Evaluation method
The approval in the Curricular Unit is obtained with a grade equal to or higher than 9.5 Values that results from a theoretical evaluation component (80%), and a practical evaluation component (2 assignments - 20%). The theoretical evaluation component that can be obtained by 2 tests (with weights of 25% and 30% each) +2 Quizzes (10% each) + 5% of evaluation done in TP classes, or by final exam(80%). Access to thefinal exam is conditioned to students with a record of attendance above 66.66% in theoretical classes. The 2nd test has a minimum score of 9.0 values. The theoretical evaluation component must be equal to or greater than 9.5 values.
