Guest lecture / keynote speech |

In some lectures, questions will be asked (orally and/or in writing) to the students on aspects dealt with in the session, which they will have to answer on the spot in order to assess the individual performance of the session. |

Attendance is mandatory. Each day of unexcused absence will mean 0.5 points less in the final grade. |

First chance: Presenting a bibliographic review paper at the last seminar session.
Second chance: Students who have not presented a paper at the first opportunity may submit their paper in WRITING on the date of the second opportunity test (detailed guidelines for submitting a paper are available in Moodle). SECOND CHANCE PAPERS MAY GET A MAXIMUM GRADE OF 5 (passed). |

Assessment comments |
In order to pass the course it is REQUIRED to pass the theory exam with a grade of at least 4. Otherwise, the course will be suspended regardless of the remaining grades and the lowest numerical grade will be placed (i) the average grade with the above percentages or (ii) the grade of the theory exam). Failure to attend the theory exam will result in no final grade ("No presentado"). Students with dispensation from attendance: it will be possible to take the tests using teledocency tools. Cheating in the assessment tests or in any assessment activity will directly imply the qualification of failing '0' in the subject, thus invalidating any qualification obtained in all the assessment activities for the extraordinary exam session.

La bibliografía básica es suficiente para una asignatura de licenciatura. Además, el alumno debe buscar trabajos científicos para realizar el trabajo tutelado; los trabajos concretos varían para cada alumno. |

Other comments |
Students are encouraged to use the tutorials to resolve questions with the teacher. Green Campus Programme Faculty of Science: to contribute to achieving an immediate sustainable environment and to comply with point 6 of the "Environmental Declaration of the Faculty of Science (2020)", the written assignments will be mainly requested in electronic format. |
