The IESEG is a business school in Paris and Lille, home to diverse, dedicated and committed students, highly motivated and open-minded teachers, an open and accessible administrative department, and a large network of The new entrants. The campus of Paris, even if it is in the underground of the Grande Arche of La Défense, is a campus very high-tech and very diversified in nationalities, where one makes friends easily. For its part, the campus of Lille is located in a very busy, very diversified student area and close to several places of catering. Student life in Lille is, in my opinion, the best in France, because of the strong presence of young students from every corner of the world. For my part, after having spent one year in each of the IESEG campuses, I strongly advise that of Lille. What I enjoyed most at the IESEG is the fact that the campuses remain open 24/7 to students wishing to revise. On the other hand, with regard to the choice of subjects, some students are excluded from certain courses in the limited number of places and this can be very annoying.
