A useful resource for students to practice their knowledge and examination technique for future external assessments. This is for the following paper: 4PH1 - 2P This mock is based on our 2022 Predicted Papers. 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 2P 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 1c - Forces, movement, shape and momentum (1.11 – 1.33P) • Topic 3d - Light and sound (including core practical 3.27P) (3.14 – 3.29P) • Topic 5c - Changes of state (including practicals 5.11P and 5.14P) (5.8P – 5.14P) • Topic 6d - Electromagnetic induction (6.15 – 6.20P) • Topic 7c - Fission and fusion (7.17 – 7.26) • Topic 8d - Cosmology (8.13P – 8.18P) 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 upcoming examinations and students should not treat it as such. Please use this as an aid, alongside other methods of revision.
