20.  Forms of assessment Written exam: two partial exams (120 min each) or a final written exam (120 min). The student should prepare the planned homework and project assignments and submit them according to the published dynamics on the website for the course. Oral exam: for students who have passed the partial exams or passed the final written exam and completed the planned homework and project assignments, a final oral exam can be conducted (duration 60 minutes). The final grade is determined by the points obtained from the exams, homework and project assignments according to the respective weight coefficients. During the exam it is allowed to use the literature on the subject in printed form. The use of a calculator is allowed, but the use of mobile phones, tablets or similar electronic devices is not allowed.
