I agree with Amar. Excel in something you are passionate about or at least find a way to stand out. The traditional advice of showing you are well rounded student is of secondary importance. Some students join every club possible and participate in as many sports as possible. That doesn’t make a student stand out. Almost all students join clubs and many play sports. Also with community service, it has to be something substantial. The majority of students will claim on their application they did some community service somewhere during their high school years.
