Authors’ Acknowledgments

Thanks to acquisitions editor Erin Calligan Mooney, who chose us to author this book and ironed out all the preliminary details to make this book possible.

Tim Gallan, our project editor, deserves a loud cheer for serving as a gifted and patient collaborator and editor — shuffling chapters back and forth, shepherding the text and graphics through production, making sure any technical issues were properly resolved, and serving as the unofficial quality control manager. Christine Pingleton and Jessica Smith, copy editors, earn editors of the year awards for ferreting out our typos, misspellings, grammatical errors, and other language foe paws (or is it faux pas?), in addition to assisting Tim as reader advocates. We also tip our collective hat to the production crew for doing such an outstanding job of transforming an enormous hodgepodge of text, equations, and images into such an attractive bound book.

Introduction

You’ve set your sites on becoming an officer in the armed forces. Congratulations! Your fellow citizens extend a big thank you as well. Not everyone has the fortitude and confidence to step into a leadership position. To become an officer, however, you need to prove yourself, and one of the first hurdles you must clear is one of the Officer Candidate Tests (OCT) — any of several tests required for admission into Officer Candidate School or Officer Candidate Training.

To do well on the test, you need the knowledge and skills you acquired (or should have acquired) in high school. You must be able to make sense of what you read and pick out key details and ideas from reading passages; prove that you have a solid vocabulary and know how to use it, both in speaking and in writing; be a whiz at basic math, including geometry and algebra; have a firm grasp of general science, including the life sciences, chemistry, and earth sciences; and, depending on the test, have the ability to solve problems related to mechanics and electronics.

Don’t worry. You probably knew a lot of what you need to know on the test at some point in your life. So a refresher course and some practice should be sufficient to tone your brain cells and hone your skills. We’re here to help. This book provides you with everything you need to know along with test-taking strategies and tips for doing your very best when test day rolls around.

About This Book

Officer Candidate Tests For Dummies is for smart, highly motivated individuals like yourself who need to get up to speed in a hurry in a few key subject areas and need to sharpen your skills for test day. We carefully constructed this book to cover the fundamentals you’re most likely to encounter on the test in easily digestible chapters and sections. You don’t even need to read the book from cover to cover. Just flip, skip, and dip into the chapters and sections you need most. Throughout the book, we provide

check.png Lots of how-to guidance explaining how to read effectively, build vocabulary, solve mathematical problems (even word problems), and think logically.

check.png Sample questions that test you along the way so you can develop confidence through practice.

check.png Insight into what’s covered on each OCT subtest.

check.png Strategies and tips for reading and understanding questions and choosing the correct answers most efficiently.

check.png Guidance on how to prepare for test day so you feel less anxious and more confident knowing what to expect.

check.png Several complete, timed practice tests so you gain experience taking tests when the clock’s ticking.

check.png Answers and explanations to identify your weaknesses and learn from your mistakes.

Conventions Used in This Book

Although we don’t like to think of our book as conventional, we follow several conventions throughout to make the information more accessible:

check.png We use italics both to stress important words and to highlight words we define. Spot an unfamiliar word in italics, and you’re almost guaranteed to find its meaning in the next sentence or the one after that.

check.png We use bold text to highlight keywords in bulleted lists, the action parts of numbered steps, and the correct answers in our answer keys.

check.png We use monofont for Web addresses. Keep in mind that some Web addresses may extend to two lines of text. If you use one of these addresses, just type the address exactly as you see it, pretending that the line break isn’t there.

What You’re Not to Read

You may notice some text stuffed into gray boxes. These boxes, which are called sidebars, contain bonus information on topics we thought you might find educational or entertaining (hopefully both). While these sidebars are interesting, you don’t have to read them to do well on the test. So, if you’re short on time, feel free to skip them.

Foolish Assumptions

We assume you’re using this book in preparation for taking one of the OCT: the Armed Services Vocational Aptitude Battery (ASVAB), the Air Force Officer Qualifying Test (AFOQT), or the Aviation Selection Test Battery Officer Aptitude Rating (ATSB OAR). If that’s a false assumption, you’re in the wrong class. We also assume that you’re a highly motivated student. You want to learn, you want to do well on the test, and you’re willing to invest the time and effort in gathering information and building the requisite skills. You may have just graduated from high school or college, or you may have been out of school for some time. That doesn’t matter. What matters is that you want to learn and succeed.

How This Book Is Organized

This book is divided into five parts to make the information more manageable. For example, if you typically do better in math and science than in English, you probably want to spend more time in Part II brushing up on vocabulary and practicing your reading skills. The following sections function as a road map, briefly describing the contents of each part so you have a clear idea of where you need to go first.

Part I: An Officer and a Test

Part I is basic training. Chapter 1 traces the various paths you may follow from point A to point B — from where you are right now to where you want to be as an officer in the military. Chapter 2 answers the all-important question: What’s on the test? It describes the different OCT, the subtests that comprise the OCT, and the number of questions and amount of time you have to complete each subtest. Finally, in Chapter 3, we reveal numerous test-taking strategies and tips to improve your performance on any standardized test.

Part II: Getting Schooled in English

The chapters in Part II provide guidance on how to strengthen your word skills and tips on how to assess the meaning of words from common roots, prefixes, and suffixes. We also show you how to identify the main idea in a reading passage, pick key facts and figures out of paragraphs, and infer the meaning of what you read from clues within paragraphs. These chapters provide plenty of practice questions so you know exactly what to expect on test day and how to approach the different English sections of the tests.

Part III: Back to School with Math and Science

Part III is what most people consider the geeky part of the book. Here you refresh your memory and sharpen your skills in basic mathematics, geometry, algebra, general sciences, mechanics, and electronics. Basic mathematics covers a lot of ground — everything from whole numbers, fractions, and decimals to roots, radicals, quadratic equations, and geometry. We even help you figure out how to solve those pesky word problems that nobody likes.

This part also covers the general sciences, including biology, chemistry, geology, astronomy, human anatomy, and more. We also bring you up to speed in a hurry on the mechanics and electronics portions of the OCT so you have a clear idea of what to expect on the test. We can’t possibly cover everything you may encounter, but we can give you a solid foundation for fielding the most common questions and figuring out the answers to less common ones.

Part IV: Practice Tests

This part features four practice tests:

check.png The Air Force Officers Qualifying Test (AFOQT)

check.png The Aviation Selection Test Battery Officer Aptitude Rating (ASTB OAR)

check.png The Armed Services Vocational Aptitude Battery General Technical (ASVAB GT)

check.png The Armed Services Vocational Aptitude Battery Marine Officer Candidate School (ASVAB Marine OCS)

By taking these tests, you discover your strengths and weaknesses, learn how to pace yourself, get a better feel for what’s on the test so you’re better equipped to answer different types of questions, and sharpen your problem-solving skills for test day. Practice is essential in improving memory recall and critical thinking skills, and this part provides plenty of problems to run through.

Part V: The Part of Tens

No For Dummies book would be complete without a Part of Tens. In this quick and easy part, we give you tips for studying well and strategies for dealing with multiple-choice questions. By improving memory retention and knowing how to answer multiple-choice questions more accurately and efficiently, you have the tools you need to achieve peak performance.

Icons Used in This Book

Throughout this book, you’ll notice icons in the margins. These icons flag important information to take note of. Here’s what they mean:

remember.eps This icon highlights the most important information and insights in the book. In short, this material should be read and applied often.

tip.eps Strategy is no substitute for knowledge and skills, but it certainly can help you answer questions faster and with greater accuracy. So when you see this icon, you know you’re staring at one of our tips to improve your performance.

warning_bomb.eps The test is peppered with pitfalls, and we’re here to point them out and steer you clear of them. Look for the Warning icon to spot trouble before it sinks you on the test.

example_gre.eps We believe that the best two ways to learn anything is by viewing and doing — seeing how it’s done and doing it yourself. We use the Example icon to flag these opportunities for you to practice what you’ve learned.

Where to Go from Here

Where to go from here really depends on you. To get the most out of this book, we recommend reading it from cover to cover. However, you may take a different approach, and this book is structured in a way that makes it conducive to a variety of study methods.

For example, you may want to take one of the practice tests in Part IV first, sort of as a diagnostic tool to identify your weak and strong subject areas. You may then focus more of your efforts on chapters related to your weakest subjects. If you choose to take a test as a way to get a baseline of your skills, consider reading Chapter 3 first to improve your performance without having to spend time exploring specific subject areas.

Another option is to warm up with material you already firmly grasp and then work up to more challenging subjects. For example, if you’re confident in your vocabulary and reading skills, start with the chapters in Part II and then work on your weaker areas. Also, if you’re familiar with a given subject area and don’t want to spend a great deal of time reviewing what you already know, consider skimming the chapter for tips and warnings. And be sure to check out the examples to improve your performance without acquiring new knowledge or skills.

Part I

An Officer and a Test

9780470598764 pp0101.eps

In this part . . .

Consider Part I to be your basic training for the Officer Candidate Tests. Here, we show you how to go from Point A to Point B: from where you are right now to the point at which you become a bona fide officer. We bring you up to speed on the tests you’ll be taking so you know what to expect. And we reveal valuable test-taking tips and strategies that’ll pay handsome dividends when test time rolls around.

Don’t get us wrong. You still have a lot of preparation ahead of you before you’re ready to ace the test, but this part sets a solid foundation on which to build your knowledge, skills, and confidence.

By the way, Chapter 1 presents some general information that you’re unlikely to encounter on any of the tests. It does, however, give you an idea of some of the basics you’ll run into in the military environment relating to structure, pay and benefits, and occupational specialties as well as links to more information.
