<p>There are two, but which book is the most effective?</p>
<p>Try a little searching next time before asking something.</p>
<p>Both books are good. Volume 1 primarily focuses on Level 3 and 4 words. Volume 2 primarily focuses on Level 5 words.</p>
<p>Both were really helpful for me but the second volume had much tougher words</p>
<p>The 1st volume had a higher frequency of words on the SAT compared to the 2nd volume though.</p>
<p>Would I be better off using the two Direct Hits books or memorizing Barron's list of 3000 SAT words?</p>
<p>Certainly. I feel that barron just recycle their GRE words</p>
