CIMA OCS past questions by topic

Every sub-task set in the last 3 Operational Case Study pre-seens CIMA has published materials for, summarised in our own words and sorted by core activity.

Topic map

How often each topic came up across all 200 OCS sub-tasks in the 3 sittings we cover. These are patterns from past exams, not a forecast: CIMA can test any part of the syllabus.

Topics by sitting

Sub-tasks on each OCS topic in each sitting, oldest sitting first. The number is in every cell; darker cells mean more sub-tasks.

Key (sub-tasks per cell):

How Eighty Marks works on it

Three past OCS tasks, each matched to a practice task on the same topic in our question bank, with an illustrative marked answer: a scaled estimate out of 150 against the pass line of 80, the four elements, and the one thing to fix first.

PASS LINE 80 · ABOVE

  • Technical understandingStrong: ZBB steps explained
  • Use of the informationGood: tied to the support teams
  • Application to the scenarioNeeds work: no mention of staff reaction
  • CommunicationFair: clear recommendation

Fix first: Say who builds the decision packages and how managers will feel justifying every cost from zero.

Sample: an invented mark to show the shape of our feedback, not a real student's. Our marks follow CIMA's published 2026–27 marking approach. They are a practice estimate to help you improve, not an official CIMA mark or a prediction of your result.
