Half the people who take any CFA exam fail.
However, anybody can pass all levels without being a Wall Street superstar nor a genius. All you need is some time to invest, a sensible strategy, and a strong commitment.
I am a 27-year-old risk manager in a large international bank, and I spent the past three years compiling the most comprehensive strategy I could to maximise the CFA exam pass probability relative to time invested. Over this period, I passed all three CFA exams (including failing Level III on my first try) and both exams of the FRM programme while also working full time. I also took a series of other exams over the same period, which brought me additional insights on how to study efficiently. It is against this background that I developed the guide below on how to optimally prepare for CFA-like exams. Though I originally wrote it for myself, I believe that this guide can help many other exam takers.
