The module is passed by passing an oral examination covering the topics of all attended courses. To be admitted to the exam, students must actively participate in the problem sessions (including the solution of homework problems) and present a scientific talk in the seminar course. The grade given for the module is equal to the grade of the oral examination.

Problem Class
rules a continuous and independent dealing with the homework problems is strongly recommended
homework problems handed out every Tuesday in the Problem Class and can as well be downloaded as pdf
  solutions can be handed over for correction on the following Monday
discussion Tuesdays in the problem class
