The evaluation will have two parts: theoretical module (80% of the course), practical module (20%) The theoretical module will be assessed through a single examination consisting of multiple choice questions. The practical module will be evaluated on a continuing basis in each practice by assessing the lab notebook. Attendance at practical module is obligatory. Failure to attend all of the practices will be a practical examination. In any case, the evaluation of the thoretical module must have a grade equal to or greater than 4,5 for the average final. This is valid for the first call in January. From this call, the final grade will be 100% the mark of the theoretical module and a grade equal to or greater than 5 will be necessary to pass. Once the practices are approved it will not be necessary to repeat them. The examination of the December call will consist of 4 questions.
