<p>Short answer: yes, yes, no. You’ll want to read the page about [AP</a> credits for Class of 2010](<a href=“http://web.mit.edu/firstyear/2010/subjects/ap.html]AP”>http://web.mit.edu/firstyear/2010/subjects/ap.html). As Mollie hinted above, if you receive a 4 or 5 on the AP Calc BC exam, you can either place out of 18.01 and be required only to take one further semester of calc (18.02), or you may choose to take 18.01A “for review purposes” (<– from the AP credit webpage).</p>
