Introduction

Welcome to 1,001 Praxis Core Practice Questions For Dummies. Don’t take the dummies thing literally — you’re obviously smart and capable. You’ve chosen to shape the minds of future generations through education. And on that quest, you will encounter obstacles. At least one of those is a Praxis exam.

This book is designed to give you lots of exposure to the kinds of questions you’ll see on the very first test for teachers: the Praxis Core Academic Skills for Educators exam (referred to as Praxis or Praxis Core from here on). To clear this hurdle, you need some practice and pointers on how best to answer the questions. This book provides that and more: It goes beyond providing relevant practice questions by showing simple and effective ways to solve challenging Praxis problems.

What You’ll Find

The Praxis Core practice problems in this book are divided into four chapters based on skills involving Math, Reading, Writing, and Essays. Questions are adjusted and repeated to give you practice and mastery. If you struggle with one question, you can find a group of similar questions to practice and hone your skills. This book serves as an effective standalone refresher of Praxis basics or as an excellent companion to the latest edition of Praxis Core For Dummies (Wiley). Either way, this book helps you identify subject areas you need to work on so you can practice them until you’re a pro and thus prepare for test day.

If you get a problem wrong, don’t just read the answer explanation and move on. Instead, come back to the problem and solve it again, this time avoiding the mistake you made the first time. This is how you improve your skills and figure out how to solve the problems correctly and easily.

Whatever you do, stay positive. The challenging problems in this book aren’t meant to discourage you; they’re meant to show you how to solve and master them.

How This Book Is Organized

The first part of this book gives you questions covering math, reading, and writing. All the answers and explanations are in the second part of the book.

The math subtest covers the following topics:

The reading questions in this book cover the following topics:

On the writing subtest, you find these types of questions:

As part of the writing subtest, you’ll also be required to demonstrate knowledge and research skills by writing two essays based on information presented. One is an argumentative essay; the other is an explanation of a topic.

Beyond the Book

Your purchase of this book gives you so much more than a thousand (and one) problems to work on to improve your skills with the Praxis Core. It also comes with a free, one-year subscription to hundreds of practice questions online. Not only can you access this digital content anytime you want, on whichever device is available to you, but you can also track your progress and view personalized reports that show which concepts you need to study the most.

What you’ll find online

The online practice that comes free with this book offers you the same questions and answers that are available here. Of course, the real beauty of the online problems is your ability to customize your practice. In other words, you get to choose the types of problems and the number of problems you want to tackle. The online program tracks how many questions you answer correctly or incorrectly so that you can get an immediate sense of which topics require more of your attention.
