The programming part of the exam can be performed by doing an assignment.

Assignments are reserved only for students attending the course the first time this semester.

Students have to send an application for the assignment to riccardo.sisto [at] polito.it and stefano.scanzio [at] polito.it within 29 April, 2024. The application must contain a curriculum, which has to include the known software and the list of passed exams, both master and bachelor degrees, with the related scores. In addition, students have to provide the list of assignments they are interested in, sorted by preference (most preferred first). The allocation of the assignments to students will be communicated within 03 May, 2024. Possibly, depending on the curriculum or on the number of requests, some requests may not be accepted.

The file with the list of assignments can be found under “Materiale Didattico 2023/24” in Portale della Didattica in the file “assignments_2023-2024.pdf”.
