Assessment comments |
The evaluation will be made on the final exam and on the written reports of the practices. Evaluation in the case of part-time students: the same as in the general case. At the second opportunity, only the final exam will be assessed. The practical grade will be that obtained during the course through the continuous evaluation of the student's work. According to article 14, paragraph 4, of the UDC evaluation regulations, the copied practices will be void, both the original and the copy, and will suppose a zero in the practice in question. |
