Theory lectures will be delivered using slides that will be made available to the students through the portal. Exercise lessons will be run in parallel to theory lectures. During them exercises will be solved of a similar level of difficulty of those proposed during the exams. In some cases scientific calculators (students' personal property) may be required.

You can take this exam before attending the course

Exam: Written test; Compulsory oral exam;

The exam is organized in two parts: written and oral. The written part consists of two quizzes and two exercises and lasts 90 minutes overall. Only a pocket calculator and a pen will be allowed. Blank sheets will be provided. A threshold mark is required to get through to the oral. The oral part consists of two questions on subjects taken form the syllabus. The marks are handled as follows: 1) each of the written parts awards a maximum of 5.5 points for a maximum total mark for the written part of 11 points 2) the oral part awards a maximum of 20 points (10 points for each question) 3) the final mark is the arithmetic addition of the written and the oral parts marks 4) each of the following situations leads to exam failure: - mark for one of the two written parts < 2.5 - total mark for the written part < 5.5 - mark for one of the oral questions < 6

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.
