Edexcel IGCSE Chemistry Past Papers with Mark Schemes [PDFs]

The Pearson Edexcel International GCSE in Chemistry (Modular) (4XCH1) will begin first teaching in September 2024, with first examinations in June 2025 and first certification in August 2025. This qualification has a modular structure with two mandatory units that can be taken in any order or re-sat. Each unit is assessed through a 1 hour and 40 minute written examination worth 90 marks, with each unit contributing 50% of the total International GCSE grade. Both exams include multiple-choice questions, short-answer questions, calculations, and extended open-response questions. Calculators are allowed in both examinations. The units are available in both June and November exam series.

The content is organized into eight main topics spread across the two units. Unit 1 covers Principles of Chemistry (Part 1), Inorganic Chemistry (Part 1), Physical Chemistry (Part 1), and Organic Chemistry (Part 1). Unit 2 covers Principles of Chemistry (Part 2), Inorganic Chemistry (Part 2), Physical Chemistry (Part 2), and Organic Chemistry (Part 2). The qualification aims to help students learn about patterns in chemistry, gain knowledge of chemical facts and concepts, develop practical skills, analyze data, and prepare for advanced courses. Students will learn to apply principles to different contexts, evaluate information, and develop problem-solving skills. The modular structure offers flexibility, allowing students to sit exams when they’re ready and providing opportunities to resit individual unit assessments before receiving their final grade.
