<p>Alright so i was wondering if any of you knew where i could get access (whether it be link or a document you can send to me) to any and all former AP Calculus AB or BC tests that have to do with either "Implicit differentiation" or "related rates". I really want to work on these two parts of calculus and would be forever grateful if you can find me problems that have to do with those two. </p>
<p>I believe the MC portion of the exams is released once every few years, and you have to buy them. I don't know of anywhere online where you can find them.</p>
<p>If you want to work on implicit differentiation and related rates, there are tons of review books that have plenty of questions that are made to mimic the exam questions. And of course, you have your book, which probably has some additional practice at the end of the book. Or you could just look online for practice:</p>
<p>Related rates questions simply aren't on the multiple choice part of the examination very frequently because of the very nature of the types of questions themselves. Multiple choice questions are designed to be finishable in 2-3 minutes, and the vast majority of related rates questions simply don't fall into that category for very many students.</p>
<p>As far as implicit differentiation goes, there were a couple in the link that snowia gave you. Implicit differentiation simply doesn't get that weird for the multiple choice, so frankly, any practice in this topic should help you out.</p>
<p>And as far as having them deliberately from old exams... if you don't have the answers, what good does it do?</p>
