A useful resource for students to practice their knowledge and examination technique for future external assessments. The questions found in these papers are completely original and have been designed from scratch. There has been no reuse of previous exam questions. This is for the following papers: 4SD0 - 1B, 1C and 1P For 1B: Our mock paper follows the format of the true Edexcel IGCSE Biology 1B paper closely, with the CORMS and graph question included. 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 2d - Movement of substances into and out of cells (including practical 2.17 (2.15 – 2.17) • Topic 2g - Gas exchange (including practical 2.50) (2.46 – 2.50) • Topic 2h - Transport (2.51 – 2.54, 2.59 – 2.62, 2.65 – 2.69) • Topic 2j - Co-ordination and response (2.80 – 2.94) • Topic 3a - Reproduction (3.1 – 3.9, 3.11 – 3.13) • Topic 3b - Inheritance (3.14 – 3.15, 3.19 – 3.20, 3.22 – 3.34, 3.38 – 3.39) • Topic 5b - Selective breeding (5.10 – 5.11) For 1C: Our mock 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 1a - States of matter (1.1 – 1.4) • Topic 1c - Atomic structure (1.14 – 1.17) • Topic 1e - Chemical formulae, equations and calculations (including practical 1.36) (1.25 – 1.33, 1.36) • Topic 1g - Covalent bonding (1.44 – 1.51) • Topic 2c - Gases in the atmosphere (2.9 – 2.14) • Topic 2h - Chemical tests (2.44 – 2.50) • Topic 3b - Rates of reaction (3.9 – 3.13) • Topic 4b - Crude oil (4.7 – 4.18) • Topic 4c - Alkanes (4.19 – 4.22) For 1P: 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 (including practical 1.5) (1.3 – 1.10) • Topic 2c - Energy and voltage in circuits (2.7 – 2.21) • Topic 3b - Properties of waves (3.2 – 3.9) • Topic 4b - Energy transfers (4.2 – 4.10) • Topic 5b - Density and pressure (5.3 – 5.7) • Topic 7b - Radioactivity (7.2 – 7.15) • Topic 8b - Motion in the universe (8.2 – 8.6) Disclaimer: This document was created by department heads with many years of experience teaching the Pearson Edexcel IGCSE Science course.
