Type of Assessment
The final exam is designed to ensure the acquisition of knowledge and ability through the solution of some exercises.
The oral test consists of a technical conversation with the teacher to bring out the ability capacity to solve problems and to check the ability of the student to explain in clear and correct way the arguments of a assigned theorems.
