Please visit cfainstitute.org for specific details. you can also view the CFA specific thread in pagalguy.com
As far as the syllabus is concerned its more of Financial Management, Economics and Accounts which I believe a CA Inter student should not find difficult
Fees in Indian Currency for CFA Level 1 : ~ 55k ( Inclusive of one time registration, one time exam fee, and Study material). Every subsequent attempts would be around 30k (since 15~20k is registration fee which is already paid). You also receive discounts from the institute if you make the enroll yourself well in advance.
I would suggest you to get the study material online and see for yourself prior to enrolling for these heavy video classes and coaching institutes.
Please note all candidates should have a valid international pasport for entry into the exam hall.
Good luck!
