Free Study Guides for the Postal Service Exam™

These study guides have been revised to cover the Postal Service Exams™ #474, 475, 476, and 477 which are the tests now used for Post Office job applications (since April 1, 2019). Any preparation you find elsewhere for test #473 is now useless as that test is no longer given.

Having study guides for these tests is vital, since there are few specific skills to practice or study. Improving your chances of getting the highest score possible will be a matter of understanding the question type and becoming familiar with the different formats. These free study guides will help you in both of those areas.

Check for Errors

This is one of the two sections of the Postal Service Exam™ in which there are definite correct and incorrect answers possible. It is also one of the two sections in which quick completion might raise your score, so it’s worth it to try a little practice. For this reason, we have free practice questions and flashcards to help you. See what the Check for Errors test content is like by looking through this study guide. We really think it will help!

Describe Your Approach

This section contains many questions—56 of them—and is included in all four of the Postal Service Exams™: #474, 475, 476, and 477. The questions are about how you deal with people and how you would personally react in a given situation. Despite the large number of questions, it should only take you about 6 minutes to complete all of them, but there is no time limit. Like those in the Work Scenarios section, these questions do not have a “right” answer. Your choice will depend on your unique personality and methods of dealing with particular circumstances. Just quickly assess the given situation, and choose one answer that best matches how you would most likely react. Hopefully, this study guide will help you to be best prepared to answer the questions in this section.

Tell Us Your Story

All four of the Postal Service Exams™ (#474, 475, 476, and 477) include this section, which contains 20 questions that deal with your previous work experience. It should take you about 2 minutes to complete, but your time is not limited to this. It is important that your answers are consistent with any of the other information you provide the Post Office, including facts stated in your resume and any other sources of job history that may be accessible. Therefore, you’ll need to answer all of them honestly and accurately. This study guide will walk you through the process and help you become accustomed to the type of questions in this section.

Work Scenarios

This section is included in all four of the Postal Service Exams™: numbered 474, 475, 476, and 477, but it is called “Work Situations” on test #477. There are eight questions which should take you about 7 minutes to complete, but there is not a time limit. The questions address two things: the action you would be most likely to take and the action you would be least likely to take. This means you’ll select two answers for every question. Try not to spend time second-guessing yourself when answering. There is no “right answer”—the idea is to answer based on your “gut” response so that you are matched with a job for which you are best suited. As you can tell, it would be impossible to offer practice questions or flashcards for this section since there are no right or wrong answers. We do hope this study guide helps you become more comfortable with the type of questions you’ll see, however.

Work Your Register

The key to success in this section of the Postal Service Exam™ is to be sure you are using the fewest number of coins and bills to make a given amount of change. You don’t even have to figure out how much change is needed—that is given to you in the question. Read through this study guide carefully and we think you will be very well prepared to tackle these questions. If you do so quickly, it may improve your score for the section. Also, check out our free practice questions and flashcards so you’ll be really comfortable and confident on test day.


We really hope that our study guides have given a thorough explanation of each test and the parts included in it. You should be more comfortable with your planned approach to whichever Postal Service exam you need to take for the position for which you are applying. Be sure to come back later and review for any additional Post Office exams. We have you covered!
