The University of Stuttgart is one of Germanys largest technical universities. They have a strong focus on engineering subjects, specifically, the Bachelor of Aerospace and Aeronautical Engineering is a unique opportunity. Close cooperations with the surrounding companies really shape the classes, there are many guest lectures by these companies.
The day to day life is quite relaxed, both the outer and the central campuses offer a nice green view in the summer, sadly the winter makes the university quite grey. The on-site cafeterias offer a good variety of food that gets a bit boring after a year or two but there is always an edible option. The libraries and study rooms have nice long opening times and there is always someone around to talk to.
