Eligibility for exams

According to FEUP's regulations.

Calculation formula of final grade

1) The student may choose between distributed evaluation or final exam.
2) If the student chooses distributed evaluation, the final grade will be the average of the classifications obtained in the 3 midterm exams.
3) If the student misses one of the midterm exams, or wants to improve the classification obtained in one of the midterm exams, he/she may, on the date of the 3rd midterm exam, choose to take the 3rd+1st or 3rd+2nd midterm exams, which will have a weight of 2/3 in the final grade.
4) The final grade of 20 will only be given to students that obtain the grade of 20.0 in all evaluation components.

Examinations or Special Assignments

Three mid-term exams of 90 minutes.

Internship work/project

Not applicable.

Special assessment (TE, DA, ...)

By final exam.

Classification improvement

By final exam.
