As a high school dropout, education has always been a fascination for me. Most people are not aware that a very powerful free resource exists within itunes called itunesU.
In fact you can download entire course lecture audio and sometimes video for any course you choose. I am a bit of a psychology buff so I started there. I have since done my MBA, marketing degree, economics and no shortage of scattered interesting courses all on my ipod either in my car or at home.
Of course I don’t have a degree to back it up but who cares?
Here is a short list of tracks I recommend.
