  2. All but one problem sets are solved satisfiably and at least two problem sets are solved successfully.

It is allowed to work in groups up to three students. We highly recommend to work in groups.

Final Grade-Bonus:

  •  A bonus of 1/3 is gained when

    • all problem sets are satisfiable solved and at least three of them are successfully solved, and
    • a solution is presented in front of class

  •  A bonus of 2/3 is gained when

    • at most one problem set is only satisfiable solved and all others are successfully solved, and
    • a solution is presented in front of class

The bonus can only be used to improve the final grade of the exam, when the exam itself is passed.
