## Teaching methods

Teaching activities will be carried out via slide-based lessons and written exercises. Slides will be uploaded on the Elly platform once a week. To download the slides it is necessary that students subscribes to the platform. Slides are considered integral part of the teaching material.

## Assessment methods and criteria

Written examination, built of 5 exercises, two of which are theoretical questions. Each of the five exercises is worth 6 points, when correctly solved. Also partial solutions will be evaluated
