<p>I have the Barron's 9th edition for the Math Level 2 SAT subject test book. However, in class today, I noticed that someone who had an older edition, I believe it was the 5th, that appeared to have a more comprehensive review than the lastest one? </p>
<p>Is there any difference, because I'm planning on asking another person for this book today as the test is in 2 days?! Thank you!</p>
<p>If you already own the 9th edition, it won’t hurt to get the 5th edition if you are saying it has a more comprehensive review. And considering the test is in less than 48 hours, more prac.problems can’t hurt. </p>
<p>I have the 9th edition and it sucks in explaining concepts. It doesn’t have a lot of prac. problems after every chapter either. Although, I’m biased since I’m not the best at math.</p>
