2 Introduction The exercises should be marked in accordance with the marking given in the key and guide for evaluation. In the guide, the marks that may be given for the major logical units are in the bordered parts. The parts without bordering contain the breakdown of the marks and reference to situations where the given mark can be awarded or can not be awarded. To ensure standardized evaluation, please do not divert from the marking in the guide. The marks can not be broken down further than indicated in the guide. If several solutions are given for the same problem, please evaluate the solution with the most given marks. In the case of several good solutions no extra marks can be awarded. The evaluation form, which only contains the marks for the major evaluation units, can be found at the end of the guide. One evaluation form should be filled for each examination paper and it should be attached to the examination paper (to the candidate s exercise sheet). The candidate receives this form at the seeing of the examination paper. The total marks awarded for the individual exercises, the mark awarded for the exam and the achieved percentage should also be indicated on the last page of the examination paper, in the tables provided. gyakorlati vizsga / október 16.
