You can access them via the Internet. There are all the lectures videoed and posted. For free. For real.
Biology, history, philosophy, English and many others.
Including a whole course on Hemingway, Faulkner and Fitzgerald.
Oh my fucking god.
I can't believe how lucky kids are these days to have this type of access. It is mind-blowing. Want to round out your course? Jump online and watch some of the best lecturers in America doing their thing.
It is extraordinary.
