The main exercises are given in the course code repository, https://github.com/fmontesi/cp2016, in the folder exercises. Each week has its own subdirectory.
If you would like to receive updates on when exercises become available, you can watch the repository on GitHub: open the link and click "Watch" on the top-right. (You need to create a GitHub account to do that, if you do not have one already.)
Some exercises are given at the end of the slides. More exercises are developed during the exercise classes, by reworking the examples in the book. Below you can find the reading assignments for each exercise class (see the Introduction slides if you do not understand this point).
