How to study

Focus on audit judgement, not memorisation only.

  • Learn Clause 4 to Clause 10 intent, evidence, and common nonconformity situations.
  • Prioritise risk assessment, risk treatment, Statement of Applicability, and residual risk approval.
  • Practice identifying audit objective, scope, criteria, evidence, finding, and conclusion.
  • For nonconformities, link the problem, objective evidence, and requirement clearly.
  • Use practice papers after reviewing the documents to test scenario judgement.
