Additional information
Method of calculating the final grade:

1. It is required to obtain at least 3.0 form both laboratory classes and the final exam.
2. The final mark is a mean of both laboratory and exam marks.
3. The final mark is calculated as indicated in the general rules of study at AGH
4. If the positive mark form laboratory and exam have been obtained in the first possible term and additionally a student had been active during lectures the final mark can be increased by 0.5.
