Your child talks through hard, unseen 11+ maths problems. We pinpoint where their reasoning breaks down, and tell you exactly what to fix.
The free sample is a preview, not a diagnosis. 3 questions to see the question style, how answering works and what a report looks like.
Full diagnostics from £29. No subscription. See a full example report
Catches misconception of the question, like a skipped “not” or a misread condition.
Reveals how they structure a solution, and what they’re assuming before a number is written.
Shows whether the plan survives to the end, and whether they notice when it doesn’t.
We analyse what your child says, not how they say it. Audio isn’t stored.
What to work on first, and what can wait.
A knowledge gap and a reasoning slip need different fixes. The report tells you which is which.
The level at which your child’s reasoning holds up, from regional grammar to super-selective.
Full transcripts behind every finding.
Take another diagnostic later and the report compares them.
Hand it to your tutor on day one, or use it to steer revision at home.
Your child never sees a score. You decide what to share.
This is about reasoning, not speed.
Pick up where they left off, another day.
Questions created for Cognis11+ and not published anywhere else.
Pay per diagnostic. No subscription.
Spring or summer term of Year 5. Find the habits while there’s plenty of time to fix them.
In the run-up to the exam. Pitched at super-selective, stage 2 and scholarship level.
The run-up, plus a retest 4–6 weeks before the exam to see exactly what’s changed.
Not ready yet? to preview the questions, the answering flow and the report. It’s too short for a diagnosis.
Two London analytics professionals with primary-age children. We built Cognis11+ after a neighbour’s son missed out on his target schools despite leaning heavily on gamified practice apps: plenty of scores, no insight into how he was thinking.
In Year 5, start with the Early Diagnostic. In Year 6, choose Elite, or Elite + Retest to see what’s changed before the exam.
Seeing how Cognis11+ works: the style of questions, how your child answers, and how a report is laid out. Three questions are too few to spot patterns, so treat it as a preview, not a diagnosis.
No. A right answer with little explanation never counts against them. We analyse what they say, not how fluently they say it.
No. Every question is created for Cognis11+ and isn’t published anywhere else.
It uses maths, because the logic is clear-cut. Habits like misreading and not checking tend to show up in other papers too, but we haven’t measured that, so treat them as things to watch for.
How your child copes under time pressure (timed papers do that), or what will happen on the day. It’s a snapshot of how they reason, and a map of what to work on.
