23 words · Free PDF · No account needed

The PSAT 8/9 tests vocabulary in context: a Reading and Writing question gives you a passage and asks which word fits, and the wrong answers are usually words that are close in meaning. Studying a whole theme at once is what builds that discrimination — you learn not just what each word means, but how it differs from its neighbors.

Read the definition, then the example, then the memory cue. Come back a few days later and cover the definitions — recalling a word cold is what fixes it, and rereading it is not.
