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: 4BI1 - 1B and 4BI1 - 2B. 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 2B: 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 2c Biological molecules (including practical 2.9 and practical 2.14B) (2.7 – 2.14B) • Topic 2g Gas exchange (including practical 2.45B) (2.40B – 2.50) • Topic 2i Excretion (2.70 – 2.79B) • Topic 3b Inheritance (3.14 – 3.39) • Topic 4c Cycles within ecosystems (4.10 – 4.11B) • Topic 4d Human influences on the environment (4.12 – 4.18B) Disclaimer: This document was created by department heads with many years of experience teaching the Pearson Edexcel IGCSE Biology course.
