Evaluation method |
Weight(%) | Retake | Minimum grade |
R1, R3 | Part I: Short-answer exam | 35 | Yes | 4 |
R1, R2, R3 | Part II: Long-answer exam | 50 | Yes | 4 |
R4 | Laboratory exam | 15 | No |
The final grade will be a weighted mean of the marks obtained in the exams corresponding to each part of the contents and the laboratory exam. The exams will take place along the course. The weighting is detailed in the above table. To pass the subject, the aforementioned mean must be equal to or greater than five. In addition, a minimum grade of four is required in parts I and II. If the latter requirement is not met and the weighted mean is equal to or greater than 5, the final grade will be 4.9.
There will be a retake exam in which the student will have the opportunity to improve one or more of the marks obtained in the two theory exams. If the new grades are higher than those previously obtained, the mean will be recalculated. There will not be a retake for the laboratory exam.
