Additional information on implementation and assessment Type (examination, oral, coursework, project):
• Written exam (solving computational problems)
• Completed homeworks (to intend the written exam)
Oral exam - theoretica part of exam (if necessarily, in the case of increase of the grade).
The student must finish each part of the exam (written examination and homework) with at least 50%. In the case that a student is offered the opportunity to take a written exam in the form of two midterm tests, each must be graded with at least 30% and both with an average of at least 50% to pass the written part of the exam.
