AQA GCSE Maths Paper 3h 2025 Mark Scheme Pdf

Get the official AQA GCSE Mathematics Higher Tier Paper 3 Calculator mark scheme (8300/3H) from the June 2025 series — the final v1.0 examiner-approved document used to award marks across all 80 marks of the exam. This PDF includes full worked answers, method (M), accuracy (A), independent (B), follow-through (ft), and special case (SC) marking guidance for every question.

The mark scheme provides detailed examiner insight into how marks are awarded across the paper. The *glossary on page 3* clearly explains marking codes such as M (method), A (accuracy), B (independent), ft (follow-through), and SC (special case), helping students understand exactly how marks are given. Early questions like the *unit conversion on page 5* show method and accuracy marks leading to answers such as 3.75 kg, while the *geometry matching question on page 5* demonstrates how independent marks are awarded for correct terminology.

Mid-paper questions such as the *scale diagram on page 9* show acceptable answer ranges (e.g. distances between 10.6–11.4 km), and the *statistics problem on page 14* demonstrates how multi-step mean and percentage increase calculations are marked. Higher-mark questions later in the paper, including the *inequalities question on page 24* and the *similar shapes problem on page 26*, show how method marks, follow-through, and accuracy marks combine to reach full solutions.

Use this mark scheme to mark your June 2025 Paper 3 attempts to real examiner standards — covering algebra, trigonometry, geometry, probability, statistics, and advanced problem solving. It clearly shows how marks are awarded step-by-step, helping you understand exactly where students gain or lose marks.
