When I talk with students individually about their coursework, I don’t tell them not to undertake double majors. But if they do have two majors, I ask them to explain why they have two, and if the reasons don’t strike me as valid, I recommend that they reconsider. Why do I question double majors and heavy course loads? Because college was genuinely fun for me, and I would like you to have the same experience. I was excited to be able to concentrate on three areas — physics, philosophy, and of course, chemistry, even though chemistry was my one single major.
