The experience isn't exactly like taking an actual course. For one, you won't be awarded any credits, but considering it's all online and free, it seems a fair trade. You may not have access to everything from the class, but that's not really the point — as Money Magazine's Pat Regnier might tell you. He downloaded Berkeley's American economic history course on iTunes last year and a Yale professor's lecture series on the Civil War.
He wasn't seeking a secondary degree, but the lectures satisfied the urge to sharpen his intellect, without shelling out cash for grad school or a costly MBA. Just check out iTunes, Academic Earth, or OER Commons to find out what's available. So, what do you think? Would you take the time to give your intellect a boost with a little free online education?
