The book is based on over twenty years of experience teaching hundreds of students who have successfully passed certification examinations at both technician and technologist levels. Use of this book alone, however, does not guarantee a passing score. Readers are encouraged to consult appropriate textbooks to add to their understanding of topics.
No attempt was made to simulate examination questions. The book is written in rapid-fire question/answer format, without distracters that may be mistakenly assimilated as the correct answer. Readers are challenged to generate their own answer rather than choosing one based on recognition or guessing. The two check boxes next to each question are a time-management aid that enable the reader to keep track of correct and incorrect answers and quickly identify topics that require further study. Many of the answers provide additional information beyond what was requested in the question. These questions and answers provide a review of the knowledge base required to answer typical examination questions.
