Off to college
By Bankrate.com

Whether you plan to live on campus or off, money tends to slip quickly through your bank account once you're in college. A fun night out with friends, decorating your dorm room, tickets to concerts, college textbooks and other academic expenses can drain your finances quicker than you can download an MP3.

Unfortunately, for many college students, debt is a fact of life. But student loans and big credit card balances are not mandatory graduation requirements. You can enjoy everything that college life has to offer as long as you take control. All it takes is a plan of action for your spending.
