Teaching method
In the theoretical and practical lectures, it will be explained and discussed the successive topics of the course program. The topics are introduced by the teacher, consolidated using as much as possible with real examples drawn from the insurance industry, followed by a brief discussion and use of computational means to support problem solving.
Evaluation method
Two tests, to be carried out during the academic period and exam (s) according to the academic calendar.
Each of the tests has a weight of 40% for the calculation of the final grade, being exempt from examination the student who has a weighted average greater than or equal to 9.5, with both tests graded at least 7.5 values.
A workgroup with report delivery and discussion with a weight of 20% of the grade.
All elements (2 tests and group assignment) are mandatory for exam waiver.
Presential tests and exams, with consultation of all paper-based material (open-book) that students want to use. If there is a component that requires computer support, students will be able to use their pc or pc in the laboratory, without access to the internet.
