Obtenção de frequência

- Assessment of Theoretical/Practical Component (NT) – exam or 2 interim tests;

- Evaluation of the laboratory component (NL):
The Laboratory Component is composed of works carried out in AutoCAD,
works of simulation of electrical schematics in CADeSimu and works of assembly of schematics (NL).

- Individual work assessment (NTi):
The individual work is composed by the elaboration of the installations diagrams for the use of an apartment, carried out in AutoCAD (NTi).

The curricular unit is evaluated according to the following components:

1. Average grade of the two tests or exam grade (NT);
2. Laboratory grade (NL);
3. Grade of individual work on electrical installations of an apartment (NTi);

Lab classes are mandatory.
The performance of individual work is mandatory.
The theoretical component is mandatory.

 

Fórmula de cálculo da classificação final

The final classification is calculated according to the following expression:

Final Grade = 0.6NT + 0.2NL + 0.2NTi


The minimum rating for any of the components (NT, NL, NTi) is 9.5.

Avaliação especial (TE, DA, ...)

The general formula for calculating the final classification is applied

Melhoria de classificação
