1. The part of theoretical concepts of the subject and exercises will
mean 75% of the total weight to be evaluated and is made up of two
tests, one in the middle of the semester:

- First partial: topics 1 to 6 (30% of the overall grade) - will be held
during class time
- Second part: topics 7 to 11 (45% of the overall mark) - will take
place in the ordinary exam date

To pass the subject as a whole, a passing of at least 40% of the Second
Part is required.

2. The practical part of the course consists of attending and carrying
out exercises before and during the laboratory sessions and in carrying
out a final practical exam.

The work and evaluation of the student in the laboratory (by means of
guided exercises, proposed, or tests) during the sessions counts for 5%
(non-recoverable), while the practical exam will be worth 20% (recoverable).

Attendance at all practical sessions is mandatory. Completion of all the
proposed exercises or tests will be mandatory to have the right to take
the practice exam. Therefore, it will be essential to have attended all
the sessions and to have done the work required in the sessions. In
these laboratory practices, the acquisition of the knowledge developed
in the theoretical classes will be demonstrated through the
implementation of designs proposed in the practice scripts.

A minimum grade of 4 out of 10 points in the total practicals will be
necessary to average with the theory and pass the subject. In case of
not reaching 4 points, the note of the sessions (5%) will be kept and
the extraordinary call will be attended

3. The extraordinary call will be made for those students who have
regularly followed the continuous assessment. Regarding theory, it will
consist of a single exam on all the theoretical contents of the subject,
which will account for 75% of the overall mark. As far as practices are
concerned, it will be an exam like the ordinary call that will be worth
20%. It will be necessary to do the theory exam when a minimum of 4 has
not been achieved in the second part and the practice exam when a
minimum of 4 has not been achieved in the practical exam. In addition,
students who do not reach 5 with the overall grade average for the
subject must take the theory exam, the practical exam or both (at the
discretion of each student) in order to reach 5 in the overall grade (in
the theory exam you will have to get at least a 5 to be able to pass the
subject and in the practicals a 4).
