puppify, google cfa institute's website for the authentic info. so far i have heard, you need to have lot of patience to pass all three levels of exams successively. Only to pass these exams will require about three years, plus two more years of experience in the industry to get a cfa charter. There are several volumes of "dhaddu kitaps" on different topics, such as fixed income, corporate finance, portfolio managment, ethics, economics, quantitative methods, financial accounting, etc. If you pass all three levels, the payoff is very good. The average annual wages after cfa is around $125k.
