The 25 Best Places To Take Free Online Computer Science Classes

These days, computers dominate our lives, providing the platform by which we work, play, and communicate with others around the world. As such, knowing how to work with and engineer these often quite complicated systems is a pretty solid skill to have in the modern workforce.

While a college degree is the most direct route to a career in computer science, students can start building their skills for free with some of the great resources offered on the web. We’ve listed just a few of the best sites for free computer education here, offering lessons in everything from programming to theory for students to take in whenever and wherever they like.
