Plumber(Passbooks) (Career Examination Series) None Edition

Scored a 87 on the Plumbers DCAS test. This combined with the Union material is all you need to pass.

I studied this book daily, lots of good material in the book but when I took the civil service test none of the material referenced in the book appeared in the exam, the material in the book was good but nothing close to this material appeared in the civil service exam I was really disappointed because I really needed this job after months of studying this book I didn't score high enough on the test. :-(
