Eligibility for exams

Admission to exam:
a) Attend to 75% of theoretical-practical classes, according to Article 6 of the Specific Rules for FEUP's Students Assessment;
b) Attend to at least one of the two tests with minimal classification of 5,5 out of 20.

Calculation formula of final grade

The student must attend to two written exams, with the duration of 1,5 hours each. Each exam comprises two different parts: a theoretical part, which worth 20% of the final mark and a theoretical-practical part which worth 80% of the final mark. Final mark will be based on the average grade of the two exams.
Exams are scheduled for these dates: 1st written exam: December 2020; 2nd written exam: February 2021.
According to Article 4 of General Evaluation Rules of FEUP, a student in order to pass the course must earn a grade of five point five out of twenty or better in each of the exams.

At the end of the semester students will be able to attend a new exam in order to improve their final grade. This exam may either only test a part of the program, or the whole program. Only students who got admission to exam can attend this exam.
Students who have passed the end of the evaluation process
Distributed and intend to carry out, to improve the classification obtained, the whole program revaluation evidence (in appeal) should make their registration in Academic Services of FEUP.
Date of the exam: February 2021.

During the evaluation tests are not allowed to consult any type of mobile phones, calculators and microcomputers.

Examinations or Special Assignments

Not applicable.

Special assessment (TE, DA, ...)

An exam at the special season, according to items 8.1, 8.3 c) and 8.4 c) in Article 8 of the Specific Rules for FEUP's Students Assessment.

Classification improvement

Classification improvement will exclusively be the result of the written exam according to Article 11 of the Specific Rules for FEUP's Students Assessment.
