Eligibility for exams
In this course it is mandatory to comply with the attendance in classes.
The students must attend a minimum of 75% of the total number of classes and to obtain a positive mark in written works done during the semester.
Calculation formula of final grade
Final exam – individual evaluation - 40%: lowest mark 9,5/20 (round off to decimals)
Written Works performed in the context of classes: 25%: oral presentations, problems resolutions, homeworks. Lowest mark 9.5/20 (round off to decimals).
Presentation of accreditation project: 35%: lowest mark 8.0/20 (round off to decimals)
Final evaluation: 40% Exam + 25% written works + 35% accreditation project
