Evaluation method
2 tests (or exam) yielding TG grade, and project yielding PG, for a final grade (FG) given by
FG = 0.7*TG + 0.3*PG.
For approval, both FG>=10 and TG>=9 are required.
Project consists of a group (of 3 students) assignment (including oral presentation) and of an individual evaluation report of another group''s project.
