Sample Part 3 - Internal Audit Function study sequence
Select a stage to see its purpose. This is not an official timetable. Repeat or shorten stages according to your baseline, work calendar, and timed practice results.
Internal Audit Operations
Weight 25%. Studying only engagement fieldwork from older Part 2 materials and missing the 2025 Part 3 emphasis on function-level quality and results monitoring.
Keep your primary course aligned with the current syllabus, then use practice evidence to decide whether this stage needs more repetition.
Where CIA practice should focus
Three high-leverage drills. If practice time is short, start here.
Standards application stems
Ask which Standard or principle governs the scenario. Number recall without application underperforms.
Engagement planning decisions
Practise objectives, scope, and resource choices before fieldwork technique drills.
Results monitoring and quality
Part 3 puts heavy weight on engagement results and monitoring. Build scenarios around follow-up and QAIP.

How to read a CIA engagement-planning stem
Setup
A Part 2 question describes a new system implementation, management’s requested advisory scope, and a residual assurance need. Choices differ on how to set objectives.
How to read it
Separate advisory from assurance before you pick procedures. The keyed answer usually follows from the engagement’s purpose and risk focus, not from a favourite audit technique.
Takeaway
CIA Part 2 rewards planning logic. Procedures come after purpose.

Likely cause
Content reshuffle under the 2025 syllabus.
Next step
Print the 2025 domain map and re-file every note under the new part titles.
Part 2 fieldwork feels fine but scores lag
Likely cause
Under-studying Engagement Planning’s 50% weight.
Next step
Make planning scenarios half of every Part 2 study block.
Part 3 feels unfamiliar
Likely cause
Still studying old business-acumen topics as if they were Part 3.
Next step
Switch to function operations, quality, and results monitoring drills.
