What is difference between ACCA/ACA/CIMA/ICAEWWatch this thread
CIMA is also a certified course mainly focusing on Management Side.
ICAEW (ACA) is a few steps ahead of CIMA and ACCA because it is a chartered accountancy Degree.
You need to decide what is your area of interest.
Perhaps, you can do ACCA first and after completing it you will get some exemptions from ICAEW, so you will just need to give the remaining papers.
The ICAEW course is generally seen as tougher than the ACCA and the earning potential is high. It is one of the most prestigious qualifications in the accounting world, opens doors and gives you an unbelievable network.
In many cases, employer covers part or all of the costs for these qualifications. A number of students also do degree apprenticeship for ICAEW. So you may even get paid while doing these qualifications.
