For teachers

Build a question set

Tell us what you need covered and how long you have. We build the set, then you work through it and rate every question — the ratings are the point, not a formality.

You

So we can send the set back to you.

What it's for

This changes how the set is built — coverage, weighting, and whether it's fitted to a clock.

How hard

Difficulty here means how close the wrong answers sit to the right one, not how hard the arithmetic is.

Course and lessons

Pick the course, then tick every lesson the set should cover.

How long

We suggest 15 minutes or less. Students never work the answer out here — they read the question, say what is being asked, and choose the first move. That goes quickly, and a short set gets finished properly rather than rushed at the end.

Two different clocks. The first decides how many questions the set gets; the second is what a student actually has on the clock. They do not have to match.

Anything else

Skills you especially want hit, things your class has struggled with, anything to avoid.
