<p>No, not if you have taken 9th/10th grade compsci and have done well. Just do a bunch of practice questions so that you can recognize and analyze array traversals etc. very quickly. And of course, study all the material from Barron’s so that you know it from the AP perspective.</p>
<p>For example, many array questions will be based on where the iterations start (i=1, i=0) or whether the conditional sign is a less-than or a less-than-or-equal-to, and the effect of this starting position/condition on the output. You should be able to tell in a split second what is going to happen if you change one of these, or if there one of them will cause an exception. Etc.</p>
<p>Also it depends on what your other 3 exams are a lot too.</p>
