Do Mock Exams Help with the 11 Plus?

Yes, mock exams help. But not in the way most parents think.
The point of a mock is not to predict the result. It is not to rank your child against the field. It is not, despite how it can feel on results day, to confirm whether or not your child is “good enough.”
A mock exam is a diagnostic tool. Used well, it is the single most useful instrument in 11+ preparation. Used badly, it can do real damage. Here is the difference.
What mocks actually do well
1. They expose your child to genuine exam conditions
Sitting in a room of strangers, with a stopwatch on the wall and an invigilator pacing the aisles, is its own skill. Children who have done this five times by exam day are calmer than children doing it for the first time on the morning that counts.
2. They reveal exactly what to work on next
A good mock report tells you not just whether your child got marks, but where they lost them. Was it speed? Specific question types? Careless errors? Reading misinterpretation? Time management? Each of these has a different fix.
3. They build resilience
Most children, taking their first timed paper in formal conditions, will get fewer marks than they expected. That is the point. Better to discover this in February than in September. The second mock is almost always better than the first, simply because they know what is coming.
4. They give parents data
Parents tend to over-worry or under-worry. Mocks reset both. They give you objective data points across a series of months, which is the only honest way to know if progress is being made.
What mocks do badly
1. They predict the actual result poorly
Mock providers vary in difficulty. Some run papers harder than the real exam, some easier. Children typically perform 5 to 15 percentage points better on real exam day, partly because of better fitness, partly because the real paper is genuinely structured to be fairer. So a 75% in a mock could mean an 85% on the day, or it could mean a 70%. Treat the score as a guide, not a verdict.
2. They can damage confidence if mishandled
A score presented as a verdict (“you got 64%, that means you cannot go to QE”) is genuinely harmful. A score presented as data (“64%, let’s see what you can fix before the next one”) is genuinely useful. Same number, completely different effect.
When to start mocks
I would not run a mock before the spring term of Year 5. Earlier than that, the child has not yet covered enough material to make the result meaningful, and the experience is more likely to discourage than to inform.
A reasonable schedule:
- Year 5 spring term: one mock. Frame as practice. Goal: experience, not score.
- Year 5 summer term: two to three mocks, spaced four to six weeks apart.
- Summer holiday: optional one mock at the end, as a temperature check before Year 6.
- Year 6 autumn term: three to five mocks, depending on target schools and exam dates. By this point, mocks become serious data.
Total mocks across Year 5 and Year 6: typically six to eight. More than that risks exam fatigue. Fewer than that risks under exposure.
What makes a mock genuinely useful
Not all mocks are equal. The ones I recommend share four features:
- Realistic conditions. Sat in person, in an unfamiliar room, with proper invigilation and timing. Not at home with a parent watching.
- Properly modelled on the target exam. GL style for grammar school families. ISEB style for independent families. Schools and exam boards differ enough that a generic paper is less useful than a targeted one.
- Honest, detailed feedback. Not just a score, but a breakdown of question types, error patterns, and recommendations.
- Debriefed properly. Either by the mock provider or by you. A score with no debrief is half the value.
How to handle the score conversation
When the result comes back, your child is watching your face. They are deciding, in those first 15 seconds, what kind of conversation this is going to be.
Make it a conversation about curiosity. “What did you find hardest? Which question type cost you marks? What do we want to fix before next time?” Avoid hierarchies. Avoid comparisons to other children. Avoid dramatic relief or dramatic worry, both leak into a child’s sense of how big this all is.
If the score was higher than expected, do not over celebrate. The next mock could equally swing the other way. If the score was lower than expected, do not panic. There is time. There is always time.
What we do at Academic Success
We run mock exams across the year for our Year 5 and Year 6 students, modelled on GL and ISEB formats with separate tracks for the most selective independent schools. Each mock comes with a detailed feedback report and a debrief opportunity, because a mock without proper feedback is half the value.

Frequently asked questions
How many mocks should my child sit?
Across Year 5 and Year 6, typically six to eight. Fewer means under exposure to exam conditions. More risks exam fatigue and diminishing returns.
What if my child does badly in a mock?
Excellent. Now you know exactly what to work on. Sit with them, look at the questions they got wrong, identify patterns, and build a targeted plan for the next four weeks. The mock has just done its job.
What if my child does well in a mock?
Lovely. Do not assume the next one will be the same. Mocks vary, paper difficulty varies, and one good morning is not a guarantee. Use the result as encouragement, not certainty.
Should we sit mocks at multiple providers?
Generally no. Stick with one provider where possible so you can track genuine progress over time. Comparing scores across different providers is not meaningful (their papers vary in difficulty).
What if my child gets very anxious in mocks?
Sit them. Mocks are how you find this out. The fix for exam anxiety is repeated, low stakes exposure to the conditions, with calm support afterwards. Avoiding mocks does not solve anxiety; it just delays the moment it surfaces.
