Every question has exactly one right answer

Each question was made from exact geometry and checked by computer, twice, by two independent methods, before it was printed. A question was used only if both methods found exactly one correct option and the drawing itself settled the answer.

Questions

Who is this book for?

Children aged 9 to 11, especially those preparing for the 11+, where many non-verbal reasoning papers include 3D and spatial questions. The questions are original and are not taken from any test.

How should we use it?

Work through a set of 10, mark it with the quick answer key, then read the explanations for any mistakes. Short, regular sessions work better than long ones.

Can I print the PDF?

Yes. You may print or copy pages for your own family or pupils. Please do not share the file itself.

Is it linked to an exam board or test provider?

No. This book is not affiliated with, or endorsed by, any 11+ test provider or exam board.

What does UNATUM mean?

It comes from the Latin unum tantum, ‘only one’: every question has only one right answer.

Found something that looks wrong?

Every answer was checked twice, but if something looks wrong, please write to [email protected].
