I think you have valid concerns with the questions. It is true that some errors can creep into the vetting process, no matter how diligent the review is. Sometimes the question is just faulty, other times it's due to changing circumstance. I think that only the LPI statisticians are truly in a position to evaluate the percentage errors, so no comment from me on that aspect. What we can do as a community instead is to help make the next review a thorough one. People like yourself who have passed the certification and want to see the exam be better should sign up to be reviewers and examine each question multiple times. That way we can weed out the bad ones. Think of it this way - someone reviewed the questions before you wrote them so you could write a better exam that they did. You can return the favour to the next one in line. -- Alan McKinnon alan dot mckinnon at gmail dot com _______________________________________________ lpi-examdev mailing list [email protected] http://list.lpi.org/cgi-bin/mailman/listinfo/lpi-examdev
