Your study program is subdivided in modules, which consist of one or more lectures or seminars, and which are coordinated in their themes and in the way the timetables are set. An overview of the current lectures and seminars of the Department of Mathematics can be viewed here. You must register for the courses in TUMonline. 

The modules which you require for your chosen maths program, can be seen in the relevant examinations regulations (Prüfungsordnung)
