What is ICWA ? Is it similar to CA ?

Go for CA instead of CWA as both would require similar efforts but CA is well established profession than CWA. Also a CA can do most of the work of CWA but a CWA can't.

CWA ia also a professional course like CA It has one or two common subjects like company accounts but rest is totally different Cost accountant can conduct cost audit of manufacturing and service companies it can even conduct compliance check in few cases Scope was very less for CWA before but now
