Homework policy

  • To get a certificate for the tutorial you need to obtain an average grade of 60% on the homework assignments in both halves of the semester.
  • Homework assignments are due weekly. They may be turned in at the beginning of the tutorial or left in the letter box of Rene Zander (MA 701, Frau J. Downes) before that time.
