# IGCSE Biology (0610) tutoring online > Our IGCSE Biology tutors teach Cambridge 0610 (Core and Extended) and Pearson Edexcel International GCSE Biology 4BI1, from cells and enzymes to physiology, genetics, ecology and biotechnology, with practical-skills preparation. Classes are live online, 1:1 or in small groups, scheduled for students in the Gulf, the UK and Pakistan. Source: https://www.gradeupinternational.com/igcse/biology Last updated: 2026-10-01 Publisher: GradeUp International (https://www.gradeupinternational.com/) Taught by: [Muhammad Usman](https://www.gradeupinternational.com/tutors/muhammad-usman). IGCSE Biology is the foundation for students interested in medicine, dentistry, veterinary science, biomedical science or psychology, and it is widely taught in Gulf international schools. Cambridge 0610 contains twenty-one topics, running from characteristics and classification of living organisms through human physiology and drugs to inheritance, variation, ecosystems and biotechnology. Edexcel 4BI1 groups similar content into five areas, from the variety of living organisms to the use of biological resources. For Cambridge, Extended candidates sit Paper 2 (45-minute multiple choice, 40 marks, 30%), Paper 4 (theory, 1 hour 15 minutes, 80 marks, 50%) and either Paper 5 or Paper 6 for the practical 20%, while Core candidates take Papers 1 and 3 instead. Edexcel 4BI1 has two untiered papers: Paper 1 of 2 hours (110 marks, 61.1%) and Paper 2 of 1 hour 15 minutes (70 marks, 38.9%), which also tests the bold content. Common weak spots include explaining osmosis and water potential precisely, interpreting enzyme and photosynthesis graphs, monohybrid crosses, and linking structure to function in the heart, lungs and kidney. Long-answer questions reward sequenced, step-by-step explanations rather than lists of keywords. IGCSE Biology leads into A Level Biology and IB Biology, where cell biology, genetics and physiology expand significantly, so building exact terminology now pays off later. ## How is IGCSE Biology examined? ### Cambridge IGCSE Biology (0610), Cambridge International Education | Paper | Duration | Marks | Weighting | | --- | --- | --- | --- | | Paper 1: Multiple Choice (Core) | 45 minutes | 40 | 30% | | Paper 2: Multiple Choice (Extended) | 45 minutes | 40 | 30% | | Paper 3: Theory (Core) | 1 hour 15 minutes | 80 | 50% | | Paper 4: Theory (Extended) | 1 hour 15 minutes | 80 | 50% | | Paper 5: Practical Test | 1 hour 15 minutes | 40 | 20% | | Paper 6: Alternative to Practical | 1 hour | 40 | 20% | Syllabus for examination in 2026, 2027 and 2028. Core: grades C to G. Extended: grades A* to G. Examined in the June and November series (and March in India). Official syllabus: https://www.cambridgeinternational.org/programmes-and-qualifications/cambridge-igcse-biology-0610/ ### Pearson Edexcel International GCSE in Biology (4BI1), Pearson Edexcel | Paper | Duration | Marks | Weighting | | --- | --- | --- | --- | | Paper 1 (4BI1/1B) | 2 hours | 110 | 61.1% | | Paper 2 (4BI1/2B) | 1 hour 15 minutes | 70 | 38.9% | Untiered. Examined in the June and November series. Official syllabus: https://qualifications.pearson.com/en/qualifications/edexcel-international-gcses/international-gcse-biology-2017.html ## What topics are in IGCSE Biology? - Characteristics and classification of living organisms: Listing characteristics of life without precise definitions, and misreading dichotomous keys. - Organisation of the organism: Mixing up cell, tissue, organ and organ system examples. - Movement into and out of cells: Describing active transport without mentioning energy from respiration and movement against a gradient. - Biological molecules: Forgetting the chemical elements that make up carbohydrates, fats and proteins. - Enzymes: Explaining temperature effects without kinetic energy and frequency of collisions. - Plant nutrition: Forgetting controls and destarching in leaf-testing experiments. - Human nutrition: Confusing the roles of bile and of the enzymes it works alongside. - Transport in plants: Omitting environmental factors when explaining changes in transpiration rate. - Transport in animals: Explaining double circulation and heart valves vaguely. - Diseases and immunity: Describing vaccination without memory cells and a faster secondary response. - Gas exchange in humans: Listing features of gas-exchange surfaces without explaining how each helps diffusion. - Respiration: Writing incorrect word or symbol equations for aerobic and anaerobic respiration. - Excretion in humans: Mixing up urea formation in the liver with filtration in the kidney. - Coordination and response: Confusing nervous and hormonal responses, and the feedback steps in homeostasis. - Drugs: Giving vague answers on why antibiotics do not work against viruses. - Reproduction: Mixing up the roles of hormones and of the placenta in human reproduction. - Inheritance: Incomplete genetic diagrams and confusing genotype with phenotype. - Variation and selection: Describing natural selection without variation, survival, reproduction and passing on of alleles. - Organisms and their environment: Confusing the carbon and nitrogen cycles and misreading pyramids of biomass. - Human influences on ecosystems: Explaining eutrophication without the full sequence of events. - Biotechnology and genetic modification: Skipping steps when describing how a human gene is inserted into bacteria to make a human protein such as insulin. ## How do you get top marks? - Use precise terms such as 'water potential', 'active site' and 'partially permeable', and avoid everyday phrasing. - Sequence long explanations step by step (cause, process, result) rather than listing keywords. - When a graph is given, quote figures with units, then describe and explain the pattern. - Draw complete genetic diagrams, including gametes, even when the question only asks for a ratio. - For Edexcel, give the bold 'B' statements dedicated revision time, since they are tested on Paper 2. - In practical questions, name controlled variables and say exactly how each would be kept constant. ## Fees 1:1: PKR 2,800 / AED 110 / GBP 22 per 60-minute class. Small group: PKR 9,500 per month. [All currencies](https://www.gradeupinternational.com/pricing). ## Frequently asked questions ### What is the difference between Core and Extended IGCSE Biology? Core IGCSE Biology covers the Core content and leads to grades C to G, while Extended includes extra Supplement content and allows grades A* to G. Core candidates take Papers 1 and 3; Extended candidates take Papers 2 and 4. All candidates also take a practical paper, either Paper 5 or Paper 6. ### How many papers are there in IGCSE Biology 0610? Each Cambridge IGCSE Biology 0610 candidate sits three papers: a 45-minute multiple-choice paper worth 30%, a 1 hour 15 minute theory paper worth 50% and a practical paper worth 20%. Extended candidates take Papers 2 and 4, Core candidates take Papers 1 and 3, and all candidates choose Paper 5 or Paper 6. ### Is IGCSE Biology hard? IGCSE Biology is not mathematically difficult, but it has a lot of content and expects precise language. Students who revise little and often, test themselves and practise data questions usually find it manageable. Genetics, transport systems and extended explanations are where marks are most commonly lost. ### What is Paper 6 in IGCSE Biology? Paper 6 in Cambridge IGCSE Biology 0610 is the Alternative to Practical, a 1-hour written paper worth 40 marks and 20% of the grade. It covers practical skills such as biological drawings, food tests, variables, data processing and planning investigations. Candidates take it instead of Paper 5, the laboratory-based practical test. ### Is IGCSE Biology enough for A Level Biology? Yes, IGCSE Biology at the Extended or untiered level is the normal preparation for A Level Biology and IB Biology. Most sixth forms also expect good grades in IGCSE Chemistry, since A Level Biology uses biochemistry. Students who took Core Biology may need extra preparation before starting A Level. ### How can I get an A* or a 9 in IGCSE Biology? Students who achieve an A* or 9 in IGCSE Biology cover every topic thoroughly, use exact terminology and practise extended answers and data questions under timed conditions. Self-testing works better than rereading notes. Our tutors build revision around each student's weakest topics, but we never promise grades.
