Grading rules (*)

(*) The evaluation calendar and grading rules will be approved before the start of the course.

The final grade is the weighted average of the one obtained in the periodic evaluation exercises (AV), the exercises carried out in the practical classes and directed activities (AD) and in the final work of the subject (AT). The periodic evaluation (A) is obtained as: AV = 0.4 * A1 + 0.6 * A2, being A1 and A2 the two periodic evaluations. The final grade for the subject will be: Subject grade = 0.7*(AV grade) + 0.4*(AD grade) + 0.1*(AT grade) if each of the AV, AD and AT grades has obtained a grade equal to or greater than 5.0. Otherwise, the mark of the subject will be: Subject grade = 0.8*(Nota AV) + 0.1*(Nota AD) + 0.1*(Nota AT) To pass , the mark of the course must be equal to or greater than 5.0. Criteria for qualification and admission to re-evaluation: Students suspended in the ordinary evaluation who have regularly taken the evaluation tests of the failed subject will have the option to take a re-evaluation test in the period established in the academic calendar. The students who have already passed it or the students qualified as not presented will not be able to present themselves to the re-evaluation test of a subject. The maximum grade in the case of taking the reevaluation exam will be five (5.0). The non-attendance of a student summoned to the re-evaluation test, held within the established period, may not give rise to another test with a later date Extraordinary evaluations will be carried out for those students who, due to proven force majeure, have not been able to carry out any of continuous assessment tests. These tests must be authorized by the corresponding head of studies, at the request of the professor responsible for the subject, and will be carried out within the corresponding academic period.

Test rules

If you perform any of the ongoing evaluation activities and laboratory in the scheduled period will be considered as zero score.   

Teaching methodology

The course consists of 4 hours a week of classes during the 15 weeks of the semester. The approximate distribution of the 60 contact hours is: 15 hours of lectures devoted to the exposition of the concepts and basic materials for the course. 15 hours of practical sessions devoted to the presentation of examples and exercises and problems. 24 hours laboratory and directed activities devoted to practical exercises to consolidate the objectives of general and specific learning of the subject. 6 hours devoted to the evaluation tests. Although most of the sessions will be given in the language indicated, sessions supported by other occasional guest experts may be held in other languages.

Office hours

Tuesday 12:00 am to 14:00 pm Module C1 Thursday 12:00 am to 14:00 pm Module C1 and hours to be agreed with professors.
