Obtenção de frequência

The minimum grade in continuous assessment by tests is 8 values ​​in any of the tests.
In situations where the faculty considers it necessary, final grades higher than 16 may be defended in oral exams. If the student does not attend these oral exams, his final classification will be 16 values.

(In the evaluation by final exam or tests, questions related to the laboratory component of the UC are foreseen)
Once approved in continuous assessment, the student will only be able to improve the grade during the appeal period. Attendance and approval in the laboratory component (execution of all work, delivery of results and reports) is mandatory for approval in the UC.

Rules for conducting tests:
• When requested, it is mandatory to present an identification document during the tests.
• Only written tests in EST Setúbal test/exam notebooks are accepted.
• Leaving the room can only take place 30 minutes after the start of the test/exam and implies the final delivery of the test, and the delay in entry cannot, under any circumstances, exceed 15 minutes.
• During the tests, calculators with graphic or alphanumeric capabilities may only be used if the teacher authorizes it.
• During the tests, the handling or display of cell phones (which must be turned off) and other electronic equipment is not allowed, and the use of any of this type of equipment is a reason for cancellation of the test.

Fórmula de cálculo da classificação final

The final grade is calculated according to the following formula:
NF=0.7*EF+0.2*LAB+0.1*DSA;
EF- average classification of the 2 tests or the classification in the final exam;

LAB- laboratory classification (minimum 10 values);

DSA- Classroom performance (includes lab).

In the case of assessment by exam, the grade of the EF component corresponds to the classification obtained in this test, and, as mentioned, the attendance and approval in the laboratory component is mandatory for approval in the UC.

Improved final distributed ranking
The student can improve his final grade obtained by continuous assessment by taking the exam.
