The teaching method relies on weekly theoretical lectures and practical classes, supported by an attending schedule. Practical examples are provided in the theoretical lectures. Exercises are solved under teacher supervision in the practical classes.
The continuous evaluation method consists in two tests. The student is approved if the average of the two grades is upper or equal to 9.5.
Note: The student may optionally improve the grade of the first test at the date of the second test.
The non-approved student in continuous evaluation must attend the final exam, being aproved if the grade is upper or equal to 9.5.
