- Version 2026-08-11.1
GCSE Maths formula guidance
What changed: Corrected the cone and sphere guidance: these formulae are provided in the question when needed, rather than printed on the Edexcel 1MA1 formula sheet.
Why: The previous wording overstated what appears on the official formula sheet.
- Version 2026-08-11.2
A-level Maths course counts
What changed: Replaced an unexplained 167-point total with the qualification breakdown: 89 Edexcel 9MA0 points plus 78 Edexcel 9FM0 points.
Why: A bare total could be mistaken for one complete course and could drift away from the registered content.
- Version 2026-08-11.3
Grade-boundary guidance
What changed: Removed the claim that grade boundaries follow a fixed 8–12 mark gap.
Why: Boundary gaps vary by course and series, so a fixed range was not supportable.
