Requirements, evaluation and grading

Mid-term study requirements

Three tests will be written at pre-announced classes. Their duration is 45bminutes, their value is 50 points. They may contain problems and theoretical 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. . If the mid-term score does not exceed 50, the admission to the exam can be earned at a replacement test worth of 100 points, which reviews the entire semester's material, and in which previous points are not counted. Admission to the examination (Article 11 of the Exam Rules): a total score of 50 or more at the start of the examination period. The tests can only be replaced with a medical certificate. The medical certificate must be presented and the negotiation of the replacement test must begin no later than one week after recovery. Tests must be written using a pen; tests written using a pencil will not be awarded points. Only pocket calculators not suitable for storing or transmitting textual, visual and audio information may be used when writing the tests. During the tests, the student may only leave their seat after the final submission of the paper. During the tests headgear, scarves or other clothing suitable for concealing cheating devices may not be worn.

Exam requirements

The exam is written, its duration is 90 minutes and is worth 100 points. It may contain problems and theoretical 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. Exams must be written using pen; exams written using a pencil will not be awarded points. Only pocket calculators not suitable for storing or transmitting textual, visual and audio information may be used when writing the exams. During the exams, the student may only leave their seat after the final submission of the paper. During the exams headgear, scarves or other clothing suitable for concealing cheating devices may not be worn.

Generative AI usage

1st position: Use of GAI tools is not permitted for solving assignments. This means GAI tools cannot be used to complete formative or summative assessments, and using GAI constitutes academic misconduct. The use of AI tools for spelling and grammar checking does not fall under this prohibition.

Study aids, laboratory background

Video explanations regarding the parts of the material assigned for individual work. Documents, slides, tables published on Teams and/or Neptun Meet Street.
