CIMA consists of four levels: Certificate, Operational, Management, and Strategic Level. Each level consists of four tests, for a maximum of sixteen exams (all computer-based). The remaining three exams are pre-viewed based case study exams (Operational Case Study, or OCS, Management Case Study, or MCS, and Strategic Case Study, or SCS), which are held quarterly in February, May, August, and November. The remaining thirteen exams are on demand objective exams, lasting two hours each.
