CFA is an annual event of a global acceptance set up by Association for Investment Management and Research (AIMR) in the US. Its first exam was held in 1963, in which only 278 male candidates and 6 female participated. Now it has turned out a world program with the fastest growing candidate number.

It's no easy job to obtain a CFA certificate. Candidates are required to pass three level exams of total 6 hours within three years, including assets evaluation, economics, portfolio management and professional integrity. Each subject usually demands 250 hours study and questions are put in the form of case study, essay, multiple-choice and item-set.
