Approval in the subject can be obtained by continuous assessment or by final exam.
Continuous assessment and final assessment include a mandatory laboratory component and a theoretical component.
The laboratory component consists of:
1) Execution of the 5 laboratory works with delivery of the respective report by email and Moodle up to two weeks after the respective laboratory class.
2) Execution of a mini-laboratory project with delivery of the respective report and software until 24 June, with oral discussion in the same class.

The theoretical component consists of carrying out two interim tests (T1 and T2) on the defined dates.

The minimum grade in the continuous assessment tests (T1 and T2) is 9.5 values. The minimum grade for laboratory work (Lab1 and Lab2) is 9.5 values.

Assessment by final exam consists of the regular or appeal period exam. Those who do not pass the theoretical component of the continuous assessment may recover in the regular or appeal period exam. Those who pass the theoretical component of continuous assessment will be able to improve their grade in the exam at the time of appeal. The minimum grade for the regular season exam and appeal exam is 9.5 values.

All exams and interim tests are written and performed individually.

If the teacher responsible for the subject considers it necessary, for final grades above 16 or for other doubts regarding the grade obtained by the student, oral tests may be carried out. If the student does not attend the oral test, in the case of grades>=16, his final classification will be 16 values.

Fórmula de cálculo da classificação final

The continuous assessment grade (N) is calculated according to the following formula:
N = 0.5*T + 0.25*L1 + 0.25*L2, with T>= 9.5 values, L1 and L2 >= 9.5 values,

where:

T: Average of the scores of the two interim tests (T1 and T2) or the score of the regular exam;
L1: Grade of the 5 lab works (Lab#1 and Lab#2);
L2: LabView mini-project note.
