Assessment methods (Instruments, criteria and percentages)

Ordinary assessment session

Assessment in the ordinary session will take place via two written tests, with problems and questions of the relevant material that's been reviewed up to that date. The final marks in the continuous evaluation system of the ordinary session will have the following weights:

  • First written test: 35-40%
  • Second written test (same date as the ordinary exam session): 40-45%
  • In order to pass the subject via continuous evaluation, a minimum score of 3 points over 10 must be obtained in both written tests. If a student is below that threshold in the first written test, they will automatically have to concur to the extraordinary assessment session
  • Lab sessions: 20%. In these, the competency will be assessed by a practical test and/or through the lab reports. In order to pass the whole subject, it is mandatory to pass the lab sessions (5 or more points over 10), successfully complete all the sessions and submit all the corresponding reports

Students will pass the subject by continuous evaluation when their final mark exceeds 5 points (out of 10) according to this weighting scheme.

Extraordinary assessment session

In the extraordinary session there will be a single final exam representing 80% of the final mark and an additional exam covering the concepts of the lab sessions, weighting 20%. This lab exam will take place on the same date but at a different time than the written exam of the extraordinary session.

Single final assessment

Students who, in accordance with the UGR guidelines, terms and deadlines, opt for this form of evaluation, will take an exam covering the theoretical part of the subject. Another exam will be required in order to assess the practical part. The aforementioned weights will be applied to this evaluation, being again compulsory to pass the lab exam in order to pass the whole subject.

Additional information

  • Use of mobile phones is not allowed during lectures and lab sessions
  • Following the advice from the CRUE and the diversity and inclusion office of the UGR, the assessment and learning evaluation will be designed following the principle of accessibility for everyone, making the necessary adaptations that enable the learning process and the demonstration of knowledge regardless of special needs and limitations of individuals
