Online Classes
Online Classes, sometimes called Open Courseware, are classes taught in Universities that have been put online for anyone to access. They vary in quality and resources provided, and they do not grant course credit at any of the involved universities, but they are great resources, especially for gifted kids who are ready for college materials but maybe not for moving out and going to college.
