Evaluation Methodology
In the periods of frequency and exams, the evaluation will be carried out using written tests without consultation. The tests are composed of two independent parts: theoretical component and practical-laboratory component.
The final classification in each assessment period is obtained by the formula: Final classification = T x 0.5 + PL x 0.5, where: T - classification of the theoretical component obtained in the frequency period by the arithmetic mean of the theoretical tests and in periods examination by theoretical test; PL - classification of the practica-laboratorial component obtained in the frequency period by the arithmetic mean of the practical-laboratory tests and in exam periods by the practical-laboratorial tests.
The theoretical and practical-laboratory components have a minimum score of 7.5 values for approval of the curricular unit, and are exempt from examination with a score equal to or greater than 10 values.
