Attendance	0%

There are ten quizzes in Weeks 3-7 and 9-13, and five take-home assignments in Weeks 2-6.
Written exams are handwritten, allow no electronic devices, and last one hour.
The team-based term project begins in Week 9. Teams of 3-4 design and develop an OS prototype, prepare a specification and project report, and present in person in Week 14.
The term project grade is split evenly between instructor and peer evaluation.

Generative AI tools are permitted and encouraged for assignments and the term project. Students must explain their own reasoning and design decisions.
A grade is not awarded if a student misses more than one third of the total class hours.

Each week's slides were distributed as a lecture deck (W##_LEC_) and a lab deck (W##_LAB_), and they are organized in the Week## unit of the same number as Concepts_Lecture and Concepts_Lab, respectively. The units are listed in the Lecture-Notes index.
Weeks 7 and 14 have no lab deck, and no lab notes were made for the lab decks of Weeks 9-13 (W09_LAB_Sleep-Wakeup-And-Pipes, W10_LAB_Deadlocks, W11_LAB_Page-Tables, W12_LAB_COW-Fork-And-Lazy-Allocation, W13_LAB_File-System-Internals).
Security and protection was planned for Week 13, but its slides were distributed as a Week 14 deck (W14_LEC_Security-And-Protection), so it is organized in the Week14 unit.
HW1-HW5 are the take-home assignments of Weeks 2-6 and are listed in the Coursework index.
