Each year, high school students across the U.S. march through campuses on guided tours, pore over course catalogs, and frantically check mailboxes and inboxes for letters granting them admission to the next phase of life: college.

Most are facing significant financial questions. Research consistently demonstrates that college graduates earn more than their peers without degrees. According to the Bureau of Labor Statistics, Americans with a bachelor's degree have median weekly earnings of $1,173, compared with just $712 a week for those who have a high school diploma. Still, experts urge high school students to think carefully before taking on significant amounts of debt to finance a college degree.
