Teaching method

In 2020/21, due to the SARS Covid-19 pandemic, all classes will be online and exclusivelly in Portuguese.

Any non-Portuguese student should contact the Professors if (s)he requires any assistance. 

Basic concepts will be introduced in lectures ("aulas teóricas") and problems will be solved in problem solving classes ("Aulas práticas").

Moodle e-learning platform will be used to carry out weekly learning activities.

Evaluation method

For full details please access the pdf file in Documentação de Apoio > Outros

For further information, you should contact Prof. Ruy Costa, ryac@fct.unl.pt .

Students should attend at least 2/3 of the practical lessons.There are 2 Tests during the semester and one Exam afterwards.
