<p>I'm wondering if it would make a difference were I to get prep books for my ap exams, specifically barron's, now or wait for the new editions to come out in february. Also, do newer editions have different practice tests or do they recycle them from past editions. Thanks in advance!</p>
<p>Plus if I already own an older edition should I buy the newer edition?</p>
<p>It depends. If the test has been changed, then the old prep books won’t suffice.</p>
<p>@guineagirl96 If there was no change in test format, then is there any real difference between older and newer editions?</p>
<p>It depends, sometimes they change the practice questions, sometimes they just fix typos and such.</p>
