Have you experimented with Coursera yet? Did you know that the Network is involved?
Coursera offers individuals the opportunity to take courses through their online education platform for free. Sometimes a small fee (optional) is charged in order to be granted a verified or specialized certificate. Learners from all over the world can participate, working at their own schedules, and interacting through online forums. Check out the video where Linda and Judy describe the course in more detail.
