Grading

You may find your grades here.

Formula

Final Grade = M1 * 0.3 + M4 * 0.7

Mi = E * 0.4 + HW * 0.2 + Q * 0.2 + S * 0.2

• E - exam grade: rational number [0, 10] = sum of the grade for the oral and written parts, out of 5 each
• HW - homework grade: rational number [0, 10]
• Q - lecture quizzes grade: rational number [0, 10]
• S - seminar practice grade: rational number [0, 10]

rounding: each element in the formulae is rounded up

Plagiarism policy

If plagiarism is detected, the assessment element will be assigned a score of 0.

If the student is suspected of preparing the task not on his own, the teacher has the right to initiate additional verification or defense of this particular assessment element. Then such an assessment element will be graded based on the additional verification or the defense.
