Lecture or master classes (big groups): Introductory activities, Master classes about theoretical contents or case studies resolutions.

Lab Sessions: Active participation developing supervised practices about applications configuration, traffic measurements and real time multimedia applications programming.

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.

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).

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).

Lab/computer practical sessions: 30%. This item takes into account the development of the design practices and the documentation requested.

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.
