Requirements:

Conditions of assessment:

Successful passing of two assessment written tests (in sum from both assessment tests minimum 50% points must be achieved). Obligatory and active attendance of all tutorials. It is necessary to participate in all laboratory work. Absences are acceptable for serious reasons only and must be apologized and replaced. It is possible to replace just two sessions. Students have to come in time. It is necessary for each laboratory session to work out a report in corresponding quality and hand it over in due time. For the attendance at each lab session, the student has to pass an entrance test at least for 60 %.

More detailed information can be found in the document “Organization of tutorials in physical chemistry” see below.

Course and Examination conditions:

The exam consists of written and oral part. Written part is in the form of a test in which the students will answer questions. The number of questions is from 5 up to 15. Some questions may be of higher value in evaluation than others e.g. those which include numerical tasks or require a more complex approach for the solution. Classification will correspond to percentage achievement according to a valid classification scale. In case the written exam is sufficient for classification, the oral exam can be omitted. After oral exam, the final grade will be given as the average of oral and written exams. If the result of any part is evaluated F, the result of the exam is automatically F and the previous rule of calculation does not apply.

Student has to pass a written test comprising the topics discussed during the lectures and tutorials, including assigned individual study. The exam is graded according to the ECTS scale, to pass the exam, the test must be evaluated at least at 50 %.

More detailed information can be found in “Instructions for exam in physical chemistry”. See below.
