For longer counseling interviews we recommend appointments aside from the consulting hours. This way we can focus on your questions without disturbance.

If you cannot find a suitable date, if technical problems prevent you from booking an appointment or if you are not a student of RWTH Aachen University, please send us an Email with at least three possible dates. We will answer your request soon.
