Calculation formula of final grade

The evaluation of this course can be done in two tests during the classes and in a final exam.

Must have 7,5/20 as minimum mark in the exame. The final mark (CF) is calculated by:

CF = 0,3 Tests + 0,7 Final Exam

Examinations or Special Assignments

Not applicable

Special assessment (TE, DA, ...)

Final exam, according to the calendar prepared by the direction of MIEQ.
