Other comments and second exam session

In all the exams (1a i 2a call) only non-programmable scientific calculator can be used, no other electronic devices.

1st call:

- In order to succeed, all avaluative subjects must have a grade of 4 or higher and the global grade of the course must be equal or higher than 5.

2n call:

- Exams that have a grade under 4 in the 1st call will have to be repeated, and the global grade of the course must be equal or higher than 5.
