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: 4BI1 - 2B 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 Biology 2B paper closely. The obligatory comprehension question is also included. A mark scheme is also attached. The paper covers the following specification points: • Topic 2e - Nutrition (2.25 - 2.28) • Topic 2i - Excretion (2.72B - 2.76B) • Topic 2j - Coordination and response (2.83 - 2.92) • Topic 3a - Reproduction (3.3 - 3.7) • Topic 3b - Inheritance (3.16B - 3.18B) • Topic 4c - Cycles within ecosystems (4.11B - 4.15) • Topic 5a - Food production (5.9B) • Topic 5d - Cloning (5.17B - 5.18B) Disclaimer: This document was created by department heads with many years of experience teaching the Pearson Edexcel IGCSE Biology 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.

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! This is for the following paper: 4BI1 - 1B 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 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 1b - Variety of living organisms (1.2 - 1.4) • Topic 2c - Biological molecules (2.7 - 2.11) • Topic 2e - Nutrition (2.18 - 2.20) • Topic 2h - Transport (2.59 - 2.62) • Topic 2j - Co-ordination and response (2.90) • Topic 3a - Reproduction (3.8 - 3.9) • Topic 3b - Inheritance (3.19 - 3.23, 3.38) • Topic 4b - Feeding relationships (4.6) • Topic 4d - Human influences on the environment (4.16) • Topic 5a - Food production (5.2 - 5.4) • Topic 5b - Selective breeding (5.10 - 5.11) • Topic 5c - Genetic modification (5.12 - 5.14) Disclaimer: This document was created by department heads with many years of experience teaching the Pearson Edexcel IGCSE Biology course. We cannot however guarantee that it is an accurate representation of the 2025 examinations and students should not treat it as such. Please use this as an aid, alongside other methods of revision.
