Qualification system The final score is the sum of the following partial grades: Nfinal = 0.7 Npf Nelt Nfinal: final grade. Npf: final test score. Nelt: scores of teaching and laboratory work. The final test consists of a part with issues related to the learning objectives of the course in terms of knowledge or understanding concepts, and a set of application exercises. The rating of teaching and laboratory work will consist of technical reports delivery practices and / or jobs. A final test will be conducted reassessment students who meet the requirements established by the regulations of the center, which will consist of a single test in which all of the matter that will be assessed during the course. Regulations for carrying out activities If you have not done laboratory activities, work or evaluation, is considered not scored. It is considered not submitted when not perform any tests. 6 / 7
