A good portion of the AP Chemistry Test deals with calculations, either with or without the aid of a calculator. For all of these problems, there are two different components—the chemistry component and the math component. Most of this book is devoted to a review of the chemistry component of the problems, but this chapter is designed to review a few important mathematical skills that you will need to know as you work through the problems. Three skills that are critical to success on the AP Chemistry Test use significant figures, scientific notation, and dimensional analysis. 

In the second portion of this chapter, we will review laboratory equipment. In addition to an occasional question about laboratory procedure, the AP test now contains an essay or problem question that is entirely devoted to laboratory procedure. The College Board has a recommended series of labs, many of which you should have completed prior to taking the test, and the test will contain a description of one of these labs for you to analyze. In this book, you will find information about these labs in the chapters that correspond to their subject. The College Board also recommends that you should be familiar with a variety of laboratory equipment. So, in the last part of this chapter, you will find a list (Table 3.1) of the recommended labs as well as diagrams of the lab equipment. Make yourself familiar with the equipment by name and function.

Each handbook contains an abstract, a foreword, an overview, learning objectives, and text material, and is divided into modules so that content and order may be modified by individual DOE contractors to suit their specific training needs. Each subject area is supported by a separate examination bank with an answer key.
