Extraordinary Examination will consist in an exam (theory and/or practice). Students who have not completed their laboratory classes, visits or field/site practical sessions, or sessions in computers classroom have to develop compensatory personal work.

Students following ‘no attendance’ system have to pass a final exam on theoretical and practical lessons explained in class, and practices carried out in laboratory and/or in computer classroom.

Exceptionally, some on-line evaluation methods could be included if health emergency reasons force to do it. In this case, the students will be informed about the changes.
