Question about McGraw Hill SAT I Book!

<p>I'm interested in purchasing the McGraw Hill SAT I Book w/ the CD-Rom. I was wondering if any CC'ers used this text, and it helped them score well on the SAT (new one). Is it a useful investment?</p>


<p>I bought it last year. I think the Vocab section is great because it's loaded with words that you need to know. The grammar section is also very detailed. Tons of math practices, however they are way harder than the actual test. Not very good on CR and Essay improvement.</p>
