Industry data suggests 7-20 attempts on average before passing. At a 10% pass rate, the expected number is 10 attempts. At 15%, about 7 attempts. At 5%, 20 attempts. This translates to total costs of $2,100-$6,000+ depending on the challenge fee. Many traders underestimate this number because they expect to pass on the first try. Fewer than 5% of traders pass their first ever challenge.
