Eligibility for exams

-Students will be admitted to final exams if they are enrolled in the course unit and if they:

1. Do not miss more classes than allowed by FEUP regulation.

2. Achieve a minimum grade of 6 (six) out of 20 in the continuous assessment component.

- Continuous assessment will be based on 1 midterm test which will last one hour and on the realization of 2 laboratory experiments, on dates to be announced early in the semester.

- Students who were admitted to exams in the 2021/2022 academic year do not need to attend classes and their continuous assessment grades will be maintained. However, they can choose to take the continuous assessment component again, but the grades of the previous year will not be taken into account. This decision is irreversible.

- Students who attended the laboratory classes in the 2021/2022 academic year do not need to attend these classes and their continuous assessment grades in this component will be maintained. However, they can choose to take the continuous assessment laboratory component again, but the grades of the previous year will not be taken into account. This decision is irreversible.

Calculation formula of final grade

CA - Continuous Assessment (0-20 points) 

CA = 0.5 T + 0.25 L1+0.25 L2, where
T - Midterm test grade (0-20 points)
L1 - Laboratory work 1 (0-20 points)
L2 - Laboratory work 2 (0-20 points)

FE - Final Exam (0-20 points)

FG - Final Grade (0-20 points)

If CA >= 6 then the student is admitted to final exams.

CA has a 40% weight and FE has a 60% weight of the FG.

FG=MAX(0.4*CA+0.6*FE, FE)

Examinations or Special Assignments

Not applicable.

Internship work/project

Not applicable.

Special assessment (TE, DA, ...)

- Students with a special status do not need to attend classes and take the continuous assessment component. Their final grade will be based on the grade achieved in the final exam. However, these students can choose to take the continuous assessment component. This decision is irreversible.

Classification improvement

Through the 2nd round Final Exam ("Exame final da época de recurso").

The Final Grade will be evaluated as follows:

FG = max (0.4*CA+0.6*FEN, FEN, 0.4*AD+0.6*EFR, EFR)

where FG is the Final Grade (from 0 to 20 points), CA is the Continuous Assessment grade (from 0 to 20 points), EFN is the 1st. round Final Exam ("Exame final de época normal") grade (from 0 to 20 points), and EFR is the 2nd. round Final Exam ("Exame final de época de recurso") grade (from 0 to 20 points).

Observations

- Besides attendance to classes, students should study around 6 hours per week for this course unit.

 - Any attempt of FRAUD during the continuous assessment means that students will not be admitted to exams.
