<p>does anyone else's ap bio teacher use tests made up of questions from campbell's question bank? i find them to be pretty hard, lol...i usually get in the 80s range (while most others are getting <70)...are these tests comparable to the ap test? are they harder? easier?</p>
<p>My teacher uses them in tests all the time. Some of them are pretty challenging, but they will help you in the long run.</p>
