IGCSE Biology 0610 — Forms 4–5 Complete Course

Everything you need for IGCSE Biology 0610, in one place. This course follows the 2026–2028 syllabus from the first lesson to exam day. It covers both Core and Extended, so it works whichever paper you are entered for.

You do not need a tutor. Each lesson teaches the idea, shows how it is examined and lets you practise until you are sure.

What is inside

• 46 illustrated lessons in big, clear text with colourful diagrams. Extended-only content is clearly marked.
• Worked examples in every lesson, written one step per line, the way an examiner wants to see it.
• Practice questions with model answers you reveal when you are ready.
• 437 quiz questions — one quiz after every lesson, with every answer explained.
• 5 virtual practicals — osmosis in potato, enzyme rates with catalase, photosynthesis with pondweed, the potometer and respiration in seeds. Take readings, fill in a results table, plot the graph and answer Paper 6 style questions.
• Five full mock sets modelled on the latest papers: Paper 1 and 3 (Core), Paper 2 and 4 (Extended) and Paper 6 (Alternative to Practical). Each paper ends with a marking key that shows how to answer step by step, where the marks go, common mistakes and the lesson to revise.
• Flashcards and a syllabus checklist so you can track what you have mastered.
