SuperC is located right next to the Hauptgebäude, the main building of the RWTH, right in the heart of the university district. The landmark building can easily be recognized by its shape (not really a C, that would have been too easy as well).
Study rooms are located in the "Sparkassen Forum", in the basement of the SuperC which can be accessed through the basement doors in front of it or through the stairs and escalators within the building.
The International Office Service Center is on the third floor in room 329.
SuperC is also the place where permanent students enrol.
