Forms of Teaching


Lectures are delivered to groups of approximately 120 students using electronic presentations, detailed derivations on the blackboard and demonstration experiments.


Written mid-term exam and the final exam consist of four excercises and a number of multiple choice questions.

Laboratory Work

Students perform six laboratory experiments, carry out the analisys of the measured data and write the final report for each experiment.


Lectures are supported by demonstration experiments that illustrate the concepts of physics. Approximately 30 mins / week.


At least once a week each professor is available to the students for consultations.


During the semester homework assignments are delivered to the students through the e-learning system Merlin (Moodle).

Other Forms of Group and Self Study

In approximately 4 terms per semester additional exercise-solving skills are demonstrated by assistants.
