C1 CMECES1 That students have demonstrated possession and understanding of knowledge in an area of study that is based on general secondary education, and is usually found at a level that, although supported by advanced textbooks, also includes some aspects that involve knowledge from the cutting edge of their field of study
C2 CMECES2 That students know how to apply their knowledge to their work or vocation in a professional manner and possess the skills that are usually demonstrated through the development and defense of arguments and the resolution of problems within their area of study.
C3 CMECES3 That students have the ability to gather and interpret relevant data (normally within their area of study) to make judgments that include reflection on relevant issues of a social, scientific or ethical nature.
C4 CMECES4 That students can transmit information, ideas, problems and solutions to both a specialised and non-specialised audience
C5 CMECES5 That students have developed those learning skills necessary to undertake further studies with a high degree of autonomy

Description
At the beginning of the course, tutoring sessions will be scheduled and specific forums will be set up for questions. Throughout the course tutoring sessions will be adapted depending on the learning outcomes and the specific circumstances of each situation.

Assessment
  Description Qualification
Problem solving, classroom exercises Resolution of proposed problems. Continuous evaluation. 15
Laboratory practicals Compulsory and exclusive. Continuous evaluation. 15
Mixed tests Final, individual, on-site exam on exercises and/or theoretical developments. 50
Practical tests Final, individual, on-site exam on practical problem solving 20
 
Other comments and second call

To qualify for the continuous evaluation it will be necessary to complete more than 50% of the activities and practices. In order to obtain averages it will be necessary to obtain a minimum of 4 points out of 10 in the sections of tests and continuous evaluation.

The percentages of qualification exposed are orientative. The professors can consider punctual and/or exceptional situations that justify a redistribution of the previous percentages, communicating it previously to the students.

In the second call only theoretical (75%) and practical (25%) tests will be carried out and considered. For the realization of the mixed tests it is only allowed the use of writing material, correctors, rulers, compasses... and scientific calculator with a screen no larger than 3 lines.

Failure to comply with these rules will result in the immediate withdrawal of the exam, expulsion from the exam and a failing grade. When taking the practical tests, students may bring any personal material they deem appropriate.
