I am taking some courses over at Saylor.org (spelled just like that.) At the moment, it’s Political Science…which is imposing because there happens to be a huge amount of reading required, right off the bat. You have numerous articles, of varying length, then a 29 page article to read and an hours lecture before being hurled into several more lengthy articles. However, despite all of the time invested, you do learn something, and I’ve also come to really appreciate how they have put together their website. It’s based on any normal type of professional, tuition-paid Universities offerings, including electives.
