Unless you're going to a vocational school the point of an education should be to make you more well rounded as an individual. Although you may be shocked as you go through your career how important liberal arts can be — one thing that amazes me is how much writing one does as an example.

If you look at the very best entrepreneurs they're curious about everything -- be it Steve Jobs and his interest in calligraphy or Bill Gate's current interest in international medical issues. I realize that at first glance these things seem to have nothing to do with tech, but they do as tech intersects with many other fields from finance to law to social interactions (yes sociology!).

In terms of what to study you should pick a subject you have a passion for and go for that — if most teachers see that you find something to be too simple the good ones will allow you to explore most subjects in depth. And in that sense getting the right teacher is just as important as picking the right course.
