According to art. 6 of the UCLM Student Evaluation Regulations, it must be provided to students who cannot regularly attend face-to-face training activities the passing of the subject, having the right (art. 13.2) to be globally graded, in 2 annual calls per subject , an ordinary and an extraordinary one (evaluating 100% of the competences).

Evaluation criteria for the final exam:
  • Continuous assessment:
    LABS
    To be eligible to take the final lab exam, the student must previously complete all lab sessions. For each lab, the student must complete and upload all the pre-lab assignments into the course website before the deadline specified for each lab session. Failure to do so will result in the ineligibility to participate in the corresponding lab session. If for a justified reason, a student misses participating in one or two lab sessions, he/she will be able to attend a retake lab session scheduled by the end of the semester. A maximum of two lab sessions may be recovered.
    The final lab exam will take place at the scheduled final exam date. The final lab exam will count for 20% of the total final mark. The student must get at least 4/10 in the lab exam to be eligible to pass the course.

    THEORY
    One mid-term exam will be scheduled during the term, Exam 1. The exam will consist of two parts: test and problems. A minimum mark of 40% must be obtained in each part to pass the exam. Students passing the mid-term exam (Exam 1) will be exempted from taking it once again.
    During the final exam session, all students have to take Exam 2 based on the material covered in the second part of the course. Exam 2 will consist of two parts: a test and problems. A minimum mark of 40% must be obtained in each part of the Exam 2. An overall mark of 4/10 to pass Exam 2. Exam 1 and Exam 2 will count for 50% of the final course mark.

    IMPORTANT: To pass the course, an overall average of 5/10 is required and the following conditions should be met. A mark of at least 4/10 in the lab exams, Exam 1 and Exam 2 and participation in all lab sessions. A mark of 40% or higher in the tests and problems of Exam 1 and Exam 2. The student who fails to meet all these requirements will automatically get a failure mark no greater than 4.0, even if he/she has obtained an average mark of 5/10 or higher.
  • Non-continuous evaluation:
    LABS
    The student will have to take a final lab exam using the Packet Tracer tool, counting for 20% of the final mark. The student must get at least 4/10 in the lab exam to be eligible to pass the course.

    The student who has NOT participated in all lab sessions will also have to take a practical exam done at the lab. The student will have to show that he/she is familiar with the lab equipment, characteristics, and configuration procedures. Only those students having successfully passed the final Lab Exam, Exam 1, and Exam 2 (see below) will be eligible to take the practical exam. This practical lab exam will count for 12,5% of the final mark. Failure to pass this exam will result in a final mark no higher than 4 (failed).

    THEORY
    The student will have to take an exam consisting of two parts: test and problems. To pass the exam, the student must get a minimum mark of 40% in each one of the parts. The exam will count for 67,5% of the final mark.

    IMPORTANT: To pass the course, the students must obtain a mark of 4 or higher in the lab exam and in the final exam with a mark of at least 40% in each of the parts of the latter: test and problems. The student who fails to get an overall mark of at least 5/10 will automatically get a failure mark no greater than 4.0, even if he/she has obtained an average mark of 5.0 or higher.

Specifications for the resit/retake exam:
CONTINUOUS ASSESSMENT
The same criteria as for the final exam will apply. The students registered under the continuous evaluation modality will only have to take those exams whose pass conditions are not met. The marks of all the activities evaluated throughout the term and the marks of those exams whose marks are equal or greater than 5 will be taken into account. Failing to meet all conditions will result in a final mark no greater than 4/10 (failure), even if the overall average is 5/10 or higher.

NON-CONTINUOUS ASSESSMENT
The same criteria as for the final exam will apply.
The student who has NOT participated in all lab sessions will have to take a practical exam, done at the lab. The student will have to show that he/she is familiar with the lab equipment, characteristics, and configuration procedures. Only those students having successfully passed all the exams will be eligible to take the practical exam.
The marks of all the activities evaluated throughout the term and the marks of the final theory and lab exams will be considered only if their marks are equal or greater than 5. These marks together with the ones obtained in the retake exam will be used to compute the final mark. In the case that the mark of any of the retake exam is lower than 4/10 and/or if the marks of any of its parts are lower than 40% will result on a final course mark no greater than 4/10 (failure), even if the overall average is 5/10 or higher.
The marks of those students obtaining a mark of 5 or higher in the lab exam and having participated in all lab sessions will be kept and validated only for one course.
Specifications for the second resit / retake exam:
ASSESSMENT CRITERIA THE SPECIAL EXAM SESSION FOR COMPLETION OF STUDIES

There will be a written exam. This examination will consist of a theory part (70%), and a lab part (30%). To pass the course, the student must get at least 5/10 in each one of the two parts: theory and lab. Those students having missed one or more lab sessions will have to pass a final test in the lab in order to show that he/she has acquired the required skills to configure and operate real-world network devices.
