Back by popular demand for a third year! Our heads of department have once again been hard at work to create a series of predicted exams for Summer 2024! This is for the following paper: 4PH1 - 1P These questions are completely original and have been designed from scratch. There has been no reuse of previous exam questions. Our mock paper follows the format of the true Edexcel IGCSE Physics 1P 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 - Movement and position (1.6 - 1.9) • Topic 1c - Forces, movement, shape and momentum (1.13 - 1.24) • Topic 2c - Energy and voltage in circuits (3.2 - 3.9) • Topic 3b - Properties of waves (3.10 - 3.13) • Topic 3d - Light and sound (3.14 - 3.23) • Topic 4b - Energy resources and energy transfers (4.2 - 4.4) • Topic 4c - Work and power (4.14 - 4.17) • Topic 5b - Density and pressure (5.3 - 5.7) • Topic 6c - Electromagnetism (6.8, 6.13 - 6.14) • Topic 7b - Radioactivity (7.2 - 7.16) • Topic 7c - Fission and fusion (7.17 - 7.19) • Topic 8b - Motion in the universe (8.3 - 8.6) Disclaimer: This document was created by department heads with many years of experience teaching the Pearson Edexcel IGCSE Physics course. We cannot however guarantee that it is an accurate representation of the 2024 examinations and students should not treat it as such. Please use this as an aid, alongside other methods of revision.
