Ahh, how true this is.</p>
<p>Don’t forget that a double major is not generally more useful than a single major, and that doubling won’t open up grad school or professional doors that wouldn’t have been open already. You can also take classes in any department at MIT no matter what your major is, so if you’re really interested in x, you can take classes in it even if you’re course y.</p>
<p>Double majoring is basically useless except if you’re taking so many classes in the other department that declaring the second major is a formality.</p>
<p>I doubled (in 7 and 9). I am glad I did it. It has not been useful for me in any sort of monetary or graduate-school-admissions sense.</p>
