Requirements, evaluation, grading:
Mid-term study requirements:
Depending on the evolution of the emergency situation and the decisions/recommendations of the faculty committee for method of assessment, changes may be possible in this point. The exam is written, lasts 90 minutes and is worth 100 points. It may contain questions regarding the material presented in the lectures and the material given for individual work, and regarding the exercise lessons, including theoretical questions and calculation problems requiring textual descriptions, drawings. Preparation for the theoretical part is aided by the examination thematics, which is published at the end of the semester. The following may be used in the examination: writing utensils, pocket calculators not suitable for storing textual information and a handwritten (not photocopied or printed) one-sided A5 format sheet of formulae written in blue pen. Half of the points above 50 obtained during the period of study will be added to the examination score. The examination mark will be determined in accordance with the table in § 11(2) of the Exam Rules.
Exam requirements:
