I read this book from cover to cover and found so many errors it wasn't funny, thats pathetic. It does teach you about Access but it has not been proof read, certain questions in the book and on the CD are blatently incorrect and are also contradictory. After averaging above 98% on the practice exam on the CD, I thought I was ready for the real thing but ended up failing. I bought another Access book and studied a bit more and then passed, no thanks to this guide. If you don't mind studying material and answers which are wrong then buy this book.
