Metody hodnocení

Credit: - Two tests max. 30 points per test. - Bonus points (max. 10 points) for submission of practical tasks for the day of the exercise, or for solving complex computational problems. - Each student prepares a specific project rated up to 30 points. Submission of the project is necessary condition for credit. - The deadline of submission of the project is midterm week of the semester. For every further week, the maximum number of points to get for the project is reduced by 50 precent. - The project includes a user manual, withich describes the used procedures, algorithms. - To get credit, it is necessary to obtain total (2 tests + project) 55 points. Exam: - The writen exam takes 70 points. For the successful completion, at least 35 points are necessary. - The mark is determined by adding the points for the exam and points earned during the semester.
