* Teachers can stablish the compulsory or optional presentation of a dossier - exercise related to each of the seminars. This work can be evaluated in the manner determined by the teacher (assigning a grade, using this grade to refine / recalculate the final grade or other uses at teacher’s self criteria.

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

Continuous assessment activities

Title Weight Hours ECTS Learning outcomes
1st Exam (Themes 1-3 + seminars) 40% of total EC grade 3 0.12 KM02, KM03, KM04, SM01
Final Exam The same as each previous exams 2 0.08 CM01, KM01, KM02, KM03, KM04, SM01
Assignements on Seminars 20% of total EC grade 0 0 CM01, KM01, KM02, KM03, KM04, SM01
2n Exam (Themes 4 - 8) 40% of total EC grade 3 0.12 CM01, KM01, KM02

-CONTINOUS ASSESMENT (CA):


  • Two midterm examinations (theory and seminars), graded out of 10.

First midterm: theory + seminars = 40% of the final grade.

Second midterm: theory + seminars = 40% of the final grade.

Students who sit either midterm are not eligible for a "Not Assessed" grade, since each midterm accounts for more than 35% of the continuous assessment.


  • Assignments, reports, and exercises account for 20% of the final grade.

Submission may be mandatory or optional depending on the instructor.

Failure to submit three mandatory assignments by the deadline results in the loss of this component (20%).

Assignments are not recoverable after the deadline.


CA Grade = (First Midterm × 0.4) + (Second Midterm × 0.4) + (Assignments × 0.2)


To pass:

  • CA grade ≥ 5.0.
  • Each midterm grade must be > 3.0.

If either midterm grade is ≤ 3.0, the CA grade cannot be calculated and the student must take the corresponding recovery examination.


Final Recovery Examination

The Recovery exam consists of:

  1. Recovery of the first midterm.
  2. Recovery of the second midterm.

Assignments and seminar reports cannot be retaken.


If the recovery mark is lower than the original midterm mark, the arithmetic mean of the two marks will be used.

If either component remains below 3.0 after the recovery, the final result will be Fail.


Final Grade = (First Midterm × 0.4) + (Second Midterm × 0.4) + (Assignments × 0.2)


Special case: If,

  • Final grade ≥ 4.8;
  • Mandatory assignments have been submitted correctly (no more than two missing);
  • Assignment grade ≥ 5;

the final mark may be increased to 5.0, allowing the student to pass the course.


-SINGLE ASSESMENT:


  • Final comprehensive examination covering all theoretical and seminar content.
  • All required seminar assignments/reports must be submitted along with the exam.

Calculation of final grade:

  • Final Grade = (Exam × 0.8) + (Assignments × 0.2). A minimum grade of 5.0 is required to pass.

Single-Assessment Recovery

  • A new comprehensive final exam covering all course content will be administered.
  • Assignments on seminars are not recoverable; the grade previously obtained for this component will be retained.

Calculation of the recovery grade:

Final Grade=(Recovery Exam Grade × 0.8)+(Assignments × 0.2).A minimum grade of 5.0 is required to pass.


OTHER CONSIDERATIONS:


  1. any type of academic irregularity (copying, misuse of AI, etc.) results in a grade of 0 in the affected activity.
  2. In the event that several irregularities are verified in the evaluation acts of the same subject, the final grade of the subject will be 0.
  3. Activities with irregularities will not be recoverable.


-Use of Artificial Intelligence:


It is only allowed for:

  1. Bibliographic or information search tasks
  2. Proofreading
  3. Translations
  4. Other uses explicitly authorized by the teacher.

In addition, the student must:

  1. Identify the parts that have been generated with AI.
  2. Specify the tools used.
  3. Include a critical reflection on how these have influenced the process and the final result of the activity.


Lack of transparency in the use of AI in any evaluable activity will be considered a lack of academic honesty and will result in the activity being rated with 0 and not being able to be recovered.
