Class : learning outcomes will be verified through homeworks and test consisted of exercises of different degree of difficulty. A grade determined by the sum of points from these homeworks and test is a basis of assessment.

Laboratory: learning outcomes will be verified through  test consisted of exercises of different degree of difficulty. A grade determined by the sum of points from the test is a basis of assessment.
Lecture: final exam. A grade determined by the sum of points from that exam is a basis of assessment.
A grade from the course is consisted of the grade from laboratory (20%), the grade from classes (30%) and the grade from the final exam (50%). To take a final exam, students must receive a positive grade from classes. To attain a pass in the course students are required to pass the final exam.
