"Pre-university students ages 13 to 17 are invited to take part in Google Code-in, our contest introducing young minds to the world of open source. With a wide variety of bite-sized tasks, it's easy for beginners to jump in and get started no matter what skills you have. Mentors from our participating organizations are available to lend a helping hand as you learn what it's like to work on an open source project.
Want to work with a real open source software organization while earning cool prizes? Try your hand at Google Code-in. The contest begins on December 7th."
