Students with special educational needs should contact the Student Attention Service (Servicio de Atención y Ayudas al Estudiante) in order to receive the appropriate academic support

There are two types of evaluation modalities: overall evaluation or evaluation with one final exam.

The OVERALL EVALUATION modality consists of the following activities:

Attendance and Active participation: 10%. The level of attendance will be computed considering practical (reduced groups) and theoretical/problems sessions (lectures with theory groups). The level of active participation will be evaluated via the students participation and autonomous work in various proposed activities within lectures and lab sessions. The following competences will be evaluated with this method:  CB6, CB7, CB8, CB9, CB10, CG1, CG2, CG3, CG4, CG5, CG7, CG9, CT1, CT2, CT3, CT4, CT6. A positive evaluation assesed with this method will mean that the students have achieved  following competencies or learning results:  34, 40, 41.

 

Theoretical concepts: 30%. At the end of the semester (final exam date proposed by the center), there is a written exam about theoretical questions developed during lectures. In addition, the continuous evaluation related to the questions proposed as autonomous work or through ILIAS (LMS). The following competences will be evaluated with this method: CB9, CB10, CG2, CG3, CG4, CT1, CT2, CE4, CE6, CE7, CE8, CE9. A positive evaluation assesed with this method will mean that the students have achieved  following competencies or learning results:  27, 28, 31, 33, 34, 40, 41, 43.

Exercises and case studies: 30%. At the end of the semester, there is a written final exam with the problems and practical cases studied in lectures. In addition, the development and presentation of the material related to activities proposed through the LMS is also evaluated (continuous evaluation). The following competences will be evaluated with this method: CB6, CB7, CB8, CB9, CB10, CG2, CG3, CG4, CG5, CG7, CG9, CT1, CT2, CT3, CT4, CT6, CT7, CE4, CE6, CE7, CE8, CE9. A positive evaluation assesed with this method will mean that the students have achieved  following competencies or learning results:  27, 28, 31, 33, 34, 40, 41, 43.

Lab/computer practical sessions: 30%. This item takes into account the development of the design practices and the documentation requested. The following competences will be evaluated with this method: CB6, CB7, CB8, CB9, CB10, CG2, CG3, CG4, CG5, CG7, CG9, CT1, CT2, CT3, CT4, CT6, CT7, CE4, CE6, CE7, CE8, CE9. A positive evaluation assesed with this method will mean that the students have achieved  following competencies or learning results:  27, 28, 31, 33, 34, 40, 41, 43.

 

The grade system is ruled by RD 1125/2003 of 5th September, which established the European Credits System for the official university studies.

 

There is a final written exam that will take place in the corresponding dates established by the center. This exam evaluates lecture part (S2 and S3) of the subject and the student should probe to have acquired its competences and skills. The weight of this exam on the final mark is 50 % of S2 and S3.

 

In order to pass the course, a mark equal or higher than 4 out of 10 must be obtained in both the lectures and practical sessions. Moreover, to pass the course the student should obtain an overall mark higher than 5.0, taking into account the previous conditions.

The marks obtained through the continuous evaluation will be kept until the end of the course.

 

The FINAL EXAM modality is ruled by the following conditions:

There is a final exam with the following weights: 70% lectures (theoretical sessions- S1 and problems-S2) and 30% for the practical/computer sessions (S4).

In order to pass the course, a mark equal or higher than 5 out of 10 must be obtained in both the lectures and practical sessions. Moreover, to pass the course the student should obtain an overall mark higher than 5.0 taking into account the previous conditions.

Those students that obtain a mark equal or higher than 5 out of 10 in practical sessions do not have to do the practical exam.

The marks obtained in the parts passed will be kept until the end of the academic year.
