The teacher, in contact with his students, may take under consideration special situations related to students' participation in class. In general, it is necessary to achieve at least 4.0 points in the written test. Students who do not make the objective test, and who do not reach at least 50 percent in the rest of the assessment tests will be qualified with a NON PRESENTADO (NP). Those who do not pass at the first opportunity, will go to the second. In July, in addition to the exam, students will be asked to hand in an extra work. Students with exemption or part-time status should talk to the teacher to establish a program of additional work to replace regular classes and exams.
