Obtenção de frequência

The student has to deliver a prototype (25%), a written report (25%), and carry out a discussion about these two elements (50%) with the course teacher, on the dates agreed at the beginning of the course.


Otherwise, the assessment consists of three elements:
• Evaluation of the laboratory/workshop prototype (25%)
• Evaluation of the report or presentation related to the development of the prototype (25%)
• Oral discussion of the written report of the laboratory prototype (50%)

- The minimum grade for each of the assessment elements is 10 (ten). If any element is missing by the agreed delivery date at the beginning of the semester, the student is automatically disapproved.

- Since the discipline's methodology is based on a continuous assessment model, the student cannot be submitted to an exam.

Fórmula de cálculo da classificação final

• Evaluation of the laboratory/workshop prototype (25%)
• Evaluation of the report or presentation related to the development of the prototype (25%)
• Oral discussion of the written report of the laboratory prototype (50%)
