Obtenção de frequência
Distributed evaluation with no final exam, with 2 tests (70% of final grade) and 7 lab activities with writen report (30%, only the 6 better grades are considered).
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
CONTINUOUS ASSESSMENT
NF = 0.7T + 0.3L
where:
NF - final grade
T - test average
L - reports average
(undelivered items count as zero in the grade calculation)
FINAL EXAMINATION
NF = 0.8E + 0.2L where:
NF - final grade
E - exam grade
L - reports average
(undelivered items count as zero in the grade 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 by the end of the second week of the semester, to present their relevant specificities, as provided for in the respective diplomas.
