Mostly because I want the challenge. School isn't fun for me unless I have to push myself. And also because I'm planning on doing my study abroad in England in about a year and a half during the second half of my junior year so I want to get as much done as I can before I go in case there isn't a very wide range of classes to choose from. I just don't want my study abroad to make me fall behind. So I'm getting my prep work done early.
