<p>2nd Edition on Amazon is $13 and 1st edition is $0.40. What's the difference between first and second and is it worth the $12 for the newer one?</p>
<p>The new one has 3 new tests.</p>
<p>The 3 new tests are actually real administered SATs, the other 7 seven were in the 1st edition that was published before the first new SAT in March 05. Buy the 2nd edition.</p>
