## Kryteria oceniania

Assessment based on a written exam, tests carried out during the semester and activity during tutorials.

Detailed rules for passing the winter semester:

1. The final grade of the course is calculated on the basis of the sum of points obtained during the semester (max. 100p). Points are granted for tutorials (max 20p), for two joint mid-term exams during the semester (max 15 + 15 = 30p) and for the exam after the end of the semester (max 50p). Only those who have received at least 15points from the exam can receive a positive final grade.

2. Points for tutorials are obtained during short tests carried out in particular groups and for the activity during tutorials. During the semester there will be 8 short tests (every two weeks, during tutorials) checking knowledge of the current material. For each

test max. 2p can be obtained. Points for activity (max 4p in each semester) are awarded by the tutor according to his

own assessment.

3. Joint mid-term examstests (carried out apart from tutorials) consist in solving a number of problems from the materials taught during previous lectures and tutorials.

4. After completing the course (before the examination session), the student receives the grade from the exercises, calculated on the basis of the sum of points obtained during tutorials and joint mid-term exams (max 20 + 30 = 50p), according to the following scale: sufficient = 20p, sufficient + = 25p, good = 30p, good

+ = 35p, very good = 40p, very good + = 45p.

5. In order to take the exam, the student must complete the tutorials, i.e. Obtain at least sufficient grade for the tutorials.

6. The final exam is written and consists in solving a certain number of problems covering the whole material taught during the semester both during lectures and

tutorials. The rules for calculating the final grade are the same in each of the two terms of the exam.

7. In case of failing to pass the tutorials, the student has the opportunity to pass the correction test (the form is decided by the tutor. The student who passes the correction test, may take the final exam during the second term, however with the same number of points credited for tutorials (excluding the result of the correction test).
