Preparing for the Test 

You will increase your chances of obtaining your best possible score if you spend 

a fair amount of time preparing for the test. This includes finding out as much as 

possible about the test ahead of time, paying proper attention to your physical 

well-being before the test, taking care to avoid becoming overly anxious about 

the test and using a good test-taking strategy. Preparation in these areas can 

help you achieve your best possible score on the test. 

For optimal test results, read this study guide thoroughly and answer the sample 

test items beginning on page 7. Make sure you read all the directions carefully 

and each test question completely before answering. 

Test Format 

The POST is made up of three separately-timed test sections. The three sections 

(Mathematics, Reading Comprehension and Grammar) utilize multiple-choice 

and true/false formats. 

Though most of the questions in this test battery relate to police duty, no prior 

knowledge of law or law enforcement will be needed to answer the questions. 

Examination Hints 

Attempt to answer every question on the test. There is no penalty for guessing 

because your score is based on the total number of correct answers. This means 

you should respond to every question, even when you are not certain of the 

correct answer. When you are uncertain, your answer should be your best guess, 

and you should then move on to the next question. You will need to balance the 

amount of time you spend on each question with the total amount of time allotted 

to take the test. If you have extra time before the end of each test section, you 

are allowed to check your work in that section of the test only. 

Time Limits 

It is important to know the amount of time allowed for each section so you can 

pace yourself and not spend too much time on questions causing you problems. 

Remember there is no penalty for guessing. If you find you are spending too 

much time on a question, you should make your best guess and move on. If you 

finish before the time limit for that section expires, you can go back and check 

your answers in the section you are working on. The number of test items and 

time limits for each of the sections of the test are listed below.

Section Test Number of Items Test Time 

I Mathematics 20 45 minutes 

II Reading Comprehension 25 25 minutes 

III Grammar 20 15 minutes 

Marking Your Answers 

You will be taking this test online. It is important to follow the instructions below to 

ensure your answers are recorded accurately. 

 Make sure to click on the oval next to the answer you are selecting. 

 Be sure that you click on only one oval for each question. If you click on more 

than one oval, it will be counted as incorrect, even if one of the answers is 

correct. 

 The three sections of the test are in a multiple-choice format. The ovals 

appear next to the test questions as shown in the example below: 

1. A

B

C

D

E

Notice that for each number there are five ovals labeled A, B, C, D and E. You 

will click on the oval that corresponds to the answer you think is correct. For 

example, assume that for test question number 1, you feel that B is the correct 

answer. You would click on the oval labeled B on your screen as shown in the 

example below. 

1. A

C

D

E

Taking the Test 

This part of the POST study guide provides some common sense advice for the 

day you take the test. Although these points may seem obvious, it is attention to 

details such as these that will increase your probability of obtaining your 

maximum potential score. 

Before The Test Begins 

You will be given instructions for logging in to take the test. Only candidates 

using a desktop or laptop computer with a functioning video camera and 

audio capability will be permitted to take the test (using a tablet or smaller 

device is not allowed for test taking). 

Candidates must have their identification with them at the time of testing. 

Testing will be conducted via video conference. Plan to sign in several minutes 

early in the event any technical issues arise. Confirm that your internet 

connection is strong and reliable. Try to relax but concentrate on the test you are 

about to take. Put outside distractions out of your mind. Give the test you are 

about to take your complete attention. 

Listen Carefully 

The test administrator will provide you with complete and detailed instructions for 

taking the test. Be sure that you pay close attention to what this person has to 

say. Do not read ahead because you may miss something very important. If you 

do not hear or do not understand the directions, ask the test administrator to 

repeat them. It is extremely important that you completely understand the 

directions before the test begins. Once you begin section 1 of the test, you will 

then be on your own so once you complete section 1, and move on to the next 

test sections, ensure you read the instructions carefully before moving on to the 

next test section. 

Test Timing 

Before beginning each section, make a mental note of what time it will be when 

the time limit for the section is up. For example, if the time limit is 15 minutes and 

it is currently 4:15, make a mental note that time will be up at 4:30. This will allow 

you to pace yourself while working through the test. Remember, your score on 

the test will be the total number correct. Therefore, you will want to work both 

quickly and accurately.

You should balance the amount of time you spend on each question. You should 

devote enough time to work through the question, but you should not spend too 

much time on any one question that is giving you difficulty. When this occurs, 

make your best guess and move on to the next question. If you finish before time 

is up, you can always go back and check the questions on which you guessed. 

Preparing Yourself Physically for the Test 

 Avoid junk food and concentrate on a well balanced diet for at least several 

days before the test. 

 Avoid tranquilizers and stimulants, such as coffee, especially on the day of 

the test. 

 Get a good night’s sleep before the test. 

 Do not drink a lot of liquids or eat a big meal before the test. 

 Avoid alcohol several days prior to and especially on the day of the test.

the city center for loading and unloading between 8 and 10 am and 4 to 6 pm

owners within the city center will be issued a “Q” license plate which allows them
