IGCSE Mathematics Practice Book Overview
This third edition practice book is specifically designed for Edexcel Specification A, giving you targeted preparation for your IGCSE Mathematics exams. It's endorsed by Edexcel, which means it perfectly matches what you'll face in your actual tests.
The book covers every topic you need to master, from basic arithmetic to complex mathematical reasoning. What makes this particularly useful is that it's structured as a practice book rather than just theory - you'll be working through actual problems similar to those on your exams.
Quick Tip: This isn't just another textbook - it's your exam preparation toolkit designed by experienced mathematics educators.
Whether you're struggling with specific topics or looking to push for top grades, this comprehensive resource has practice questions at every level.
Complete Topic Coverage
The book is brilliantly organised into four main sections that mirror your IGCSE syllabus structure. You'll work through Number topics (like decimals, percentages, and standard form), then move into Algebra (covering everything from basic manipulation to calculus).
The Shape, Space and Measures section tackles geometry, transformations, and trigonometry - often the areas students find most challenging. Finally, Handling Data covers statistics and probability, plus there's a dedicated section for advanced problem-solving.
Each topic builds logically on the previous ones, so you can work through systematically or jump to specific areas where you need extra practice. The variety means you'll never get bored with just one type of maths.
Study Smart: Use the contents page to identify your weak spots and focus your revision time where it matters most.
This structured approach means you're not just learning isolated skills - you're building a complete mathematical toolkit.
Quadratic Equations Practice
Quadratic equations are absolutely crucial for your IGCSE - they appear in multiple contexts and connect algebra with real-world problems. This section throws you straight into solving various types, from simple factoring to using the quadratic formula.
You'll tackle everything from basic equations like x² - 4x = 0 to more complex ones requiring 3 significant figures in your answers. The beauty here is the variety - some questions ask you to solve 2x² - 5x - 3 = 0, while others embed quadratics within simultaneous equations or word problems.
The real-world applications are brilliant for understanding why quadratics matter. You'll work with rectangle problems where you need to show that 2x² + 5x - 16 = 0, connecting geometry with algebra naturally.
Exam Success: Always show clear algebraic working - the mark scheme rewards your method even if your final answer isn't perfect.
Completing the square appears too, which is essential for both solving equations and understanding function transformations later.
Advanced Quadratic Applications
This section really pushes your quadratic equation skills by mixing them with other mathematical concepts. You'll solve simultaneous equations where one is linear and the other involves squares .
The geometric applications are particularly engaging - you'll work with squares and triangles where areas must be equal, leading to equations like 2x² - 4x - 7 = 0. These problems show how quadratics pop up everywhere in mathematics.
Completing the square gets special attention here, with questions asking you to express x² - 4x + 1 in the form ² + b. This technique is absolutely vital for advanced topics and shows up repeatedly in A-level mathematics.
Top Tip: When solving simultaneous equations with circles and lines, you'll often get two solutions - both are usually valid unless the context suggests otherwise.
The mark allocations (ranging from 2 to 7 marks) show you exactly how much detail examiners expect in your working.
Geometric Construction Skills
Construction questions test your practical mathematical skills using only ruler and compasses - no measuring allowed! You'll construct everything from rhombuses with 4.6 cm sides to complex parallelograms using given measurements.
The key constructions you'll master include angle bisectors and perpendicular bisectors. For triangle ABC with sides 6.1 cm, 6.9 cm, and 5.4 cm, you'll construct the triangle accurately then add the angle bisector of angle BAC.
Scale drawings bring real-world applications into your maths. You'll work with scenarios like a 4.8m ladder against a wall, using scales like 1:50 to find distances and angles practically.
Construction Success: Always leave your construction lines visible - they're part of the marks and show your mathematical thinking process.
These skills connect beautifully with trigonometry and Pythagoras' theorem, giving you multiple ways to solve the same problems.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
