Features
Timed mocks for each paper.
Each paper has its own mock with the number of questions, time limit and pass mark from the qualification guide. Each mock draws questions from across the topics in its unit and favours questions you have not seen yet. Nothing is marked until you finish, and when time runs out your answers are marked as they stood.
See where you need more practice.
Pass or not yet, your score against the pass mark, and a breakdown by topic. Review every answer afterwards, with the wrong ones on their own if you want them.
Learn mode.
Practise topic by topic. After each answer you see the right one, why it is right, and the learning outcome it was written to. If you think a question is wrong, report it from the question itself.
Weak areas.
Every question you get wrong, and every question you flag, comes back in a drill. It leaves once you answer it right twice in a row.
Readiness per paper.
Your last three mocks for each paper make up its readiness score. A paper you have not attempted yet counts as zero. The home screen shows each paper against its pass mark, your three weakest topics with a button to drill each one, and the days left to your exam.
Flashcards and reminders.
68 cards for key facts covered by the qualification: licensing objectives, drug classes, fire classes and extinguishers, threat levels, powers of arrest and the law on force. A daily study reminder at the time you choose, and one the evening before your exam.

FAQ
Are these the real SIA exam questions?
No. They are original practice questions written to the learning outcomes in the qualification specification. The real papers are not published, and you still need an approved training course and the real exams to get a licence.
Which exams does it cover?
The four multiple-choice papers in the Level 2 Award for Door Supervisors in the Private Security Industry: working in the private security industry, working as a door supervisor, conflict management, and physical intervention skills.
What can I use before paying?
50 sample questions from across all four units, one full mock and 10 flashcards. Your results stay readable whether or not you unlock.
How much does it cost?
£4.99 once in the UK, or the local price shown by Google Play in other countries. There is no subscription.
What does "Ready to book" mean?
It appears when your last three mocks on every paper are at or above that paper's pass mark. It is a measure of your own practice, not a prediction of the real result.
Does it need an internet connection or an account?
No account is needed, and the study features work offline.
Can I move my progress to a new phone?
Yes. Back up your progress to a file from Settings and restore it on the new phone.
Does it cover security guarding or CCTV?
No. This app covers the door supervisor qualification only.
