The best of the best' college-level courses on CD, DVD, and Digital formats. Over 500 expertly-produced courses by professors chosen for their ability to teach and I have 50 of them. They are primarily science and history. They have been viewed once only. Each of these lectures would cost you $79 and I am asking $20. How can you beat that?
The single picture here is a picture of what the individual DVD looks like. This ordered from the Teaching Company would cost you $80.00. This one has never been opened or viewed.
