Can I obtain a university-level diploma through self-instruction?

Yes, Open University allows you to follow individual courses, short programmes or to embark on a fully fledged university degree.

When you study at the Open University you are not tied to fixed times or a specific study location. You will be offered the programme of your choice in self-instruction modules which you can study where and whenever you like. To a large degree, you can even set your own study pace. 

The Open University also has a study centre in Brussels:
