Why use this diagnostic?

It shows you exactly where the gaps are. Questions are grouped by topic, so you can see at a glance which areas a student is secure in and which need another look.

Calm, not scary. It’s written in the same friendly Without Panic style as the teaching packs: big clear text, lots of white space and gentle humour, so struggling or anxious learners can show what they know.

Easy to act on. Use the results to decide what to teach next, then go to the matching Without Panic packs for that topic, or the complete strand bundle.

Works as a baseline at the start of KS3, an end-of-year check, a catch-up screen after missed school, or an intervention starting point.
