Grading and evaluating student work in class and at the final exam

During semester two exams will be performed. Final examinations will be administered during formal examination periods. The following percentage equivalents apply to final grade: <55% Failure; 56%-66% (2); 67%-78% (3); 79%-90% (4);> 90% (5). Lecturers do not give grades. Students earn grades.
