<p>I think some students choose to double major because they are not sure of the career direction they want to go in, and may not be ready to limit their options, and may have academic strengths in more than field. For instance, a double major in CS (course 6-3) and math (18) is very feasible since some of the course requirement overlap. My son is choosing to do this rather than Math and Computer Science (18c), because he’s interested in going into more depth in each of the subject areas, and is still exploring career options. He’s also minoring in a HAAS subject – I think many students at MIT have broad academic interests and try to take advantage of all that MIT offers while they are there.</p>
