Modalità di esame: Prova scritta (in aula); Prova orale facoltativa; Elaborato scritto prodotto in gruppo;

Exam: Written test; Optional oral exam; Group essay;

... The final assessment is based on a written test and a optional oral examination. The written test includes numerical exercises related to the most important topics. The time slot for the written examination is 2 hours. The final score is given by a weighted average of the evaluations for the written examinations plus the evaluation of the laboratory reports. Max score obtained with written examination: 28/30 Additional points from laboratory report: from +0 to +4 Oral exam (colloquim of 15-20 minutes) is not mandatory and can be requeted by the stundent: points from -3 to maximum +3
