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.
The evaluation consists of two components: two midterm tests concerning the theoretical and applied knowledge. The final classification is the average of the grades in each component, or in the case of fail, it will be the grade of the final exam.
