Getting Started: The Diagnostic Exam
The following problems refer to different chapters in the book. The important thing is
not whether you get the correct answer, but whether you have difficulty with one or more
questions from a chapter. If so, then review the material in that chapter. You may use a
calculator and periodic table. For each question, circle the letter of your choice.
