<p>I was planning on getting Direct Hits Vocabulary, Rocket Review Core Words, and Barron's Hot Words for vocab and got a few questions.</p>
<p>What is the difference between volume 1 and 2 of direct hits? Where do i buy it?
Where can i get the book for Rocket Review Core Words?
Where can i find Barron's Hot Words?</p>
<p>I also found a flashcard site that contains some vocab from a few prep books. I just found it about 5 minutes ago. I'm probably not going to use it since i'm getting the books but it might be useful for others on this site. I saw a set flashcards with the 250 words from PR Hit Parade.</p>
