Final examination and lab exercises (theoretical and programming). The mark of laboratory should be ≥ 5 for attendance in the final examinations. The mark of final examination should be ≥ 5 for successful course completion. The final mark is computed as follows: 0.3 * (Mark of Exercises) + 0.7 * (Mark of Examination). For each examination/exercises subject clearly specified evaluation criteria are given. The students can see their exam paper after the final examination and inspect their faults. The overall distribution of marks is announced on eClass, so that students can evaluate their performance.
