<p>Hey so i still have to start studying for AP bio exam, i just ordered the cliffs 2013, i dont know if i should get crash course because i heard that the stuff is mixed up in it such as the review on amazon. Any of those that have, is it good? worth getting?</p>
<p>Crash course is the ultimate tool the day before test to read instead of cliffs which is too wordy for last day overview. </p>
<p>However, if there are factual errors in crash course then it wont be worth getting? </p>
<p>Which books should i get for this new AP exam for bio????? HELP!</p>
