RAC (Devices) Mock Exam: What It Is, When to Take One and How to Use It
What a RAC (Devices) mock exam is, how the 120 questions map to the four domains, when to take one and how to review it, with a free full-length mock to try.
A mock exam is the closest you can get to exam day without sitting the exam. For the RAC (Devices) credential, a good mock tells you three things: how you cope with the 120-question, 150-minute format, which of the four domains is holding your score back, and whether your pacing holds up under pressure. This page explains what a RAC (Devices) mock exam is, when to take one and how to get the most from it.

What is a RAC (Devices) mock exam?
A mock exam is a full-length, timed practice paper built to mirror the real exam: the same number of questions, the same time limit and a similar mix of topics. It is different from a short topic quiz, which checks one area, and from a practice question bank, which you dip into at your own pace. A mock is a single sitting, taken without interruption, with a score at the end.
The RAC (Devices) exam has 120 multiple-choice questions to be completed in 2.5 hours. A realistic mock therefore has the same shape, and spreads its questions across the four exam domains in line with the published weighting.
The four domains a mock should cover
| Domain | Weight | Questions in a 120-question mock |
|---|---|---|
| I. Strategic Planning | 27% | 32 |
| II. Design and Development | 27% | 32 |
| III. Licensing, Registration and Renewals | 23% | 28 |
| IV. Post-Market Activities | 23% | 28 |
Weightings follow the RAPS content outline and can shift slightly between candidate guides, so always confirm current details with RAPS. If a mock is not weighted like this, its overall score will mislead you.
Why take a full mock rather than only topic questions?
- Stamina. Two and a half hours of focused reading is tiring. Concentration drops late in the paper, and you only find that out by sitting a full one.
- Pacing. Spending too long on a hard question early is the most common way to run short of time. See RAC (Devices) exam time management.
- Mixed domains. On exam day, questions are not grouped by topic. A mock trains you to switch between FDA, EU MDR and global practice from one question to the next.
- An honest baseline. Topic study can feel productive while hiding weak spots. A mock exposes them with a number.
When to take a mock exam
- Early, as a diagnostic. Take one before you start serious study, even if the score is low. It shows where to spend your time.
- Midway, as a checkpoint. After you have covered all four domains once, test whether the learning has stuck.
- Late, as a dress rehearsal. In the final two weeks, sit one under strict exam conditions: no pauses, no notes, no searching.
Leave a gap of several days between mocks so you can review properly. Taking mock after mock without reviewing teaches you very little. For a week-by-week schedule, see the 4-week RAC (Devices) study plan built around mock exams.
How to sit a mock properly
- Choose a quiet two-and-a-half-hour slot and silence your phone.
- Use the timer and do not pause it.
- Do not look anything up. If you do not know, choose the best answer and flag the question.
- Flag questions to revisit, but move on, and use any spare time at the end for review.
What to do after the mock
The score matters less than what you do with it. Spend as long reviewing as you spent sitting the paper: read the explanation for every question you got wrong, and for any you guessed correctly. Then look at results by domain, not just overall. Our guide on how to read your RAC (Devices) mock exam score shows how.
Free mock exam and the next step
Our free mock exam gives you a first benchmark at no cost. When you want more questions to practise on, the 1,000-question RAC (Devices) practice test bank is weighted across the same four domains, and the RAC (Devices) study material page explains how it fits with the Master Handbook. AptSkill MedTech is not affiliated with or endorsed by RAPS, and practice questions are original study material, not actual exam questions.
Frequently asked questions
Is there a free RAC (Devices) mock exam?
Yes. AptSkill MedTech offers a free full-length mock with 120 questions and a 150-minute timer. You enter your email and target exam session, take the paper, and get a domain-wise result with explanations.
How many questions are in a RAC (Devices) mock exam?
A full-length mock has 120 questions, matching the length of the real exam, to be completed in 150 minutes.
Are mock exam questions the same as the real exam?
No. Mock questions are written to match the topics, weighting and question styles of the exam, but they are not real exam questions. Treat the result as an indicative readiness check.
How many mock exams should I take?
Most candidates benefit from two to four, spaced out: one diagnostic early, one or two checkpoints, and a final dress rehearsal. Reviewing each one thoroughly matters more than the total number.
