You know the maths. So where did the marks go?
GCSE & IGCSE MATHS · AQA · EDEXCEL · OCR · CAMBRIDGE
Most GCSE students don't lose marks because they don't know enough. They lose them by misreading the question, showing too little working and running out of time. Maths Forensics finds exactly where your marks disappear, and fixes it before your mocks.
THE EVIDENCE
Nearly 1 in 3 lost marks are on questions the student could already do
From Maths Forensics analysis of 280 anonymised GCSE maths scripts, every lost mark coded by cause.
THE EVIDENCE
Three parts to every mark
You need the maths, the technique to turn it into marks, and the practice to do it under exam conditions. Everything we make fits one of the three.
Know it
Every GCSE topic, practised until it sticks, with the misconceptions that cost the most marks named and fixed.
Every GCSE topic up to grade 9, with feedback that names your mistake
Video lessons on the misconceptions that cost students the most marks
Fast maths games that make practice stick, starting with Hot Pursuit

THE INVESTIGATOR
I've marked thousands of GCSE papers. The same marks go missing every year
I'm Mike Taylor, and I've taught GCSE maths for more than eleven years across AQA, Edexcel and Cambridge IGCSE. Every summer I watch capable students walk out of the exam feeling they did worse than they should have. When the papers come back, I can see exactly why.
It's almost never the maths. It's the reading , the working and the timing. Maths Forensicsis the system I use with my own students to stop that happening .

Frequently Asked Questions
If you lose marks on questions you know how to do, start with the Exam Execution Guide (£47.99), which fixes how you sit the paper. If certain topics keep costing you, the Mark Recovery System (£79.99 until 31 January) includes the whole Guide plus six topic Casefiles. If you need practice across the whole syllabus, the Lab Exam Pass (£49 until 31 January) gives you every topic, up to grade 8–9, with Incident Room games. Want all of it? The Full Investigation brings everything together, with full Forensic Marking, from January.
Write your answer with a stylus, your finger or a mouse, or upload a photo of your working. Forensic Marking marks it against the mark scheme, like an examiner would, and shows every mark you earned or lost, the line where it happened and how to fix it. It launches in January 2027:
Free accounts: 1 marked question a week
Exam Pass: 5 a week
The Full Investigation: 40 a week, plus whole-paper marking
The marking is done by AI, and you can dispute any mark.
The Guide and the Mark Recovery System work for AQA, Edexcel, OCR and Cambridge IGCSE, Foundation or Higher. The Lab covers the GCSE and IGCSE Higher syllabus. Cold Case papers are Higher tier, written in the AQA three-paper style, and suit AQA and Edexcel students.
Until your exams. It's one payment, not a subscription, so there's nothing to cancel.
Use it with your next practice paper. If it doesn't improve your exam approach within 14 days, ask for a refund.
