Popular IGCSE Subjects
IGCSE Physics (0625)
Cambridge IGCSE Physics covers mechanics, thermal physics, waves, electricity, magnetism, and nuclear physics. The exam consists of three papers: Paper 1 (Multiple Choice), Paper 2/4 (Theory), and Paper 3/5/6 (Practical). Extended candidates take Papers 2, 4, and 6, while Core candidates take Papers 1, 3, and 5.
Key topics include: equations of motion, energy transfers, wave properties, circuit calculations, electromagnetic induction, and radioactive decay. Students must be comfortable with mathematical calculations and interpreting graphs.
IGCSE Chemistry (0620)
Cambridge IGCSE Chemistry explores atomic structure, bonding, stoichiometry, electrochemistry, organic chemistry, and chemical analysis. The course develops practical skills through experiments and teaches students to think scientifically about chemical processes in everyday life.
Key topics include: periodic table patterns, ionic and covalent bonding, mole calculations, rates of reaction, reversible reactions, and organic functional groups. Extended candidates also cover electrolysis calculations and equilibrium concepts.
IGCSE Biology (0610)
Cambridge IGCSE Biology is the most content-heavy of the three sciences, covering cell biology, human physiology, plant biology, ecology, genetics, and evolution. Students learn about life processes at molecular, cellular, organ, and ecosystem levels.
Key topics include: cell structure and function, enzymes and nutrition, gas exchange and transport, coordination and response, reproduction, inheritance, and ecosystems. Diagram drawing and labeling are essential skills for this subject.
IGCSE Mathematics (0580)
Cambridge IGCSE Mathematics develops mathematical skills in number, algebra, geometry, statistics, and probability. The course emphasizes problem-solving and mathematical reasoning, preparing students for further study in mathematics, sciences, economics, and engineering.
Key topics include: number operations and percentages, algebraic manipulation and equations, coordinate geometry, trigonometry, probability, and statistical analysis. Extended candidates also cover vectors, matrices, and more complex functions.
IGCSE Computer Science (0478)
Cambridge IGCSE Computer Science teaches computational thinking, programming concepts, and how computer systems work. Students learn to write algorithms, understand data representation, and explore topics like networks, databases, and cybersecurity.
Key topics include: binary and hexadecimal systems, logic gates, CPU architecture, programming constructs (sequence, selection, iteration), arrays, file handling, and database design. Paper 2 requires programming in Python, Visual Basic, or Java.
How to Study for IGCSE Exams
1 Understand the Syllabus
Start by downloading the official Cambridge syllabus for each subject. Highlight the learning objectives and use them as a checklist. Know exactly what examiners can test you on — no surprises on exam day.
2 Use Active Recall
Don't just read notes — test yourself constantly. Use flashcards, practice questions, and past papers. Research shows active recall is 2-3x more effective than passive reading for long-term retention.
3 Practice with Past Papers
Past papers are your best preparation tool. Do them under timed conditions, mark them using the official mark scheme, and identify your weak topics. Aim to complete at least 5 years of papers before your exam.
4 Learn from Mark Schemes
Mark schemes reveal exactly what examiners want. Notice the keywords that earn marks, understand how marks are allocated, and learn the difference between "state" (brief) and "explain" (detailed) questions.
5 Read Examiner Reports
Examiner reports highlight common mistakes and what examiners look for in top answers. Reading these helps you avoid errors that cost marks and understand how to structure high-quality responses.
6 Space Your Revision
Don't cram the night before. Spread your revision over weeks or months using spaced repetition. Review topics multiple times with increasing gaps between sessions for better long-term memory.

Frequently Asked Questions
What is Cambridge IGCSE?
Cambridge IGCSE (International General Certificate of Secondary Education) is the world's most popular international qualification for 14-16 year olds. It is offered by Cambridge Assessment International Education and is recognized by leading universities and employers worldwide as evidence of academic achievement.
How are IGCSE grades calculated?
IGCSE grades range from A* (highest) to G, with A* being the top grade. The grades are determined by your raw marks across all papers, which are then converted using grade thresholds set by Cambridge after each exam session. Grade thresholds vary between sessions based on overall candidate performance.
What is the difference between Core and Extended IGCSE?
Core curriculum covers the essential content and leads to grades C-G. Extended curriculum includes all Core content plus additional topics and leads to grades A*-E. Students aiming for top grades or planning to study A-Level Sciences or Mathematics should take the Extended papers.
When are IGCSE exams held?
Cambridge IGCSE exams are held in three sessions each year: May/June (main session), October/November (second main session), and February/March (available for selected subjects). Check the exam timetable for specific dates.
How many IGCSE subjects should I take?
Most students take 7-10 IGCSE subjects. A typical combination includes English, Mathematics, Sciences (Physics, Chemistry, Biology), a foreign language, and humanities subjects. Universities typically look for 5+ IGCSEs at grade C or above, with competitive universities expecting A*/A grades.
Are IGCSE past papers free to download?
Yes! LumiExams provides free access to Cambridge IGCSE past papers from 2020-2025, including question papers, mark schemes, examiner reports, and grade thresholds. No signup required for viewing or downloading papers.
