Type of Assessment
Final written and oral examination; no test in itinere. 6 ordinary exam sessions per year + 1 extraordinary exam session.
Written examination will last about 2-3 hours; the student willl be asked to solve 5-6 questions chosen from one or more problems about the dynamics of point particles and rigid bodies; the oral examination will be in front of a blackboard; the exam will last 30-40 minutes, on average. The student will be asked to discuss 2-3 specific topics; the student will be required to prove her/his knowledge of the different physical phenomena treated in the course, and should also be able to describe and reproduce proofs and calculations; she/he should also be able to make simple calculations.
The final marks will result according to the proven mastery of the discussed subjects and the ability to use a proper language.
