- For the final grade calculation, a grade equal to or greater than 3.5 for each exam, for practices and for the problems is necessary. - To pass the course, the final grade must be equal to or greater than 5. - For the exams, any type of electronic device is forbidden, only a SCIENTIFIC calculator (not programmable) is permitted. - 2nd call- Each exam will be retrieved separately. The practices cannot be retrieved. If the practices grade is less than 4 in the first call, in the second call they will be evaluated with an exam (30%). |
