Written exam.

The written exam covers the elaboration of 10 problems.

To facilitate the evaluation, the following approximation is applied.

The maximum rating for the exam is 100 points.

Rating 2 (failure): result < 40 points

Rating 3 (satisfactory): 40 ≤ result < 50 points

Rating 3.5 (satisfactory plus): 50 ≤ result < 60 points

Rating 4 (good): 60 ≤ result < 70 points

Rating 4.5 (good plus): 70 ≤ result of < 80 points

Rating 5 (very good): 80 ≤ result ≤ 100 points
