<p>^uhh i don’t think you need to memorize any formulas. they give them all to you on the ap test if i remember correctly.</p>
<p>one thing that might be helpful to know, if you don’t know already is that if you can’t answer the first part of a FRQ problem, but can answer the rest if you had the answer from the first part, just make up an anwer for the first part and use it throughout the rest of the problem. you’ll only lose credit for getting the wrong answer in the first part, but readers will give you credit for using the wrong value correctly throughout the rest of the problem.</p>
