A Note from Series Editor Ed Tittel
You know better than to trust your certification preparation to just
anybody. That’s why you, and more than two million others, have
purchased an Exam Cram book. As Series Editor for the new and
improved Exam Cram2 series, I have worked with the staff at Que Certification to
ensure you won’t be disappointed. That’s why we’ve taken the world’s best-selling
certification product—a finalist for “Best Study Guide” in a CertCities reader poll
in 2002—and made it even better.
As a “Favorite Study Guide Author” finalist in a 2002 poll of
CertCities readers, I know the value of good books. You’ll be
impressed with Que Certification’s stringent review process,
which ensures the books are high-quality, relevant, and
technically accurate. Rest assured that at least a dozen industry
experts—including the panel of certification experts at
CramSession—have reviewed this material, helping us deliver an
excellent solution to your exam preparation needs.
We’ve also added a preview edition of PrepLogic’s powerful, full-featured test
engine, which is trusted by certification students throughout the world.
As a 20-year-plus veteran of the computing industry and the original creator and
editor of the Exam Cram series, I’ve brought my IT experience to bear on these
books. During my tenure at Novell from 1989 to 1994, I worked with and around
its excellent education and certification department. This experience helped push
my writing and teaching activities heavily in the certification direction. Since then,
I’ve worked on more than 70 certification-related books, and I write about
certification topics for numerous Web sites and for Certification magazine.
In 1996, while studying for various MCP exams, I became frustrated with the
huge, unwieldy study guides that were the only preparation tools available. As an
experienced IT professional and former instructor, I wanted “nothing but the facts”
necessary to prepare for the exams. From this impetus, Exam Cram emerged in
1997. It quickly became the best-selling computer book series since “ …For
Dummies ,” and the best-selling certification book series ever. By maintaining an
intense focus on subject matter, tracking errata and updates quickly, and following
the certification market closely, Exam Cram was able to establish the dominant
position in cert prep books.
You will not be disappointed in your decision to purchase this book. If you are,
please contact me at etittel@jump.net. All suggestions, ideas, input, or constructive
criticism are welcome!
