<p>one of the areas that I need to improve on is sentence completion. So i’m wondering what is the best book to help me do better on these questions.</p>
<p>I got an 800 on the CR section, and I never used books for vocab or memorized vocab lists. When I took practice tests, I’d write down the words in the sentence completion options that were foreign to me and memorize them afterwards. </p>
<p>I did get one vocab question wrong, though - dilettante (n.) is an amateur or dabbler in some subject.</p>
