If you wants to purse your career as financial analyst then CA is a very nice degree, which can serve your purpose very well.
My brother is in final module therefore i have little knowledge about CA. ICAP is currently passing through an evolution. They are introducing standard books, proper course outline, questions bank and converting initial four modules into three levels. On clearing each level you will get a certificate.
CA has its own charm but it is extremely difficult. If you don't have any financial responsibility or problem and you are consistent and persistent then go for it but keep in mind, you may have to suffer some serious blow from ICAP... just keep moving and don't get tired.
Good Luck (Y)
