What is the difference between these two?

<p>What is the difference between The Insider’s Essential Guide to SAT Critical Reading and Vocabulary and
The Insider’s Complete Guide to SAT Vocabulary: The Essential 500 Words?</p>

<p>I am willing to buy one of these which is better and they differ in what?</p>

<p>I really need to know this by tomorow. Any help?</p>

<p>I don’t know any of these books but let me take a wild guess. hmm… one is “Critical Reading and Vocabulary” and the other one is just “SAT Vocabulary” </p>

<p>hmm…
The book that says Critical Reading and Vocabulary has 600 words for vocabulary while the SAT vocabulary has only 500 .Isn’t that a bit weird?</p>

<p>I don’t have the money to buy both.</p>
