Teaching methods

  • MD01. Theoretical classes

Assessment methods (Instruments, criteria and percentages)

Ordinary assessment session

The student assessment and final score will take into account the presentation of seminars, the work in problem solving and practical sessions and the final exam, in which the students have to show the skills acquired during the course.

  • Exam: 50%
  • Practical sessions, problems and participation in class: 50%

Extraordinary assessment session

The extraordinary assessment test will be the same as the single final assessment test.

Single final assessment

The students that, according to the rules of the UGR and within the fixed time frame, choose to have a single final assessment test, will make a theoretical (50%) and a practical/problems exam (50%) which will allow a complete assessment of their knowledge.
