<p>Ok, I have Cliffs but my teacher recommended we also have one throughout the year with us. I want to use two book (Cliffs and ?) since no two books are alike. What do you guys think of PR? 5 steps? Keep in mind this will be mainly used throughout the year. (THANKS!)</p>
<p>My brother, who used 5 steps and which his school recommended, says that 5 steps is good for AP bio.</p>
<p>Everyone in his school gets 5 for AP bio.</p>
<p>It doesn’t really matter what else you use since Cliff’s is the BEST. Just stick with it.</p>
