You multiplied the powers instead of adding them when multiplying indices with the same base.
Complete an interactive paper. Discover exactly why you lost marks. Practise with fresh questions until the mistakes are fixed.
For AQA, Edexcel and OCR students currently working at Grades 3–6.
One interactive question beats another feature list. Click through the diagnosis yourself.
Simplify 5² × 5³.
A common wrong answer is already highlighted. Tap below to diagnose it.
You multiplied the powers instead of adding them when multiplying indices with the same base.
Recoverable once the method is repaired and verified on a fresh question.
5² × 5³ = 5²⁺³ = 5⁵. Short explanation, then practise the pattern.
Next: simplify 2⁴ × 2³. Getting this right counts as recovering the mark.
Answer a short diagnostic or interactive paper.
Classify each lost mark by the real reason it went wrong.
Get a short fix and targeted practice for that mistake type.
Prove it on a fresh equivalent question—not just the solution.
Track marks you can now earn and what to practise next.
This is an example for a Grade 4 → 5 student. Numbers are consistent: 19 marks lost, 8 recovered, 11 still in the gap.
Highest priority: Fractions · Most common mistake: Wrong method
We choose the marks most realistically recoverable for where you are now.
Accessible marks, high-frequency foundations, avoiding blank answers, calculator use, units and basic working.
Accuracy, multi-step Foundation questions, tougher algebra and geometry, method marks and question interpretation.
Higher-tier reasoning, problem solving, combining topics, algebraic fluency, exam speed and question selection.
Coaching paths cover AQA, Edexcel and OCR, Foundation and Higher, so practice matches the marks available on your paper.
Mistake types and repair guidance follow human-reviewed coaching rules—not opaque AI guesses about your grade.
A mark counts as recovered when a previously lost question is later answered correctly, or verified on an equivalent question.
We’re opening the mark recovery coach for Grades 3–6 first. No guaranteed-grade language—only evidence of marks you can now earn.
Open the past papers library for free AQA, Edexcel and OCR papers in Biology, Chemistry, Physics, Maths, English and History. Question papers are paired with mark schemes where we have both files.
One you previously lost for a fixable reason—wrong method, misreading, calculation, missing working, units, or missing knowledge—and can earn again once that mistake is repaired and verified.
Interactive questions are marked instantly. When you’re wrong, you classify why. Those mistake types drive the repair session and the equivalent retry.
No. Start with a free 9-question mark check. Fuller interactive papers are available later—the product is recovering lost marks, not finishing every PDF.
AQA, Edexcel and OCR for GCSE Maths.
Yes. Foundation and Higher are both supported.
No. We never guarantee grades. We estimate the mark gap, help you recover lost marks, and track verified fixes. Exam outcomes still depend on the day.
The free mark check and partial recovery report don’t require payment. Create an account to save progress, verify fixes, and share a parent report.
Yes. Students can share a read-only parent report: marks recovered, grade gap, and what to fix next.
