<p>What are you thinking of majoring in? (That is to say, for what field and degree would you be applying for graduate school?)</p>
<p>For master’s programs (mostly engineering), it will be fine to have graduated early, especially because odds are you’ll be doing your master’s at MIT – it’s the most common graduate school destination of MIT alums. For PhD programs (mostly science), it’s not a great thing, because they care most strongly about your research experience and professor recommendations, and it’s tough to get as much experience in three years as most people take four years to get.</p>
<p>So in the sciences, the best path might be to graduate in three years, then continue working as a research technician (perhaps with your UROP lab) for a fourth year, then apply to PhD programs.</p>
<p>Of course, I should warn you that most people who are able to graduate early don’t, because they don’t want to leave. They manage to convince their parents that the fourth year is necessary. So just be prepared for that.</p>
