How can I prepare for AP Lang and Calc AB

<p>I am (obviously lol) taking those two tests. </p>

<p>I feel ill-prepared for the AP multiple choice but the essays my teachers (supposedly a strict grader) constantly gives me 9's.</p>

<p>My math, I get 20 wrong. But I get most of the free response.</p>

<p>WHAT DO I DO? HELP</p>
