Eligibility for exams

Miss less than 1/4 of the PL classes.
Accomplish successfully 2/3 of the lab works.
Positive grade (≥ 9,5) in PL classes.

Calculation formula of final grade

The assessment of knowledge will be done through a mandatory final exam and by the student's performance in the practical classes. The final grade will be calculated by: 0.70 x exam mark + 0.30 x mark practice

The student can dismiss the final exam by performing two tests (T1, T2) throughout the semester, provided that the final grade calculated (according to 1) from the arithmetic mean of both tests and the practical grade, is positive. Performing these tests is optional.

Special assessment (TE, DA, ...)

The student has to perform a practical exam for the obtention of the PL grade. A positive classification is mandatory for admission to the final exam.
The final mark is calculated in the same way as for the other students.

Classification improvement

Only the grade of the exam is subject to improvemnet.
