Several major universities offer select courses for free through various venues, including iTunes-U
. They're available via video and/or pod casts taken from previous semesters, some quite recent. I've taken advantage of several in the past both as an extra study tool for my regular coursework, and even just for pleasure. In general, I've found them to be excellent and wouldn't hesitate to recommend.
Coursera may be a step up from this because they have a community and a Q&A forum, but you might also want to check out the Open Courseware Consortium
. They too have a community, but offer thousands of courses from universities all over the world, and many are available in several languages.
Enjoy the class on Fantasy and Science Fiction, it sounds very interesting.
