Obtenção de frequência

Distributed evaluation with no final exam, with 2 tests (60% of final grade) and 5 lab activities with writen report (30%).
There's no test minimum grade; test average must be ≥ 8.5 val/20 val. No minimum grade for lab reports.
Theree will be no test repetition nor upgrading of lab reports.
To obtain course approval the final must be equal to or higher than 9.5 val.

Fórmula de cálculo da classificação final

NF = 0.6xT + 0.4xL

where:

NF - final grade
T - test average
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.
