Assessment comments

The mixed test and the problem-solving tests constitute 80% of the
grade. The evaluation of laboratory practices and through ICT constitute
the remaining 20%.

Description of the evaluation and distribution of points.

FIRST OPPORTUNITY

A) MIXED TEST:

   
It will consist of two midterm exams of 6 points (maximum) each. In
order to pass the subject, a minimum of 3 points must be obtained in
each one. Once obtained, the grade of the mixed exam will be the average
of the grades of both midterm exams.

    If any of the midterm
exams are not passed, the student will have the opportunity to pass them
in the final exam (1st opportunity).

B) PROBLEM SOLVING:

    It will consist of a set of tests with a maximum combined evaluation of 2 points, with a minimum of 1 to pass the course.

   
In case of not passing the tests, the student will have a problem
solving exam on the same date and time as the final exam (see item A).
This exam must be passed in order to pass the course.

C) LABORATORY/TIC PRACTICES:

   
It will consist of a set of laboratory and computer simulation tasks
(ICT) with a maximum joint evaluation of 2 points, with a minimum of 1
to pass the course. At the beginning of each practice, the student must
pass a previous test. If the student fails the test, the grade of the
corresponding practice will be halved.

    In case of not passing
the assignments, the student will have a laboratory exam on the same
date and time as the final exam (see item A). This exam must be passed
in order to pass the course.  

FINAL GRADE: if the three parts
(A, B and C) are passed, the final grade will be the sum of them. In
case of failing, such a sum will be halved.

Additional work (optional): the
student who has passed the course will have the option of voluntarily
submitting a written work whose content and length (no more than 20
DINA4 pages, single spaced, New Roman font size 10 or similar, with
margins of 2 cm on each side of the page) will be determined by the
theory professor. The score for this work (1 point maximum) will be
added to the FINAL grade indicated above (to be reduced if the maximum
of 10 points is exceeded).

Detection of plagiarism or copying of work: the
fraudulent performance of the tests or evaluation activities will
directly imply the qualification of failure '0' in the corresponding
opportunity of the subject, thus invalidating any qualification obtained
in all the evaluation activities for the second and advanced calls.

SECOND OPPORTUNITY

For
the second opportunity the student may take a mixed test similar in
content and difficulty to that of the first opportunity, and must pass
both parts. The grade obtained in the mixed test will be added to the
laboratory practices, ICT and problem solving grades obtained in the
first opportunity. In case of not passing the problem solving or the
practicals, the student will have the corresponding exams, within the
timetable corresponding to the mixed test. For the calculation of the
total grade, the same criteria will be followed as for the first
opportunity.

Students enrolled part-time or who have been granted
academic dispensation of exemption from attendance, as established by
the Rule that regulates the regime of dedication to the study of
undergraduate students at UDC (Arts. 2.3; 3.b; 4.3 and 7.5)
(04/05/2017), will take the same evaluation tests as students enrolled
full-time. He/she will have the option of taking a lab/ICT practicum
exam at each opportunity.

The evaluation criteria contemplated in
Table A-II/1 of the STCW Code, and collected in the Quality Assurance
System, will be taken into account when designing and carrying out the
evaluation.
