At the end of the course students will possess and will be able to use the main mathematical tools, suitable to business, economic, financial and statistical applications. Basic mathematical notions, being already known to students since faced during every upper secondary school, are assumed to be preparatory to the course. For a sake of completeness and uniformity, preparatory topics are again considered during lectures. The course is organized in face-to-face lectures and exercise sessions.Some topics, being already known to students since faced during every upper secondary school, are assumed to be preparatory to the course. For a sake of completeness and uniformity, preparatory topics are again considered during lectures. Besides teaching and exercise hours, there will be extra hours of teaching support – mainly finalized to training for the written exam and to filling possible knowledge gaps – given either in lecture form or as individual meetings. Such activity will tentatively start at the beginning of October. Besides teaching and exercise hours, there will be extra hours of teaching support – mainly finalized to training for the written exam and to filling possible knowledge gaps – given either in lecture form or as individual meetings. Such activity will tentatively start at the beginning of October.The exam can be taken in two alternative modalities (a) and (b) explained below.In every case, the student must bring his university id card during the exam.(a) Standard exam:The exam is organized in a written test, including also theoretical questions, and in an oral test.A student is admitted to the oral test in case his mark in the written test is greater or equal to 15/30. The evaluation of the written test can be confirmed, after a discussion on the correction of the written test, if the mark is between 18/30 and 26/30.Students with a mark in the written test between 15/30 and 17/30 and those with a mark greater or equal to 27/30 must take the oral test. Every student passing the written test can anyway take the oral test.The discussion of the written test or the oral test must be taken before February, if the written test has been taken during the winter term (January-February) and before September if the written test has been taken during the summer term (June-July-September).A student not passing the written or oral test can take the next examination in the same term.(b) Exam in the form of an intermediate written test and a completion written test:For interested students, there is the opportunity to take an intermediate written test, during the teaching break, covering the first part of the programme. Passing the intermediate written test guarantees the access to a completion written test that will take place during the first examination date of the winter term in January.The intermediate and completion written tests are unique. Such tests are passed if the mark in both of them is greater or equal to 15/30. Students not passing either the intermediate or completion written test can take the exam according to the standard modality (a), during the first available examination date.Both the intermediate and completion written tests are not limited to students attending the first year.Students passing both tests with an average mark (rounded by ceiling) which is sufficient (= 18/30), can skip the oral test, getting as final evaluation the average of the two marks.Every student passing the written tests (intermediate and completion), can anyway take the oral exam.In any case, students must take the oral exam in the following two cases:• If the average of the marks in the intermediate and completion written tests is = 27/30;• If the average of the marks in the intermediate and completion written tests is 15, 16 or 17.The registration to the intermediate written test and the standard written test must be through the site: https://unipg.esse3.cineca.it/Home.doTeaching material, old written tests and other information on the course are available in the UniStudium page of the course.Information on facilities for special needs students are available at the link https://www.unipg.it/en/international-students/general-information/facilities-for-special-needs-studentsThe above modalities are subject to possible changes due to University guidelines following the COVID-19 emergency. 1.
