Eligibility for exams
Five to eight short tests, around 15 minutes each, will be given in the classes along the course. These tests will be announced in each previous theoretical class. After each chapter the students must do an exercise proposed. To have frequency, the students must do, at least, three short tests and all homework.
Calculation formula of final grade
70% for the mark in the final examination. 20% for the marks in the short tests (4 in a total of 5 will be taken on account). 10% for the homework (the number of homework done and the mark in one of this homework will be taken into consideration).
Special assessment (TE, DA, ...)
Examinations, accordingly to the calendar draw by MIEQ
