Evaluation Methodology
Continuous evaluation:
The final grade (NFinal) is calculated considering the exams grades (NProvas) and individual coursework (NTrab.):
NFinal=0,75xNprovas+0,25xNtrab or only NProvas
Final grade: Written exam


Method of interaction
The theoretical concepts will be presented in classroom with the aid of audiovisual media. Worksheets will be resolved in class.
