Qualification
|
Laboratory practice |
A1 A2 A13 A23 B2 B3 B5 B6 B7 B9 C1 C2 C3 C4 C5 C6 |
Students must systematically attend practices. The proposed activities have to be done along the practical sessions, in order to be revised and evaluated by the teacher. The practices that aren’t developed during the practical classes, and periodically revised by the teacher will not be considered in the qualification.
The evaluation process of the laboratory lessons includes a two hour practice session, where the student solves with the computer the problems proposed by the teacher, individually.

Supervised projects |
A1 A2 A13 A23 B2 B3 B5 B6 B7 B9 C1 C2 C3 C4 C5 C6 |
The projects include the theoretical and practical contents of the course. They are to be done individually. The projects will be developed during the practical sessions along the course and completed at home on the student personal work hours. The tasks will be followed and revised during the practical lessons. If the projects aren’t matured during the practical classes, nor periodically revised by the teacher, will not be considered in the qualification. |

Assessment comments |
The student, whose face-to-face work throughout the four-month period is not sufficient for evaluation, will be able to perform an objective test which allow evaluation and qualification.
