UNED (National University of Distance Education) is a very special university. You don’t have to go to classes, it’s a “distance” university. There is the online platform where there is a forum to ask questions to teachers and to discuss with other “classmates”, and you get orientation on the books and notes you should prepare. Then, for the exams, you can choose where to take them. In Spain there are many places to take them (almost in every city), and in Europe in each capital at least. In the rest of the world, you can take your exams in several capitals.
The problem with UNED is that sometimes the materials are a bit outdated and it’s hard to communicate with certain teachers. I hope this evolves little by little to have a more dynamic and modern university not only in its concept but also in the contents and the rest of the administration.
