Tests are mandatory. 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 = 0.6T + 0.3L + 0.1P

where:

NF - final grade
T - test average
L - report average
P  - research work grade

undelivered items count as zero in the calculation
