Requirements for awarding credit points

Students must perform all laboratory works and submit laboratory reports, answer to theoretical questions which are based on the background of the experiment, write 5 tests during the semester and write exam.

Description of the organization and tasks of students’ independent work

Preparation of laboratory reports - compilation and
systematization of chemical reactions, observation,
conclusions and experimental progress.

Criteria for Evaluating Learning Outcomes

It is necessary to write successfully all tests, i.e. no lower grade than 4 points. All laboratory reports must be checked. If the average mark of successful written tests is not lower than 7 points and all laboratory reports are checked, then the exam does not have to pass, i.e., an average grade is displayed.
