<p>I have the 2nd edition of Cliffs AP Biology (printed in 2001). Has the AP Bio test changed significantly from 4 years ago or is this book good enough for the current test?</p>
<p>i'm pretty sure they changed the format in the past four years. section I has something like 30 fewer questions than before. but the content hasn't changed much.</p>
<p>The only change I know about was for last year (04-05) - they cut the MC section from 120 question to 100. Other than that, I don't remember hearing about any other changes (which is why old AP Bio tests are excellent for studying)</p>
<p>I used Barron's, and it got me a five. Then again, I took my test extremely late, around May 29th (ISEF).</p>
