過關率超過90% !? (2004/10/13 上午 11:23:07 )
Too good to be true，統計學上站不住腳，引用cfai副總裁在Professional Investor (Feb 2004)的話: "...Some prep providers even advertise pass rates in the high 80% and low 90% range. Given that the majority of candidates are availing themselves of prep courses, and the worldwide pass rates were 42%, 47%, and 68% for Level I, II, and III, respectively, it seems rather odd that all these prep courses are advistising such high success rates!" |
