<p>As I just noted in another thread, Stanford describes what it is looking for in applicants as "intellectual vitality." Whatever you can show that shows you have that will help your cause. I know a current Stanford student who had significant marching band involvement when he was in high school. But he also pursued, evidently, much more challenging courses in high school (partly by dual enrollment in a local college, as I recall) and he had many more high test scores as part of his application. </p>
