You can access Blackstone's Police Investigators' Q&A wherever you have an internet connection. Our site is fully compatible with iOS and Android systems.

Blackstone's Police Investigators’ Q&A
  • Use the Q&As to highlight areas of weakness in your knowledge — target your revision  
  • Don't use the Q&As to revise — study a section of the Manual and then do a test  
  • Use the tests to consolidate all your hard work — study a section, do 4 or 5 Q&As, then go back to the Manual to look over any errors  
  • Don't use the Mock Exam to test yourself — do a maximum of 3 Mock Exams  
  • Remember to read the lead-in question carefully — don't answer the question you think you've been asked  


How many questions are there for each topic?

The number of questions for each topic varies greatly as some areas, such as Burglary or PACE Code C, lend themselves to greater numbers of questions than, say, Blackmail or Kidnap.

When was the last update to the site?

The Q&A site is updated to the new syllabus at the end of the last exam each year (for 2015, this is on 25th November 2015). The site is also updated with new questions throughout the year, with about 30 questions added per month.

How can I ensure I have answered all the questions in the topic and not repeat questions I have already answered?

There are no provisions in the online system for completely preventing repeated questions. This is due to the varied number of questions per subject area, but also because the Q&As should not be used as the only method of revision. The Q&As are there to test you and prepare your exam technique — for this reason, the Q&A authors recommend using the Mock Exam facility a maximum of three times, and for the Test facility to only use the options for 5 or 10 questions at a time. This also prevents users from running out of questions, as the databank holds a finite amount.

How do I subscribe to the Q&A?

You can find out how to subscribe here.

Which online subscription is the best for me?

As there is a short period when two NIE syllabuses are available, we strongly recommend candidates who wish to subscribe to the online Q&A purchase a subscription with the year of their exam in it. For example, if you are taking an exam in 2015, then you should purchase a subscription with 2015 in the title.

What happens after the last 2015 exam?

The final 2015 exam is on 24th November 2015. After this date, the 2015 Manual and Workbook will no longer be available and the Q&A will update to the 2016 syllabus. All subscribers will automatically be upgraded to the new edition if their subscription period runs past the date of the final exam of the current edition. This is the same for both Manual and Workbook subscribers and those using the Q&A.

I have a 2015 subscription but there is still time left after the final exam. What happens to my subscription?

All subscribers will automatically be upgraded to the new edition if their subscription period runs past the date of the final exam of the current edition (the final 2015 exam is on 24th November 2015). This is the same for both Manual and Workbook subscribers and those using the Q&A.

I am taking an exam in 2016. When can I purchase a subscription?

The online Q&A will remain on the 2015 syllabus until after the final 2015 exam (on 24th November), but will update for 2016 questions from 25th November. For this reason, Q&A and Combined (Manual, Workbook, and Q&A) subscribers are strongly advised to wait until 25th November to purchase their subscriptions.

Your browser cache is a temporary storage area that holds web pages that you have looked at. Getting information from the cache is usually quicker for the browser than getting it from the internet.

If you are finding that the website is behaving strangely, you might find that the problem is fixed by clearing (or emptying) your cache.
