Exam: Written test; Group project; Computer-based written test in class using POLITO platform;

The exam consists in a written (150 min) part with exercises/questions on theoretical and practical aspects of the course. The exam is split in two parts (that can be taken at different dates): - operating system internals - system calls and concurrent programming Both parts of the exam verify the related expected learning outcomes in terms of knowledge as well as skills. A sufficient grade is required in both parts. The final grade is obtained by summing the grades of the two parts (maximun grade for each part: 13, maximun total grade: 26). A final optional (group) project, on either of the two course parts, can ad an extra (up to 6) grade. A final total grade of 31 or 32 is converted to 30 cum laude. The optional project mainly verifies the expected learning outcomes in terms of skills.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
