Assessment methods and criteria: Methods of assessing the level of achievement of educational outcomes of education seekers are carried out with the help of an oral survey in lectures and practical classes.
Assessment of knowledge is provided by current control and semester examination control.
Current control - preparation and implementation of practical works; preparation and execution of graphic and calculation works.
Examination control is carried out during the session in written and oral form.
Current monitoring of practical classes is carried out with the aim of identifying the student's readiness for classes in the following forms:
• a selective oral survey before the start of classes;
• assessment of the student's activity in the process of classes, submitted proposals, original solutions, clarifications and definitions, additions to previous answers, etc.
Examination control is carried out in the form of a written and oral survey and/or test control.
The final control is carried out based on the results of the current control and semester examination control.
Критерії оцінювання результатів навчання: Semester control - exam
Current control (30%): written reports on calculation works, oral examination.
Practical classes - 30 points
Final control (70 %, control measure): written-oral form (70%)
Written component – 60 points
Oral component – 10 points
Порядок та критерії виставляння балів та оцінок: Points for current and exam control are assigned as a percentage of the maximum score for the educational material of the component based on the following criteria for evaluating the knowledge and skills of the student:

87–80% – awarded for knowledge of the educational material of the component above the average level, including calculations, reasoned answers to the questions asked (a small number of inaccuracies are possible), the ability to apply theoretical provisions when solving practical problems;
79–71% – a generally correct understanding of the educational material of the component, including calculations, and reasoned answers to the questions, which, however, contain certain (insignificant) shortcomings, is awarded for the ability to apply theoretical provisions when solving practical problems;
70–61% – awarded for mediocre knowledge of the educational material of the component, weak application of theoretical provisions when solving practical problems;
60–50% – awarded for weak knowledge of the educational material of the component, for weak application of theoretical provisions when solving practical problems;
