```A1.
Lectures:
The contents specified in section 5 of this guide are developed in
them, alternating the explanation of theoretical knowledge (CB2 and
CT2)with the
exposition of the general methods of posing problems (CB3 and CB5)
and the solving exercises-type (CEM9).
A2. Practices:
They consist of 5 sessions of two hours, where the student learn to
use new computation and experimental technologies for the content
of the subject (CB3, CB5, CEM9 y CT4) through practical activities
of computational simulation
(M6) and laboratory experiments (M9).
A3. Group tutorials:
They consist of sessions in seminar format (M15) or collective
sessions of resolution of doubts (M17) to deal with collateral
aspects necessary for the correct assimilation of the contents of
the subject.
```

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

5. ASSESSMENT METHODOLOGY

The evaluation is carried out mainly by means of a written exam, which consists mainly of exercises and practical problems. Both the choice of the resolution method and the accuracy and expression of the results will be evaluated in them. Additionally, it may contain questions of theory with a weight not exceeding 30% of the exam grade. This is rated from 0 to 10 points and with this it is intended to evaluate the competences CEM9, CT2, CT6, CB2, CB3, CB5 and the results Resul-01, Resul-02, Resul-03, Resul-04, Resul-05, Resul-06 and Resul-07. However, to pass the course, the minimum grade on the written exam must be greater than 4.5 points. The practices will evaluate the specific competences CEM9, CT2, CT4, CT6, CB2, CB3, CB4, CB5. Attendance and delivery of practical exercises are mandatory. In addition, it is necessary to obtain a minimum score of 3 points out of 10 in each of the reports of the practices presented. If the practice reports are not delivered on the dates set by the teacher through the PLATEA platform (deliveries by email are not accepted), the subject cannot be passed.

The course is approved or suspended in each call, in its entirety; including theory, problems and practices and the results Resul-01, Resul-02, Resul-03, Resul-04, Resul-05, Resul-06 and Resul-07.

The student may request a single test evaluation, in which the weight of the exam would be 100% of the grade of the subject, only under the exceptional circumstances set out in article 13 of the Reglamento de Régimen Académico y de Evaluación del Alumnado de la Universidad de Jaén . The application, accompanied by due justification, can only be made during the teaching period of the subject.

The minimum grade must be greater than 4.5 out of 10. 60% Practices and works Online Assistance and realization of reports. Both aspects are mandatory. It is necessary to obtain a minimum grade of 3 points out of 10 in each report. 35%

The application, accompanied by due justification, can only be made during the teaching period of the subject.

RESOURCES

For the adaptation of teaching and evaluation to the online mode, the tools enabled by the University of Jaén will be used for this purpose: Google Meet, Google Jamboard, Google Forms, ILIAS platform, etc.

In particular, for practices and the work, CAD and simulation software, as well as for numerical calculation will be used, which can be accessed through free-access computer rooms, virtual pcs or through free student licenses available for installation on their pcs.

In addition, for both exams and presentation of jobs or exercises in which it is applicable, it is necessary that the student has a webcam and microphone as means of interaction and identification against fraud.
