I can understand falling out of school-mode, but it may be good for some people:
http://www.usnews.com/education/blogs/the-college-solution/2010/07/20/8-things-to-know-about-a-gap-year"Occasionally students are admitted to Harvard or other colleges in part because they accomplished something unusual during a year off. While no one should take a year off simply to gain admission to a particular college, time away almost never makes one a less desirable candidate or less well prepared for college."
4. Plenty of schools would love you to experience a gap year. Harvard is so high on the benefits of a gap year that it's been proposing this opportunity in the acceptance letters for decades. Princeton University launched a bridge-year program in 2009 that allows some admitted students to participate in nine months of university-sponsored service work at one of four international locations.
5. A gap year won't jeopardize college plans. Experiencing a gap year can be a blast. Who wouldn't want to monitor eagles in Swaziland or perform Shakespeare plays in England for a few months? Will students, who get these fantastic opportunities, ever want to buckle down and study again? While research is scant, anecdotal evidence suggests that students return to school more focused and mature and ready to start their college career.
