Biology IGCSE Edexcel online classes
Expert online Biology tuition for Pearson Edexcel IGCSE — covering every topic from the 4BI1 syllabus with exam-focused teaching.
How we teach Biology
Edexcel International GCSE Biology (4BI1) is assessed through two written papers and covers the breadth of the subject — cells, molecules and enzymes at one end, ecology, inheritance and disease at the other. Our teaching gives equal weight to understanding the science and writing answers that land the marks.
The course develops from cellular foundations — structure, biological molecules, membrane transport and cell division — into the physiology of whole organisms, then on to genetics, evolution and the immune system. Edexcel rewards candidates who can apply familiar ideas to unfamiliar contexts, so we practise exactly that, alongside the practical and data-analysis skills woven through the specification.
Sessions are live and small-group, with steady feedback that keeps every student moving forward.
