You can find the courses here.
Note: Bonn and Cologne have an established cooperation. Students from Cologne taking classes in Bonn must not register as “kleine Zweithörer” at Bonn University. Students only need to contact the professors teaching the classes they intend to take. For the Politics Module, students may email Holger Janusch (hjanusch(at)uni-bonn.de), and for the Economics Module, Sine Kontbay Busun (skontbay(at)uni-bonn.de) is responsible. Students then participate in the courses in Bonn, do the required exam and get a certificate which will be recognized for the MA NAS in Cologne.
Students complete either one of these modules, Politics or Economics, in toto in Bonn over the course of two semesters, instead of studying module 3: Postcolonial Studies here in Cologne.
