Hello Aspirant:

Students who have passed 10+2 are eligible for the CMA Foundation exam. The Institute of Cost Accountants of India conducts CMA Foundation exam two times in a year in the months of  June and December. If you have passed the CMA Foundation exam, then you are eligible for CMA Inter. If you have any graduate degree, you are exempted from ICMAI Foundation exams. You can directly enter into CMA Inter. After CMA Inter, you need to appear for CMA Final.

The minimum duration needed to complete CMA is 2 year's. But it depends upon how fast the student is able to clear his papers.

All the best
