My free time in Universidad Autonoma de Madrid
At the beginning of your mobility, the university will let you choose your courses. You have a lot of choices: I was in 3rd year and I could choose courses from 2nd, 3rd, 4th year. Register for classes as soon as possible !!!
1) You will have more choices
2) You will have the possibility to gather your courses on 3 or 4 days to have a long week-end
3) You'll able to choose course only in the morning so you can work in the afternoon if you want.
