• Registration: t.b.a.
• Inspection/Review: t.b.a.
• WRITTEN Reexam on t.b.a
• Inspection/Review of Reexam t.b.a.

Allowed Material for the exam

Regulations

The exam takes place on t.b.a. Make sure you are in place on time. As the lecture hall is reserved from t.b.a., and as we have to leave at t.b.a., there's no chance to wait for late arrivals. A handwritten sheet of paper (size A4, front and back page) may be used during the exam as mnemonic as well as the MPI operation reference distributed during the tutorials. No other material besides dictionaries is allowed.

Please study your examination regulations. Students in most disciplines have to register for the exams throughout the semester via TumOnline.

Students that did not pass the exam or did not participate and still need the credits should contact Prof. Thomas Huckle for an appointment as soon as possible. In this case, the appointment always is the second try, i.e. if you do not take part in the exam, it is a failed try.
