs "mal-" (bad, as in malevolent) — root-word knowledge can help you eliminate options even without knowing the full word.
✅ Practice Focus: Building a running list of synonym/antonym pairs (regular revision) · Distinguishing homophones by meaning-in-context · Common one-word substitution phrases · Using root words/prefixes to guess unfamiliar vocabulary.
