If you're feeling unmotivated about your classwork, then a major switch might be in order. What classes are you currently taking that you do feel enthusiastic about? What piques/holds your interest most? Don't feel bad about the switch - a huge percentage of people I started MassArt with who swore they were gonna be Graphic Design majors (and make it big) either changed to different majors or dropped out entirely. I was an Illustration major, and for the most part, we survived intact and in major.
