Well..... I can introduce ACMA but the rest of the answer is a very detailed one
ACMA stands for Associate Chartered Management Accountant
ICMAP (Institute of Chartered Management Accountants) conduct its exams etc
One can only start ICMA after Bachelors degree. This is the minimum requirement.
If you pass is without any fails then you can complete it in 2.5 years.
You need 3 years of experience in management accounting + passing all papers to get the title ACMA
Now the practical side
Its papers are extremely hard & difficult to pass. ACMA's market value has also gone down a lot in the past. I personally think that the result is way too less then the effort one has to do in ACMA. So it wud be a better option to do ACCA or CA rather than ACMA
But if you are insistent on doing ACMA, then there is a more easier route of gaining the degree qualification
Do CIMA ( A UK based qual like ACCA, it can be done in Pakistan) After passing all papers of CIMA (which is much much more easier than ICMA) & gaining 3 years of experience in management accounting you will become the member of CIMA. All the members of CIMA are eligible to apply for the qualification of ACMA of ICMAP. Just apply, you will get all the papers of ACMA exempted + the practical experience requirement exempted.
