<p>You can take 5 classes a semester and graduate from MIT in 3 years in most majors with just a bit of AP credit. It’s 9 credits per class, judging from how few I have I think only 5s count? Or maybe both 5s and 4s but in very specific courses, that sounds more right.</p>
<p>If you don’t have enough you can take the Advanced Standing Exams for courses and “ASE” (pronounced letter by letter, used as a verb) out of the class. The ASEs have very low passage rates, though they do vary slightly from test to test, For this reason, it’s better to take them as a freshman when failing grades can’t show up on your transcript.</p>
<p>I think, but am not sure, that ASE grades do not count for your GPA. The info on that is on this website I believe: [Grades:</a> MIT Office of the Registrar](<a href=“Registration & Academics | MIT Registrar”>Registration & Academics | MIT Registrar)</p>
<p>Anyway, as Juillet and others have said, graduating in three years is definitely not necessary and may in fact be disadvantageous for grad school. There’s more opportunity to get more significant research experience if you stay in UG longer. Take on a UROP (undergraduate research opportunity program, pronounced sort of like Europe, but two syllables), find a good lab, maybe you’ll end up publishing before your UG career is out.</p>
