Type of Assessment - Last names A-L
Students can take part in 3 intermediate tests during the course. After passing the intermediate tests, the oral test (a single question) and the final vote are directly accessible. If you do not take part or pass the intermediate tests, you must pass a written test (very similar to one of the intermediate tests) and the oral test.
The tests are oriented to verify Ca4 skills in close relation to the cc4 objectives. In particular, the written tests assess the ability to select and use suitable mathematical models for the description and performance estimation of thermodynamic cycles and corresponding energy systems, while the oral question is dedicated to the evaluation of the ability to describe energy systems and their components, highlighting their peculiarities and performance characteristics The student must be able to show at least sufficient knowledge of mathematical/physical modelling methods of energy systems of general interest (written test ) and sufficient knowledge of the energy components and systems described in the course (oral test).
