Eligibility for exams

Participation in, at least, 70% of the classes held and in the study visits.

Calculation formula of final grade

Two tests during the semester, with a theoretical component (without consultation, 60 minutes, 2/3 of the final grade) and a practical component (limited consultation, 60 minutes, 1/3 of the final grade).
The weight of the result of 1st test in the final grade is 60%; the second test weights 40%.
In the appeal season, appeal of the total program, with theoretical and practical components, in the same conditions and with the same weights as in the tests.
The attendance and participation of the student will be considered for small adjustments (limit 1/20) in the final grade.

Special assessment (TE, DA, ...)

According to FEUP regulations, with rules similar to the ones of the improvement/final examination.

Classification improvement

According to FEUP regulations, simultaneously with improvement/final examination, with the same rules.
