I strongly recommend this university because it is one of the best in the community of Madrid in social sciences. It offers a huge variety of degrees, international programs to study abroad, experts in research, job opportunities, activities, huge varieties of programs etc. It also should encourage us the good level of the students in this university, making the environment competitive and pleasant to learn. As a downside, I think the quality of teaching can be improved in some courses to put the teaching part at the same level as the research part.
If you study anything related to social sciences, forget about any other university of Madrid and come to Uc3m.
