Query: Worst book ever DO NOT USE-does not help

This book does not cover much of what is on the test. I was so upset and very dissapointed I studied this book over and over and I passed the practice exam at the end of the book. I went to take the test and the questions that were asked were not covered in the book. The last two chapeters are not even on the exam. DO NOT WASTE YOUR MONEY!!! Now I have to stay an extra semster!!! Please do not buy this book. Just looked at the title page and it has not been updated since 1991!!! This book is neither credible or reliable. The people at Comex systems should be charged for fraud!!
