Have you heard of Coursera? If not, you have to check it out. It's a website that offers free online classes from top universities throughout the world. Some classes have upward of 20,000 students at a time. I'm currently enrolled in a class from Duke University about philosophy and constructing arguments. You don't get college credit, but many courses offer a completion certificate. From their website: "we hope to give everyone access to the world-class education that has so far been available only to a select few. We want to empower people with education that will improve their lives, the lives of their families, and the communities they live in."
