Evaluation Type

Distributed evaluation with final exam

Assessment Components

Designation	Weight (%)
Exame	65,00
Teste	35,00
Total:	100,00

Eligibility for exams

According to the general rules of FEUP.

Calculation formula of final grade

There are 2 evaluation moments:
First evaluation moment: "Mid-term Test", involving the assessment of Chapters 1 to 5;
Second evaluarion moment: Final Exame (Normal and/or Repetition), involving all subjects of the Biological Engineering course.

The Final Classification is the best of the two following models:
Model A: Weighed average of the Mid-Term test (35%) and the Final Exam (65%); or:
Model B: Final Exam (100%)

In  both Assessment Models, the Final Exam includes all the subjects of the course.

Examinations or Special Assignments

The first test is scheduled for the end of March or in April.
The dates for the Final Exams are defined according to  FEUP's exams calendar.

Classification improvement

Final grade improvement can be obtained in the repeating exam (Juyly).
 

Observations

For approval, the final grade must be equal to or higher than 10.
