Obtenção de frequência

Continuous assessment consists of - test and written work - and ten laboratory assignments. The evaluation can also be done through final exam on all the subjects taught.

Test on partial contents and written work, with a weight of 70% in the final classification, and students can not have an average grade lower than 9.5 points.
Laboratory reports (in groups), focusing on materials testing, with a weight of 30% in the final classification.
The final classification of the continuous assessment is obtained as follows:
Final mark= 70% average grade (Test + written work) + 30% Laboratory Note.

Final exam with a weight of 100%, students cannot have a grade lower than 9.5.

Fórmula de cálculo da classificação final

NF = 0.TxT + 0.3xL

where:

NF - final grade
T - test average+ work
L : report average

undelivered items count as zero in the calculation

Provas e trabalhos especiais

Working Students, Federated Athletes, Student's Unions Leaders  and Students under the Law of Religious Freedom must contact the  professor until the end of the second week to present their relevant specificities, as provided for in the respective diplomas.
