Modalità di esame: Prova scritta (in aula);
Exam: Written test;
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
Exam: Written test;
The exam is in written form only and consists at least of: - multiple choice sentences/questions - fast numerical exercises on electrified traction systems sizing Duration: 3 hours. Each multiple-choice question has just one correct answer. The numerical exercises require to solve a numerical problem similar to those shown during the practice lectures. During the exam it is possible to use just a simple scientific calculator (or the calculator available in Respondus interface), a pen and white papers. Exchange information among students is not permitted by any means. Use of multimedia devices such as cell phone, tablet, pc, smart watch is not allowed. Use of any written material such as notes, textbooks or equivalent materials is not allowed.
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
