IGCSE Biology
Master cell biology, genetics, ecology, and human physiology with comprehensive practical skills training.
IGCSE Biology provides a thorough understanding of living organisms, from cellular structures to ecosystems. Students explore genetics, evolution, human physiology, and ecology while developing essential practical and investigative skills required for A-Level progression.
Why IGCSE Biology Matters
IGCSE and GCSE grades are usually what sixth forms and IB or A Level programs look at when deciding whether you can take a subject further.
Grades: Cambridge IGCSE A*–G (9–1 in England only); Pearson Edexcel International GCSE and UK GCSE 9–1.
Papers, tiers and coursework differ by board and by subject, so lessons follow your own specification: tell us your board and syllabus code on the intro call.

How lessons approach Biology
Understanding the content, and answering the questions the way the mark scheme rewards.
- Create detailed diagrams for biological processes
- Use mnemonics for classification and systems
- Connect topics to real-world applications
- Practice drawing and labeling biological structures
- Master command word definitions (describe, explain, evaluate)
- Practice data analysis and graph interpretation
- Learn mark scheme patterns for common questions
- Time your extended writing responses
