<p>Both Direct Hits books are fantastic. They contain a lot more than 400 words, too. For example, many words are actually two antonyms or related words (like ‘boon’ and ‘bane’). Other words are lists of synonyms (like ‘trite, platitudinous, banal, hackneyed’). Additionally, littered throughout the book are important vocabulary words that aren’t counted in the 400 but are still helpful, because they are briefly defined within parentheses. Thus, there are probably more like 600-700 useful, SAT-level words between both volumes. I’ve found them to be extremely useful, even impacting my eloquence in everyday speech and writing. If you are having trouble with sentence completions, buy these books. You won’t regret it.</p>
