Best course in our field other than ca,cma,cs

CFA or CPA of USA.

Depends upon ur area of interest...CPA has no value in INDIA..If u wana settle down abroad..or work abroad..then only do the CPA of that country....Ca and CFA are not related to each other at all....if u wana enter into the field of core finance,.,,,go for international CFA and FRM..if u wana enter into taxation..no need to do any other course....If u wana do business..do MBA.
Best of Luck.
