Development of the examination
LEARNING EVALUATION METHODS
The exam consists of 2 parts. In the first the student is asked to give written answers to 4 questions on the first 7 topics of the program, in the second to give written answers to 4 questions on the last 6 topics of the program. 1 hour and 30 minutes are given to the students to provide their answer for each part. The two tests can be sit by the students in two distinct sessions, but always within the same Academic Year. Further oral questions can be optionally made by the teacher to integrate the final examination grade.

LEARNING EVALUATION CRITERIA
For each tests, the students have to show a sufficient knowledge of the corresponding arguments, for at least 3 out of the 4 presented questions.

LEARNING MEASUREMENT CRITERIA
For each test, a score on the 18-30 scale is assigned. The minimum score required for each test is 18/30.

FINAL MARK ALLOCATION CRITERIA
The arithmetic average between the two scores is applied, with a rounding up strategy, and the result is proposed as final score for official registration.The maximum evaluation score is given when the student show a deep knowledge of the theoretical contents of the course and a remarkable ability in applying those concepts to practical problems.
