<p>I'm self-studying Calc AB (taking regular Calc.) Right now i just started integrals (Riemens sum), and I plan to finish all the material in time so that I will have 3 weeks of review.</p>
<p>In those 3 weeks I need to know which study guide to use, Arco or PR. What's the difference between the two, and the advantages of each. Which one goes more in depth, and which one is more concise. </p>
<p>Any suggestion would be helpful. Thanks.</p>
