Pick your course, board and tier, answer a question, and get the working marked line by line. No account needed to start — make one free when you want your progress to stick.
Free for pupils. No card, no email to try it.
Solve 3(2x − 4) = 5x + 1
You moved 5x across correctly but subtracted 12 instead of adding it. Try x = 13.
Separate question banks, separate mark schemes. Not one GCSE bank relabelled for everyone else.
Grades 1–9 across both tiers, with the interactive answer types the calculator papers ask for.
Pearson International and Cambridge banks written to their own specs — including Core and Extended.
The Level 2 stretch course: calculus, trig identities, vectors and kinematics, marked the same way.
Every board words a question its own way and rewards different working. Switch the course above and this changes with it — these are the boards you can practise today.
Work out the value of x. Give your answer to 1 decimal place. You must show your working.
Solve the equation. Show clear algebraic working. (Total for Question 4 is 3 marks.)
Find x, showing each step of your rearrangement clearly. [3]
Pupils type each line. The engine awards method marks and names the error — not a red cross.
Content follows each spec's real Foundation/Higher, Core/Extended and Level 2 split — shared where the syllabus overlaps, genuinely harder where it doesn't.
Plot points, shade an inequality, sketch a gradient, construct a locus — all instantly marked.
Every question opens into the full method, written the way that board's mark scheme wants it.
Course, board, tier, go. Sign up any time to start keeping a record of your progress.
Every question is authored against the board's actual specification and mark scheme — not a generic approximation.
One flat £100 a year school fee covers GCSE, IGCSE and Additional Maths. Set a class up with a join code, assign by topic and grade band, and get back a report of which errors are actually spreading through the room.
GCSE Maths for AQA, Pearson, and OCR; International GCSE Maths for Pearson (4MA1) and Cambridge (0580 and 0980); and Additional Maths for Cambridge (0606) — all on one platform, one licence for teachers.
No — pick your course, board, and tier and start practising as a guest straight away. Guest progress isn't saved between visits, so create a free account whenever you want that to start being tracked.
You type your working and final answer into one box, the same way you'd write on paper. The marking engine checks for evidence of each real mark-scheme criterion and awards partial credit accordingly — it isn't just right or wrong.
Where a wrong answer matches a known pattern, the feedback names the actual mistake — a sign error, the wrong formula, a rounding slip — instead of just marking it incorrect, and a full worked solution is always available.
Yes — plotting points, shading a region, sketching a gradient, and constructing a locus are all real interactive answer types, instantly marked the same way as typed working.
No — not affiliated with or endorsed by any exam board. Every question is written against each board's real specification and mark scheme, independently.
Yes — online tuition from a qualified teacher with 14+ years' experience, covering GCSE, IGCSE, and Additional Maths, £45/hour. See the tuition page for details.
One account, all three courses. Progress by topic, and a running record of the misconceptions you keep triggering. Free for every pupil.
