Students who intend to attend the UC under continuous assessment are required to carry out all assessments of the two components:

- Theoretical-practical component (Tp) is evaluated by tests. The Tp component grade is given by the average of the tests.

- Laboratory Component (L) with mandatory completion of laboratory work. The evaluation of the laboratories is composed of the performance in class and of the reports and other documents presented of the different laboratory works.

2- Assessment regime by exams with mandatory laboratory work

Students who choose the assessment system by exams will take a written test in which all the subjects corresponding to the Tp component will be evaluated. Examination tests are carried out at scheduled times at School level.

The minimum grade for the average of the Tests, the Laboratory Component and the Exam is 9.5 (nine point five points) .

3-Evaluation regime at the time of exams

The exam consists of two parts, one for the first part, and one for the second part. Students who did not pass the continuous assessment system and are obliged to take an exam for their approval, may decide not to take one of the parts of that exam and, in that part, they will be awarded the classification obtained in the corresponding test. The classifications obtained in the parts carried out in the exam replace those eventually obtained in tests for the calculation of the average Tp.

NF = 65% Tp + 35% L;

The final grade (NF) in the assessment system by exams will be the weighted average of the classification obtained at the time of the exam (NE) and that obtained in the mandatory Laboratory component (L) or equivalent,

NF = 65% NE + 35% L ;

Students who have obtained NF ≥9.5 values will be approved with the final classification (NF) determined by rounding up to units.

By the end of the second week of classes, students covered by special statutes (student worker, association manager, high-level athletes, etc.) must inform the UC responsible for their specific situation and respective implications for the evaluations.
