Programa Práctico
Evaluación
Final grade is composed by the sum of two contributions:
1) Development along the course of 2 practical exercises (1 individual, 1 groups), which account for 50% of the final
grade
2) Written exam, which constitutes the remaining 50% ; it is compulsory to overcome this test to pass the course. The
test will consists of a single problem similar to those addressed during the course, developed along 2-3 hours; any
reference material is allowed.
