-Attendance to classes is mandatory. In order for the student to be assessed with continuous assessment, the student must have attended 80% of the sessions of the course. Students who do not meet this criterion will be able to appear in the second call only, and will have to accredit the practical knowledge of the laboratory with an additional laboratory test. - It is not allowed the use of mobile systems for data communication during testing. - In order to obtain the final grade for the course, the notes of the different testsmust be greater than or equal to 4. - The various tests (1st and 2nd) may not bring any electronic device, only a scientific calculator (not programmable). The second round will be evaluated as follows: - It should be carried out again, and independently test development, test and final test types in the laboratory have a first call note 4 below. - To pass, all tests you must have a grade equal to or greater than 4 and grade of the subject is equal to or greater than 5 |
