Obtenção de frequência

Throughout the semester students are submitted to three mini-tests, several open questions and kahoot questionnaires and perform extra-formative minitests.

• If the attendance to the Theoretical-Practical classes is less than 75 %, the student can only perform the theoretical component in Exam Season, that is, the student is excluded from the continuous evaluation process;

• The minimum score in each minitest may not be less than eight (8) values;

• It is only possible to recover the classification obtained in one of the minitests, and you can only recover this test on the date of the Normal Season exam. If you fail in two or more minitests, your theoretical evaluation will be sent to the examination;

• The score obtained in the Theoretical Examination cannot be less than 10 (ten) values;

• The average Laboratory Work (TL) cannot be less than ten (10) values.

Fórmula de cálculo da classificação final

The final grade (NF) in the discipline is obtained according to the formula,

      NF = 0.60 * AT + 0.40 * TL

• Theoretical Evaluation (TA) = 0.1 MTF + 0.4 MT + 0.1 Qopen;

• MTF - Training minitests (3);

• MT - Minitests (3);


• Qopen - Open questions submitted via moodle/Kahoot;

• Average Laboratory Work (TL);

Melhoria de classificação

The performance of examination tests for the purpose of improvement is subject to registration in the Academic Secretariat according to the current rules. The improvement of the score focuses solely and exclusively on the theoretical component of the evaluation (TA).
