College is free!

Two things about higher education have become clear. First, your children need it more than ever to stay competitive -- and so might you, if you need to upgrade for a fast-changing job market. Second, the model colleges use to deliver that education is broken. Rising tuition, high student debt, and stingier funding for public colleges are making it more difficult for families to keep up. So it's hard not to get excited about this: Right now, for the unbeatable price of $0, Massachusetts Institute of Technology professor Anant Agarwal is teaching a class on circuits and electronics to thousands of people online -- no MIT application required. Harvard, Princeton, Michigan, and other top schools have also started open courses for everyone.
