<p>I currently have this year's Kaplan Biology E/M book, which I am quite dissatisfied with, and just checked online and found out that my school's library has the Barrons review. I know that Barrons is a really good review for SAT Bio, but it's the 13th edition from 2002. How much does the material change from year to year? Would a book from that long ago still be current enough? Or do I need to go buy a second review book... or should I just stick with Kaplan.</p>
<p>the material will not change. the only material that will change will be history.</p>
<p>nope material doesn't change at all! you're good--they just republished to get more business</p>
