Evaluation Methodology
The theoretical assessment (TA) is conducted through a written test, during the various official assessment periods.
The practical assessment (PA) is obtained by completing all practical assignments and their respective reports.
The oral assessment (OA) is obtained by submitting a written thematic assignment, with an oral presentation, and by demonstrating interest and participation in class.
The final grade (FG) is obtained by applying the following formula:
FG=(0,5xTA)+(0,25xAP)+(0,25xAO)
Minimum final passing grade of 10.
