<p>Here's a specific example:</p>
<p>My A&O 3 class requires the 11th edition of a textbook. Will I be okay with the 10th edition? I don't think editions are vastly different...will getting an older edition make any difference on my "learning" (my grade???).</p>
<p>no, i’ve taken that class and i had an older edition. all you really need it for is to fill-in a couple of homework problems and take home quizzes, but you can get answers from classmates. most of the material you will need comes from lecture.</p>
<p>however, you should still get an electronic copy just in case.</p>
<p>Great, thanks!</p>
