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.

How we band topics
  • Sittings: 2 points if the topic came up in every sitting we cover, 1 point if it came up in more than one.
  • Variants: 2 points if it came up in at least half of the exam variants, 1 point if in at least a quarter.
  • Blueprint: 1 point if its core activity has the top time weighting at the level. Where every core activity has the same weighting, nobody gets this point.
  • 4 or more points is "Often tested", 2 or 3 is "Sometimes tested", and fewer is "Rarely tested".
  • "Fits this pre-seen" is separate: it shows when the pre-seen's industry or key themes use words linked to the topic (our summary stands in until key themes are written).

It is a count of what CIMA has asked before, not a forecast. Any part of the syllabus can come up.

Core activities against the blueprint

Each core activity's share of the 200 sub-tasks, next to its blueprint weighting. The blueprint weights exam time and sub-tasks vary in length, so treat this as a rough check.

  • A CostingWithin range

    13% of sub-tasks (25) · blueprint 12–18% of exam time

  • B BudgetingWithin range

  • C PerformanceWithin range

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 score out of 150 against the pass line of 80, the four competencies, and the one thing to fix first.

The past task

Zero-based budgeting for support costs

OCS · Nov 2025 & Feb 2026 · SumTrix · V6 · Task 3(b) · Core activity B (Budgeting)

Benefits and challenges of ZBB for support activity costs.

88 / 150

PASS LINE 80 · ABOVE

  • TechnicalStrong: ZBB steps explained
  • BusinessGood: tied to the support teams
  • PeopleNeeds work: no mention of staff reaction
  • LeadershipFair: clear recommendation

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