The final exam is designed to check the acquisition of knowledge and skills by conducting a practical and an oral tests. The individual practical test in laboratory , lasting 5 hours, is the performance of a measurement on detector performances with the production of a written report. The oral test is designed to check, by means a conversation with the teacher, the ability to independently solve a problem concerning the program arguments. This analytical graduation has the aim to reliably assess the level of achievement of the expected learning outcomes.
