Unlike a single discipline major, a general major in the sciences lets you tailor your course selection to your skills and interests. You can increase your flexibility by gaining breadth of knowledge in a few key areas at the expense of depth of focus in one area. By using a multidisciplinary approach, any subject area can gain access to the "big picture" or broader context. On the other hand, the classes you select can help you narrow down and offer an interdisciplinary viewpoint on a specific subject.
