Obtenção de frequência
CONTINUOUS ASSESSMENT - Intermediate tests (2 tests) - 60%
- Lab work with written report (7 activities) - 20%
- Presentation of a bibliographic research work - 20%
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.
FINAL EXAMINATION- Final exam - 80%
- Lab work with written report (7 activities) - 20%
Fórmula de cálculo da classificação final
CONTINUOUS ASSESSMENT
NF = 0.6T + 0.2L + 0.2Pwhere:
NF - final grade
T - test average
L - report average
P - research work grade
(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)
