<p>Hey, so I'm planning on self-studying AP Bio using Cliffs and maybe Princeton Review. I have the second edition of Cliffs, and noticed that there was a third edition. Does it really make a difference?</p>
<p>makes zero difference. The only reason they release all those new editions is to make people pay more money.</p>
<p>If there are no significant changes to the AP exam for [insert AP course here], then books within 10 years will do. Of course, for textbooks, it’s a different matter as well. Books in the sciences + government may require the newest edition. For math and history textbooks you can buy editions around 3-4 years older than the newest one. Math and history doesn’t change a lot in a few years, but that doesn’t stop these companies from mass-producing them every few years just to get more money.</p>
<p>Yup 
</p>
<p>I do regret not getting a more recent text for comp. gov though. Iran has yet to have an election in the book I currently have </p>
<p>(that may be an exaggeration, as I’m not on the Iran chapter yet It’s just categorized under non-democracy status, which by definition it’s a developing democracy).</p>
<p>Hm…I guess one difference I noticed was how the Cliffs book still used Kingdom Monera to refer to Domains Archaea and Bacteria.</p>
<p>I highly recommend getting the Barrons review book and the Cliffnotes book on practice exams (featuring only 6 full length practice exams). Those are the best out there, especially if you’re self studying one of the hardest and most legit APs out there.</p>

I think that might be one of the biggest differences between different editions of Cliffs but Kingdom Organization is a very small part of the AP Bio exam, so you should be fine.</p>
