Query: Beware

Beware of books in this series. I just finished taking the Custodian I and II exams in Central New York ( March, 2008 ) - 90 questions. I bought the "School Custodian" test prep book ( horribly outdated ), the "Junior Building Custodian" and the "Custodian" books ( interesting but not relevant nor helpful for the test ) and I was ill prepared for the test based on my purchases.
