Evaluation method
A minimal final grade of 45.0% is mandatory in this course. This final grade is the result of a theoric evaluation (60%) , 10 % from 5 quizzes and pratical evaluation (30%),The theoric evaluation may be obtained from the weighted average of the classifications obtained in three tests ( 10%, 17% and 33% ) or in the second final exam. Students are required to have a minimum of 66% of class attendance to be admitted to the final exam. A minimal classification of 40% is manadatory for the 3rd test A minimal final theoric grade of 45% is mandatory. In this case, theoric evaluation may only be attained in the second final exam.
