Methodology
Guided activities:
- Basis Theory: the lecturer will give the basic concepts in each chapter, in an ordered way, providing the needed written material and the indications for complementing the study with the bibliography and other resources (preferably virtual). The classroom classes will be devoted mainly to solve the doubts and to the orientation in the study of the most relevant aspects of the subject.
- Problem lectures: The problems lecturers will explain, and provide with the needed material, how to solve the typical problems of each part. Also, they will provide the necessary material and/or indications for completing the study with the bibliography and extra resources (preferably virtual). The classroom classes will be devoted mainly to solve doubts and to emphasize the key points in the problem-solving process.
- Laboratory work: several practices will be done during the course. They could be made at the faculty labs or directly at home with the minimum necessary presence in the labs. Some practices could be done virtually, using "virtual labs" to make the experiments.
Supervised activities:
- Personal (small group) work: during the students' attention time, the lecturers will be available to solve individual questions.
Autonomous activities:
- Preparation of lectures: students have to prepare the lectures, checking the virtual campus for the provided material.
- Preparation of practice work: students have to prepare the practice work, following the indications, and doing the tasks that will be given on the virtual campus.
- Solving problems: students have to solve the problems of the list given by the lecturers, independently of the problem classes done. The classroom classes will be used basically for solving the doubts that could have been emerged and to indicate the key points in the resolution.
- Study and preparation of exams: Personal work of the student to acquire the theoretical concepts as well as the ability to solve the problems.
- Preparation of the lab reports.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment
The final grade of the course will be obtained using the following proportions:
- 80% Grade of the two partial exams (40% each).
- 20% Grade of laboratory practice and practice exam (can include reports, lab work, written exam, ...).
- The problems and delivered activities will be used to improve the marks.
Only if the overall score obtained after the application of these percentages is equal to or higher than 5.0 (out of 10), the subject can be passed. However, in order to apply these percentages, the score (out of 10) of each of the partial exams must be equal to or higher than 3.5 and all the laboratory work must have been carried out. In the case that in one or both of the partial exams, the mark is lower than 3.5, the student will have to take the retaking exam of the part that has been failed with a mark lower than 3.5.
Laboratory reports and delivered problems cannot be retaken.
UAB Regulations: To be able to retake partial exams, the student must have previously been evaluated in a set of activities the weight of which is equivalent to a minimum of two-third parts of the total qualification of the subject.
Each partial exam will be retaken independently through a new exam. The mark of the retake exam will replace the mark of the corresponding partial exam.
Students who have been evaluated only 1/3 or less of the total subject will be considered "Not Evaluable".
UAB Regulations: In the event that the student realizes any irregularity that might lead to a significant variation in the qualification of some evaluation activity, he or she will qualify with 0 this evaluation activity, irrespective of the disciplinary process that could be started. If there are several irregularities in the evaluation of the same subject, the final qualification of this subject will be 0.
Any plagiarism (total or partial), copying or attemptedcopying, letting oneself be copied, etc., in any of the evaluable activities will be considered "irregularities leading to a significant variation in the qualification".
