Hi!
My understanding is the the CFAI infringed upon trademark of the CFA Institute. I do not believe the CFAI is in ANY WAY associated with the CFA Institute, which is the gold standard.
The CFA Institute offers exams throughout the world. Check out the website,
CFA Institute Home. I am sure that there is a test-taking center in India.
The CFA Curriculum is quite rigorous, but it is very good. Well, the entire investment research industry is highly competitive (and highly paid) (at least in the US).
Good luck!
Kevin
