<p>There are also a lot of fields at the crossroads between two or more departments. Evolution, which I’m interested in, requires broad knowledge in course 7, very deep knowledge in the software side of course 6, and pointy knowledge in course 18. Because of this I’m majoring in 6-7 and either minoring or majoring in 18. I also want to be a writer, so I’m minoring (almost majoring, actually, but they won’t let me) in 21W. A lot of people (possibly most people, especially people in academia and maybe half of people in industry) criticize me for playing in four departments, because the number of required classes I have to take limits the number of electives I can take, leaving me with less deep knowledge in course 7 and less broad knowledge in course 18 and 6. I also have to take a lot of classes, which limits the GPA I can get. But I feel like the education I wound up with was exactly what I wanted. I guess we’ll see if I made a mistake.</p>
