Oral examination April 5th + Repetitorium on March 29th

Dear students,

as announced by Mr. Kaumanns on last Friday, due to the registration numbers, this years exam will take place as oral examination on the afternoon of Wednesday, April 5th between 2 pm and 5 pm in room S3|21/303.

I set up a time schedule in moodle. Two students will be examined at the same time, so please choose one of the empty slots and register in the schedule segment until end of February. Each examination will take approximately 45 minutes. Afterwards we discuss the grade and call you back in. Therefore we plan with 1 hour slots.

As additional preparation i will give a short course review / repetitorium on Wednesday, March 29th at 1:00 pm digitally via zoom (login data in moodle)

Best regards and good luck with your exams and preparations
