Teaching methods
Theoretical lessons will be completed with practical ones consisting into
the assisted solution of exercises on the treated arguments. Some
demonstration activities are planned.
Assessment methods and criteria
The students who constantly attend the lessons and get a pass on the
infra annum tests, can take a simplified final exam. The others will have
to take a complete one which consists of a written and, if required, an
oral test.
