Methodologies
Methodologies
  Description
Introductory activities Introduction of the subject where the lecturer discusses the content to be worked on, the objectives to be evaluated, the methodology to be used, and the evaluation system.
Lecture The lecturer explains the theoretical content of each topic.
IT-based practicals in computer rooms Students are asked to do and deliver practicals, carried out with a computer, and related to the contents that are being worked on. These practicals are part of the continuous assessment of the subject.
Personal attention Students can receive personal attention in person or telematically during the hours of attention to students, and during practical hours in classroom.

Personalized attention
Description

Time that each lecturer has reserved to attend to and solve students' doubts.

Other comments and second exam session

Continuous assessment:

The practice grade will only be taken into account when it is higher than the average grade of the two partial tests. In this case, the weights of the practice grade and the two partial tests will be 20%, 40% and 40%, respectively. Otherwise, these weights will be 0%, 50% and 50%, respectively.

Second call:

The final grade will consist of 100% for the grade of an individual objective test on the content of the entire subject.
