### Teaching method

Teaching Method is based on conferences and problems solving sessions with the support of a personal attending schedule.

### Evaluation method

Frequency

Frequency will be granted to any student who does not unjustifiably miss more than 1/3 of the practical classes taught. Students who have obtained it in one of the semesters of the 2018/2019 school year or who have any of the special statutes provided by law are exempt from attendance.

The evaluation is carried out through Continuous evaluation or Exam evaluation.

Continuous evaluation

During the semester two tests will be carried out with a duration of 1 hour 30 minutes. Each test is rated up to a maximum of 20 values.

1st Test (t1): all students enrolled in the course may present themselves to the 1st test.

2nd Test (t2): all the students enrolled in the course that have obtained a frequency or have a special status may submit to the 2nd test.

The classification of continuous evaluation (CA) is obtained by the following formula:

AC =(t1 + t2) / 2

The student is approved in the course if AC is greater than or equal to 9.5 values. If AC is less than 16.5, the final grade of the course will be AC. If AC is greater than or equal to 16.5 values, the student can choose between obtaining a final grade of 16 values or performing a supplementary examination.

Exam

All the students enrolled in the course that have obtained Frequency or have special status may submit to the Exam.

At the date and time scheduled for the Exam in January 2020, any student enrolled in the course that has obtained Frequency or has special status and who has not obtained approval in the Continuous Evaluation can take the exam for 3 hours or can opt to repeat one of the1 hour 30 minutes . If the student chooses to repeat one of the tests, the classification is calculated as in the case of Continuous Evaluation.

If the student performs the Exam and his or her classification is greater than or equal to 9.5, the student is approved with the grade obtained if it is less than 16.5. If the grade is greater than or equal to 16.5 values, the student can choose between obtaining a final grade of 16 values or performing a supplementary examination.

Grade improvement

Students have the right to improve grade by enrollment within the established deadlines, at the time of the Exam. In this case, they may take the 3-hour Exam or repeat one of the 1-hour 30-minute tests as described in the previous paragraph. In the case that a student wants to improve his grade, having obtained approval in a previous semester, he can only take the 3-hour Exam.

Logistics

Only those students who carry an official identification document with a photograph (for example, Citizen''s Card, Identity Card, Passport, some versions of Student Cards) and a blank examination notebook may take any of the tests.

Final considerations

In all that this Regulation is missing, the FCT-UNL General Regulations are valid.
