Joe I take free college courses online from Coursera. This is from their website-
"Coursera is an education company that partners with the top universities and organizations in the world to offer courses online for anyone to take, for free. Our technology enables our partners to teach millions of students rather than hundreds."

I am currently taking a class called "The Camera Never Lies". There are many classes starting soon. It may help pass the time. Hope this is helpful to you, take care.
