Distributed assessment – consists on the execution of two mid-term tests. On the date of the final exam it is possible to repeat one mid-term test upon invitation from the structors. The theoretical grade is calculated using the following formula: theor_grade = 35% 1st test + 35% 2nd test Centralized assessment – consists on the execution of a final exam. In this case the theoretical grade is the grade of the exam. Students that opted by the distributed assessment can change to the centralized assessment any time during the semester.
