Calculation formula of final grade
The assessment of knowledge will be done through a mandatory final exam and by the student's performance in the practical classes. The final grade will be calculated by: 0.75 x exam mark + 0.25 x mark practice
The student can dismiss the final exam by performing two tests (T1, T2) throughout the semester, provided that the final grade calculated (according to 1) from the arithmetic mean of both tests and the practical note, is positive. Performing these tests is optional.
The final exam of the normal period will consist of two modules corresponding to the subject of the tests referred to in point 2. Students who have carried out the tests provided for in point 2 may choose to carry out the modules that best fit the final exam of the normal period, Sense of improving classification. The final grade of this exam will be obtained through the arithmetic mean of the classifications obtained in the two modules. In the case of students who have opted to take the test and then repeat the module under examination, the note considered will be the more favorable of the two.
The final exam of the period of recourse and special time will involve all the subjects taught. The final classification will be obtained from the note obtained by the student in this exam and the practical note.
