<li><p>There's no requirement in US History -- just a humanities requirement of 8 classes total over the course of one's MIT career; getting a 5 in US History will get you 9 units of "general elective credit" toward a degree, which will not really do much for you. (The humanities requirement is pretty broad -- I can discuss it further if you're interested.)</p></li>
<li><p>No, MIT does not accept AP Chem credit. If you want to pass out of intro chem, you will need to pass a (notoriously difficult) advanced standing exam at the beginning of your freshman year. However, this is not to say that taking AP Chem in high school is useless -- people who took AP Chem and did well had a significantly easier time in MIT chem than those of us who didn't.</p></li>
