Yes you can. Usually the course duration is 4 to 6 months (one semester’s duration) and a month later exams are held. The duration is flexible and depends on the enrolment date in a subject. The maximum amount of subjects you will be permitted to undertake is 4 per semester.

The exams are taken in a mutually agreed exam period between WITS and the student. For CMA and GMA subjects the usual exam period is May or November, and it will cost more for ICMA students wishing to sit for exams outside these scheduled times.

ICMA expects an exam to be taken within one-year of commencing a subject.
