Other comments and second exam session |
- 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 project only can be presented by student with grade >7 at the first test. - 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 |
