Class exercises concern with simple problem solving activities, in strict correlation with the theoretical lectures.
In some cases scientific calculators (students' personal property) may be required.

The exam is organized in three parts.
Part 1 will consists of a test based on questions. A threshold mark is required to get through to the second part.
Part 2 will consist of exercises to be solved. A threshold mark is required to get through to the third part.
Part 3 will consist of an oral discussion on subjects taken from the syllabus.
Each part will contribute at most 10 points to the final mark, which will be obtained as the arithmetic sum of the 3 marks
Each of the following situations leads to exam failure:
- part 1 mark < 4.5
- part 2 mark < 4.5
- part 3 mark < 6

The exam is organized in the following three parts (total duration: 90 minutes). No notes or other material can be used except for blank sheets, a pen and a non-programmable calculator.
