Before the first mock exam, your child should have spent several months on topic-based practice tests to build subject knowledge and question-type familiarity. A mock exam is a measurement tool — it works best when there is something meaningful to measure.
Before booking a mock exam, check whether these foundations are in place. Your child does not need to be scoring highly — they need to be familiar enough with the format for the mock to produce useful data.
Your child has worked through all four 11+ subjects with topic-based practice tests
They are scoring above 60% on timed practice tests in most subjects
They are familiar with all the main question types (especially VR and NVR)
They can sit a 45–60 minute timed test without losing focus
You have identified their weaker subjects through practice test data
If most of these are in place, your child is ready for their first mock. If not, spend a few more weeks on practice tests and interactive lessons before introducing mock exams.
Here is a practical 4-mock schedule from Year 5 to exam day.
One full-length mock exam under timed conditions.
Establishes a starting point. Reveals strengths and weaknesses before the main preparation period. Gives the child their first experience of exam-length stamina.
Another full-length mock after 8–10 weeks of focused practice.
Measures improvement since the baseline. Shows whether practice tests between mocks have addressed the weakest areas. Adjusts the revision plan for the summer holidays.
Full mock under strict exam conditions (timed, no breaks beyond what the exam allows, no help).
The summer holidays are when most families intensify preparation. This mock simulates the closest approximation to exam day. It reveals whether the child can sustain focus across multiple papers in a single session.
One final mock exam to peak confidence, followed by light revision only.
The purpose of the final mock is psychological as much as practical. If the score is good, it builds confidence. If there are remaining weak areas, there is still just enough time for targeted practice. After this mock, reduce intensity to avoid burnout.
A mock exam before your child has built foundational knowledge produces an artificially low score and can damage confidence. Always establish subject knowledge with practice tests first, then introduce mocks to measure readiness.
A mock exam every week does not allow enough time between mocks for focused improvement. Each mock should be followed by 3–4 weeks of targeted practice on the weak areas the report highlights. Without this practice gap, mock scores plateau.
If the first mock exam happens in September — the month most real 11+ exams take place — there is no time to act on the results. Starting in spring of Year 5 gives 12+ months to identify weaknesses and address them systematically.
The percentage score is the least useful part of a mock exam report. The topic-level breakdown, time analysis, and question-level review contain the information that drives real improvement. Always spend time reviewing the full report after each mock.
Common questions about mock exam timing and scheduling.
Most families introduce their first mock exam in spring of Year 5 (around March–April), after several months of topic-based practice tests. The first mock establishes a baseline and gives the child their first experience of sitting a full-length exam. Starting earlier than Year 5 is generally not recommended — children benefit more from building subject knowledge first through practice tests.
For most children, yes. Year 4 should focus on building foundational knowledge through topic-based practice tests, reading, and vocabulary development. A full-length timed mock exam at this stage is likely to feel overwhelming and the results will not be meaningful because the child has not yet covered all the 11+ content. Occasionally, an early diagnostic assessment in late Year 4 can be useful if it is positioned as a low-pressure exploration rather than an exam.
A minimum of 3–4 mock exams spread across Year 5 and early Year 6 is recommended. More than 6 total is usually unnecessary and risks fatigue. The key is quality, not quantity — each mock should be followed by a period of focused practice on the weak areas it reveals. Taking mocks every week is counterproductive because it does not allow enough time between mocks for meaningful improvement.
If your child is in Year 6 and has not yet done a mock exam, it is not too late. Start with one mock immediately to establish where they stand. Use the report to target the weakest 2–3 areas with intensive practice for 2–3 weeks, then take a second mock. Even 2 mock exams with focused practice in between will improve exam readiness significantly. The key is using the results actively rather than just collecting scores.
Online mock exams taken at home are practical, cost-effective, and provide instant results with detailed digital reports. They are ideal for most of the preparation period. If possible, consider one in-person mock closer to the exam (at a test centre or school) for the experience of sitting in an unfamiliar room with other children. This can reduce exam-day nerves.
A minimum of 3–4 weeks between mocks is recommended. This allows enough time to work on the weak areas identified in the report through practice tests and then measure improvement on the next mock. Taking mocks only 1 week apart does not allow enough time for the practice-improve-test cycle to work.
Between mocks, focus on targeted practice tests on the specific topics and subjects that the previous mock highlighted as weakest. Review worked solutions for questions that were answered incorrectly. Continue regular reading to build vocabulary. The gap between mocks is where the real learning happens — the mock itself only measures progress.
