GCSE CHEMISTRY (9–1): Actual June 2025 PAST PAPER 2: Higher Tier. All Assessment
Questions & Mark Scheme [Edexcel 1CH0/2H]
Exam Resource Summary
The GCSE Chemistry (9–1) June 2025 Paper 2: Higher Tier [Edexcel 1CH0/2H] – All Assessment
Questions & Mark Scheme provides the full official examination paper together with the complete
Edexcel mark scheme. This Higher Tier assessment focuses on the more advanced Paper 2 chemistry
content, including topics such as rates of reaction, reversible reactions and equilibria, organic chemistry,
polymers, chemical tests and analysis, and Earth chemistry (atmosphere, resources, and sustainability).
Each question is paired with clear, structured marking guidance that outlines how marks are awarded for
calculations, multi-step reasoning, and extended responses requiring precise scientific vocabulary. This
makes the resource ideal for focused revision, allowing students to understand examiner expectations
and develop high-scoring exam techniques. It is an essential tool for effective practice and preparation
ahead of the June 2026 Edexcel GCSE Chemistry Paper 2 (Higher Tier) examination.
