The wrong turns that cost marks, the recognition cues and routines for each question pattern, and a last-day sheet of formulas, anchor numbers and checks.
The common wrong intuitions across the Operating Systems pack, one row each: the wrong belief, the correct rule, and the check or consequence to remember, grouped from system calls and processes through synchronization, deadlock, scheduling, memory, virtual memory, files and disks, with a link to the sheet that explains each rule.
A partial preview of the top of the sheet. The full sheet is in the Operating Systems cheat sheet pack.
The recurring Operating Systems question patterns, each with its recognition cue, the first step and method, the check that can change the answer, and the usual failure, with a pointer to the sheet that holds the routine and the solved past questions in the pack; followed by a generic routine for any numerical OS question.

A one-page summary of the Operating Systems pack: the essential formulas with their conditions for scheduling, deadlock, paging, access time, files and disks; the key one-line facts for processes, threads, synchronization and memory; replacement policies and Belady; anchor numbers from the solved past questions; and the checks to run before marking an answer.
