About the preparation of your stay: In order to prepare your stay, it is very probable that you look for information in the page Web of your university anfitriona. Well-taken care of Ten because the information is perhaps not updated, correct or completes. Several examples: your university anfitriona is not in center placed in Madrid but in the outskirts and not you DAS counts of it until you consult a plane or that you go there. It also can that your university anfitriona has its main faculties in Madrid but that other faculties are even placed in smaller cities outside Madrid and to 70 or 80 kilometers. If besides your main race you follow classes of languages perhaps as Chinese or Japanese, your university anfitriona requests that you pay to you the matriculation and that is legal because it does not comprise of your main race. Also it can happen that the university anfitriona implements a new race. In this case, the classes of the first course are only distributed but in the page Web usually they put the curriculum of the whole race.
That can cause problems if the subjects that interest to you are exclusively those of I second or third party (or more) because still they are not distributed. About the scholarships: The European Union grants a scholarship to all the students ERASMUS. But its amount is very low and it does not cover for anything the expenses of your stay. It hardly covers the rent with a month or at the most two months. For this reason, you must have another support financier. The students who receive a scholarship of their national state have much luck because not only they perceive this scholarship besides scholarship ERASMUS but also they receive a generous complement on the part of the European Union that allows them to cover all expenses if they live without excesses.
