How to Read Your RAC (Devices) Mock Exam Score and What to Do Next

You have finished a RAC (Devices) mock exam and have a percentage on the screen. What does it actually mean, and what should you do next? This guide explains how to read a mock score sensibly, why the domain breakdown matters more than the headline number, and how to turn the result into a study plan.

If you have not taken one yet, start with the free RAC (Devices) mock exam, then come back to this page with your result.

A mock score is an indicator, not a prediction

RAPS reports a scaled score for the real exam, not a raw percentage, so a mock percentage cannot be converted into an official result. Treat it as a readiness check: it tells you where you stand today against a paper built to the same format and weighting. Mock questions are original practice material and are not real exam questions, which is another reason not to over-read a single number.

Reading the overall percentage

As a rough guide, AptSkill’s free mock uses three bands:

Overall score	Band	What it usually means
70% or more	On track	You are scoring at a level that supports a confident attempt. Keep sharpening your weakest domain.
55% to 69%	Developing	You have the foundations, with clear gaps. Targeted practice should lift the score quickly.
Below 55%	Needs focused prep	Work domain by domain, read every explanation and re-test. Large gains are common in the first few weeks.

A sensible aim before sitting the real exam is sustained scores of 70% or more across all four domains, not just overall. One good result can be luck, so look for a pattern across more than one mock.

Why the domain breakdown matters more

An overall 68% can hide a 85% in one domain and a 48% in another. Because the real exam draws from all four domains, a weak one is a risk you can fix. Look at your result against the exam weighting:

Domain	Weight
I. Strategic Planning	27%
II. Design and Development	27%
III. Licensing, Registration and Renewals	23%
IV. Post-Market Activities	23%

A low score in a 27% domain costs you more than the same score in a 23% domain, so fix the larger domains first when two are equally weak.

Review every wrong answer, and your lucky guesses

Go through the answer review and sort each miss into one of three causes:

• Knowledge gap. You did not know the requirement. Go back to your study material for that topic and re-read it.
• Misread question. You knew the content but missed a word such as “BEST”, “FIRST” or “NOT”. Practise slowing down on question stems. See how to answer RAC exam questions.
• Time pressure. You rushed late in the paper. This is a pacing problem, covered in exam time management.

Also review questions you guessed correctly. A right answer you cannot explain is a weak spot that has not shown up yet.

Look at question types too

RAC (Devices) practice questions fall into Recall, Application and Analysis levels. If you score well on Recall but poorly on Application and Analysis, you know the facts but are not yet applying them to scenarios. The fix is more scenario practice, not more reading.

Turn the result into a plan

1. Rank the four domains from weakest to strongest.
2. Spend roughly half of your next study block on the weakest two.
3. Re-study from your handbook or notes, then answer fresh questions on those topics.
4. Sit another full mock in one to two weeks and compare domain by domain.

For a ready-made schedule, see the 4-week study plan built around mock exams. For more questions to practise on, the RAC (Devices) practice test bank has 1,000 exam-style questions with explanations. AptSkill MedTech is not affiliated with or endorsed by RAPS; confirm exam details with RAPS.

Frequently asked questions

What is a good score on a RAC (Devices) mock exam?

Aim for 70% or more overall, and at or above 70% in each of the four domains, across more than one mock. Because RAPS reports a scaled score, a mock percentage is an indicator, not a guarantee.

Does a mock percentage equal my real exam score?

No. The real exam is reported as a scaled score, so the two cannot be converted directly. Use the mock to track progress and find weak domains.

My score went down on the second mock. Should I worry?

Not necessarily. Different mocks contain different questions, and a single result is noisy. Look at the domain breakdown and the reasons you missed questions before drawing conclusions.

How soon should I retake a mock?

Wait until you have reviewed your errors and restudied the weak domains, usually one to two weeks. Retaking straight away mostly measures your memory of the questions.
