KRISH.one

GCSE maths practice
that goes where you're weakest.

Every topic broken into skills, five fresh questions a day, and real papers under exam conditions. Questions rebuild themselves with new numbers each time, so there's always more to practise.

What you get

Built around the way GCSE maths is actually revised — little and often, aimed at the gaps.

A question never runs out

Every question rebuilds itself with fresh numbers each time it's asked. Answers can't be memorised, and retrying a skill is new practice, not a memory test.

Five questions a day

The same five for every student each day, with your own numbers. Get one wrong and it comes back with fresh numbers until you crack it — finish all five and your streak lives on.

Real exam papers

Full papers under timed conditions. No feedback until you hand in, then a mark out of marks and the right answer against every question.

Live lessons on Zoom

Two hours every weekend, taught live and joined straight from the site, with a countdown so you never miss the start.

Marked, then explained

Every answer is marked the moment you commit to it, the right one is named either way, and the working is spelled out underneath.

Diagrams and proper notation

Circle theorems, transformations and histograms with the figures they need, and fractions that actually look like fractions.

A look inside

The dashboard and the leaderboard, laid out exactly as they are inside. The students and their numbers are invented; nothing else is.

Every module opens into its skills

A module is a row of circles, one per subtopic. Finish every question in one and it fills in and gets a tick. The ∞ circle at the end is overall practice — a mixed bank for the whole module that never runs out.

XP worth competing over

Every question you get right earns XP, and enough XP is a level — the little purple badge on each avatar. There's a table for this week as well as this month, so a good week counts however far behind you started.

I built KRISH.one because I kept teaching the same things over and over, and kept seeing the same gaps. Practice works when it is aimed at what you actually keep getting wrong — not at whatever comes next in the textbook.
