The amount of free university level courses on the internet is raising by the hour. It is amazing to have the opportunity to receive intimate lessons from the best universities in the world and by the most highly respected professors in the business.
My favourite free university so far is udacity. The way the courses are structured is ideal for students with time constraints. Each nano-lesson is offered in a small video (between 2 and 5 minutes), and the interactivity that it provides makes you exercise your mind in such a level that the key concepts are really learnt.
I foresee a future in which professors simply will be there to interact with the students and motivate them, but the real lectures and contents will be delivered on the internet only by the best of the best.
The power of internet is limitless. Thank you ARPA.
