The original and still the best! For a fourth year running, our heads of department have been hard at work to create a series of predicted exams for Summer 2025!

These questions are completely original and have been designed from scratch. There has been no reuse of previous exam questions.

This is for the following papers: 4CH1 - 1C and 4CH1 - 2C.

For 1C:

Our predicted paper follows the format of the true Edexcel IGCSE Chemistry 1C paper closely. It is also the exact duration and mark-count, with questions of increasing difficulty. A mark scheme is also attached.

The paper covers the following specification points:

• Topic 1b - Elements, compounds and mixtures (1.10 - 1.13)
• Topic 1c - Atomic structure (1.14 - 1.17)
• Topic 1d - The periodic table (1.18 - 1.24)
• Topic 1e - Chemical formulae, equations and calculations (1.25 - 1.33)
• Topic 1f - Ionic bonding (1.37 - 1.41)
• Topic 2a - Group 1 (2.1 - 2.3)
• Topic 2d - Reactivity series (2.15 - 2.20)
• Topic 2h - Chemical tests (2.44 – 2.50)
• Topic 3a - Energetics (3.1 - 3.4)
• Topic 3b - Rates of reaction (3.9 - 3.11)
• Topic 4a - Hydrocarbons (4.1 - 4.6)
• Topic 4b - Crude oil (4.7 - 4.12)
• Topic 4c - Alkanes (4.19 - 4.22)
• Topic 4d - Alkenes (4.23 - 4.28)
• Topic 4h - Synthetic polymers (4.44 - 4.47)

For 2C:

Our predicted paper follows the format of the true Edexcel IGCSE Chemistry 2C paper closely. It is also the exact duration and mark-count, with questions of increasing difficulty. A mark scheme is also attached.

The paper covers the following specification points:

• Topic 1a - States of matter (1.5C - 1.7C)
• Topic 1e - Chemical formulae, equations and calculations (1.25 - 1.35C)
• Topic 1i - Electrolysis (1.55C - 1.60C)
• Topic 2e - Extraction and uses of metals (2.22C - 2.27C)
• Topic 2f - Acids, alkalis and titrations (2.28 - 2.33C)
• Topic 2h - Chemical tests (2.44 - 2.48C)
• Topic 3a - Energetics (3.6C - 3.7C)
• Topic 3c - Reversible reactions and equilibria (3.17 - 3.22C)
• Topic 4e - Alcohols (4.29C - 4.33C)
• Topic 4g - Esters (4.38C - 4.42C)
