**Критерії оцінювання результатів навчання:**Theoretical questions are intended to test students' skills in understanding the theoretical material. The answer should be complete and reasoned whenever possible. - The maximum number of marks (MCQs) for a question is awarded to a student who has fully covered the question; - 70-90 % of the MCQs - the question is generally covered, but there are minor inaccuracies or other shortcomings; - 50-70% of the marks - the question is not fully answered and/or there are significant errors; - 30-50 % of MCQs - an attempt is made to answer the question, but gross errors are made and/or the question is not covered in general. The same mark will be given if the student draws incorrect conclusions based on logical assumptions that contain correct reasoning; - 10-30 % of the marks - an unsuccessful attempt is made to answer the question, only some of the reasoning and/or formulas are correct; - 0 marks - none of the written formulas are relevant to the question, all the reasoning is incorrect or completely absent. The tasks are designed to test students' skills in practical solving of physical problems. Problems should be solved with as much explanation as possible and, if necessary, with a figure. - The maximum number of marks (MCQs) is awarded to a student who has completely solved the problem; - 70-90 % of the marks are awarded for a solved problem with minor inaccuracies; - 50-70 % of the marks - the student made a mistake(s) that affected the result, but the approach to the solution was correct; - 30-50 % of the MCQs - an attempt was made to solve the problem, but gross errors were made and the result was incorrect; - 10-30 % of the MCQs - an unsuccessful attempt to solve the problem was made and one or more correct formulas related to the problem were written down; - 0 marks - none of the formulas written down are relevant to the problem, or the student did not even attempt to solve the problem.
