We live in an era where geographical distance is no longer an issue when we want to study at Yale, Princeton or Johns Hopkins Universities.
There is a very new initiative - Coursera - to make available for free and for all what is called MOOCs (Massive Open Online Courses). The initiators have established quality alliances with 107 partners (Universities and other institutes) because they "believe in connecting people to a great education so that anyone around the world can learn without limits". They have put in place a nice platform for interactions with the teacher and other remote classmates. And they offer (for now) 557 courses in all the domains you could have thought of and not only in English (11 other languages are also represented)!. Currently there are 5.799.618 'Courserians' (a.k.a registered users on the website) and the figure is growing as you look at it (during the time I wrote this message, 26 more people just joined. Simply amazing!)
I am not part of the organization but I am making advocacy for it because I consider it is a high-quality resource. I have enrolled in 3 courses and based on my experience, this can bring a lot of added value through education. They also provide you with certificates provided that you respect some criteria/conditions.
I encourage you to have a look.
