Continuous assessment without final exam. Maximum allowed number of absences: 1/4 of the total number of classes; 1/3 of laboratory experiments.
Practical lab mark:
NLAB = 0.50 x NTP + 0.50 x NAP
where NTP is the average grade of all 6 practical laborations and NAP is the individual lab assessment mark
The final grade, NF, is calculated according to:
NF = 0.75 x NLAB + 0.25 x NTIC
where NTIC is the grade on the ICT part.
Approval requires NTP ≥ 10, NAP ≥ 8 and NTIC ≥ 8.
