This is an optional experimental subject that requires in situ attendance of the students at the lab. Attendance to each of the four in situ sessions is compulsory. The classes' schedule is published before the enrolment period. Make sure that you will be able to attend the four sessions at UVigo before you enrol in this subject. If you are working, make sure that you get a commitment in writing from your employers allowing you to attend the four scheduled sessions at UVigo before you enrol. Otherwise, DO NOT ENROL, choose another optional subject that does not require in situ attendance. Job commitments are not a recognised cause for leave of absence. Porto students please note: UPorto's general 25% leave of absence DOES NOT APPLY at Uvigo. The only recognised causes for leave of absence at UVigo are the usual force majeure causes: death, serious illness, law enforcement, and acts of God, and they must be officially sanctioned by UVigo's administrative services by means of suitable documentary proof. If a leave of absence is officially sanctioned by UVigo, the evaluation of the missed session will be arranged on a case-per-case basis with consideration of the particular circumstances of the case.
