Other comments and second call
The works and practices presented may be reviewed with an anti-plagiarism computer program that can carry out checks between the works of the students of the current and previous call and against external sources. In the case of plagiarism, the work will be classified as suspended. During the evaluation tests, the use of electronic resources (calculators, tablets, telephones, computers, etc.) will not be possible, except for those tests that, upon the express indication of the teacher, require the use of any of these resources. In the event of any irregularity during the examination or corresponding evaluation test, the exam will be withdrawn immediately, the student will be expelled and the grade will be suspended. In any case, it will comply with the provisions of the internal regulations of the ULe included in the document "Guidelines for action in cases of plagiarism, copying or fraud in exams or evaluation tests" (Approved Standing Committee of the Governing Council 29/01 / 2015).

The assessment of the practices will follow one of the following criteria (optionally both). The first will be an individual test that will consist of either a modification of the practice presented, or an exposition of it. The second will be the assessment of the own practice by the teacher. The first component will be a multiplying factor of the second.

In the second call, there will be an evaluation test of theoretical and practical content. Additionally, the delivery of one or more practices will be required for their subsequent evaluation in the same terms as in the first call (individual test and/or assessment of the practice).
