Questions

Before you start

How does the 3-step journey work?

Step 1 is a free diagnostic that shows where your child stands. Step 2 is the comprehensive assessment, normally $20 — 100% off (free) when you leave 60 seconds of feedback after your free diagnostic. Step 3 is the exam packs, built from the diagnostic patterns we see in Steps 1 and 2.

Why is the Comprehensive Assessment free?

It isn't automatic — you earn it by completing our feedback form after your free diagnostic. Your feedback directly shapes the mock papers we build, so we genuinely value the trade.

What's in the exam packs, and why does timing matter?

Each pack bundles full-length mock papers for a fixed access period. Year 6 families preparing for selective entry exams sat in 2027 get months of structured mock practice rather than a last-minute scramble.

Do I need a credit card to start?

No — the diagnostic assessment is completely free, with no credit card and no email wall to see your first result.
