Evaluation method
A minimal final grade of 47.5% is mandatory in this course. This final grade is the result of a theoric evaluation (2 tests ( 15% and 25%) and 7 quizzes ( 2%, 3%, 5%, 5%, 5% 5% e 5%)) , or final exam, and 30% form Lab evaluation ( 4 reports).
Students are required to have a minimum of 66.666% of class attendance to be admitted to the final exam. A minimal classification of 40% is mandatory for the 2nd test A minimal final theoric grade of 47.5% is mandatory.
