Assessment methods and criteria

verbal examination of 30 min as an average. 3 questions will be proposed to the candidate. Further questions will be proposed if there is a no-answer up to 5 questions. the evaluation will be given taking in account the comprehension and personal further study of the questions proposed, according to the following scheme: full comprehension and additional personal study of all the 3 questions: 30 com laude, excellent comprehension in all the 3 questions:28-30, good comprehension in all the 3 questions or excellent in 2 and reasonable/sufficient in 1: 27-26, reasonable in all the 3 questions or good in al least 2: 25-23, sufficient in all 3 or reasonable in at least 2: 22-18. For no answer there will be a penalty of 2-3 points
