After reading through about half this book, I have already seen many answers to those engineering questions I have had in the past.

I would highly recommend this book - not only as a study guide for the test, but also as a reference source and even a best practices guide.

Thank you very much. I have purchased the exam preparation package for the exam and I passed it last week with ease.

Just another thank you. I recently purchased this exam and passed today with a high score and most of that was down to your study pack.
