    Teaching methodology

    There are two types of classes: theory and laboratory classes.

    During the first weeks there will be no laboratory classes.

    The theory classes will be expository by the teacher, including theoretical concepts, practical examples and resolution of training exercises.

    The laboratory classes will be of two types: the first classes will be directed, aimed at knowing the tools and programming languages used; The following classes will be oriented to the realization of a small project.

    In addition, depending on the availability of each course, there will be conferences by experts.

    Evaluation methodology

    50% Take-home exam
    50% Laboratory

    The take-home exam will be held at the end of the course. The statement will be delivered in class and will be returned resolved after about 10 days. It is an individual test that must be done by hand on the exam sheets distributed by the teacher.

    The laboratory grade is obtained from the follow-up notes of the practice sessions prepared by each teacher and the evaluation of the project. To evaluate the project, students must submit a written report.
