Except in exceptional circumstances class attendance on continuous assessment is mandatory. Continuous assessment is used to evaluate the course and it is based on the student's work in the laboratory and the supervised work on the contents of the subject. In May there is a final exam on the official date to those students who have not passed the continuous assessment and want to pass the course. The final exam will be graded between 0 and 10 points and it Includes all course topics. To pass this final exam students must obtain at least five points. Students who wish to improve their continuous assessment grade may attend to final exam. In this case the grade obtained in this final exam will be the final grade of the course. Students who have passed the continuous assessment and are satisfied with your grade does not need to attend at this final exam. Throughout the four-month period the students will receive information about their progress in the continuous assessment. The final grade of the continuous assessment will be communicated to students in the last class, always before the final exam. Delivery of the supervised work will be the last week of class and will mean the official participation in the continuous assessment. The latter means have been presented to the subject although the student has not made the final exam.

The additional assessment in July will consist of a final exam for those students who have not passed neither the continuous assessment nor the final exam in May. In both cases the final grade for the course will be the grade of this final exam. This final exam will be graded from 0 to 10 points, and it includes all the topics of the subject. To pass the course students must obtain at least five points.

Note that there is no two calls but this one is unique, although there are two final exams.
