### Grading

No make-up exams will be given for missed tests. All the assignments should be turn in by the designated due date. To pass this course all the course requirements must be SATISFACTORILY completed > 30% of each problem set.

## What you Need to Pass

- Attend lessons. One missed +0 points. 2 missed 0 points, 3 missed 0 points, 4 and more is Fx.
- Project and exercise (mandatory, 50 points).
- Solve all homework problems (mandatory each one >=30%, 20 points)
- Pass final term (mandatory, 10 points) You will need to solve several problems discussed during lessons.
- Pass oral/written exam: (optional, +20 points) If you feel you are better, convince me !
- Summary
- Attendance = 0 or -100 (Fx)
- Homework = +30..9 or +8..0 (Fx)
- Project = +50..0
- Final term = +20..0
- Oral/written exam = +20..0

- Grades
- A = 92-100
- B = 84-91
- C = 76-83
- D = 68-75
- E = 60-67
