<p>Liist - Kaplan’s comprehensive SAT list has a 500 word vocabulary list. It performed poorly with just 2 hits in March, 4 hits in May and 4 hits in June. This was far below performances turned in by Direct Hits, the PR Hit Parade, the Rocket Review Core Words and other sources. I am not familiar with the “flip book.” Could you provide me with more details. Thx.</p>
