ExploreAbout this exam
The ONECCA Examen d'Aptitude is the professional aptitude examination set by the Ordre National des Experts Comptables et Comptables Agréés du Cameroun. It is designed for candidates who aspire to become chartered accountants or statutory auditors in Cameroon and who already hold the required academic and professional training. The exam tests both technical mastery and professional judgement across financial accounting under SYSCOHADA and IFRS, management accounting, audit and ethics, Cameroonian tax law, OHADA business law, corporate finance, and information systems and governance. Expect a written examination that combines multiple-choice questions with essay-style case studies, so you must be able to compute, analyse, and explain. Preparation should be structured: first consolidate your grasp of SYSCOHADA and IFRS, then move to audit methodology and ISA standards, then tax and law, and finally integrate with case practice under time pressure. Work through past-style cases, practise writing clear conclusions, and keep up to date with official texts. The official body publishes the current format, calendar, fees, and pass requirements on its website; always check there for the definitive version before you register.

What you'll study
About ONECCA Examen d'Aptitude preparation
What is the format of the ONECCA aptitude exam?
The exam is written and typically combines multiple-choice questions with essay or case-study questions. The exact mix and weighting are set by ONECCA and can change, so consult the official ONECCA website for the current structure before you plan your revision.
How difficult is the exam?
It is a professional-level examination, so difficulty is high. You need both technical accuracy and the ability to apply standards to complex facts. Many candidates find the case studies demanding because they require structuring an answer, justifying treatments, and managing time across several domains.
Can I retake the exam if I fail?
Retake rules, including any limits on attempts or waiting periods, are set by ONECCA. They are not fixed here. Check the official ONECCA website or your registration documents for the current retake policy and any conditions that apply to your session.
How much time should I allow for preparation?
Most successful candidates prepare over several months. A realistic plan is to spend the first half of your preparation on core accounting and audit standards, then move to tax and law, and reserve the final weeks for integrated case practice under timed conditions. Adjust according to your background.
In what order should I study the domains?
Start with financial accounting (SYSCOHADA and IFRS) because it underpins audit and finance. Then study audit and ethics, followed by taxation and OHADA business law. Add management accounting and corporate finance, and finish with information systems and governance. Integrate with case practice throughout.
What are common failure modes?
Candidates often lose marks by misapplying SYSCOHADA or IFRS treatments, ignoring the precise wording of a standard, failing to structure essay answers, or running out of time. Weakness in one high-weight domain such as audit or accounting can also be decisive, so avoid neglecting any area.
Where can I find the official exam dates and fees?
The official body, ONECCA, publishes the exam calendar, registration fees, and any current pass requirements on its website. Because these details change, this page does not state them. Always confirm directly with ONECCA before making travel or payment arrangements.
Is the exam delivered in French or English?
Cameroon is bilingual, and ONECCA examinations are generally available in French and English. The language of your paper should be confirmed at registration. Technical terms such as ISA, SYSCOHADA, and IFRS are usually kept in their standard form in both versions.
