Good pass rates are the result of the hard work of the participantsespecially in the weeks between the end of the Seminar and the exam itselfrather than the Seminar instructor.
For many years I posted detailed data for all my seminars (how many took each session and how many passed the exam at the following sitting), in comparison with the overall SoA/CAS pass rates, in the hope that other seminars would do the same and that this data would help people in choosing seminars. To my surprise, I was criticized (by a competitor in the seminar business) for posting information he considered misleading. As something of a knee-jerk liberal who believes that full disclosure is good for the consumer and the market, I was puzzled by this but decided to remove the detailed results from my website in 2009.
After a little more thought, I decided that it indeed might be misleading to show individual values of the pass ratesafter all, individual values of a random variable indicate little about its mean. But sample means are good estimators of the true mean, so I'll give you the following data:
in all my seminars for this exam since 2003, during which time the core material on so-called "loss models" has changed only slightly, the percentage of my seminar attendees who pass the exam at the sitting immediately following my seminar has averaged 1.12 times the worldwide pass rate released by the SOA and CAS.
