Want to Score High in IGCSE Math? Focus on These 5 Topics First

Struggling to figure out what to focus on in IGCSE Mathematics? You’re not alone.

Many students feel overwhelmed by the long syllabus and endless past papers. But here’s a secret: Not all math topics carry the same weight. Some appear more frequently, are harder to master, and carry higher marks. These are the “power topics”—the ones that determine your final grade.

In this in-depth guide, we’re doing a subject deep dive into the top 5 IGCSE math topics that have the greatest impact on your performance, whether you're taking the Cambridge 0580, Cambridge 0607, or Edexcel International GCSE.

If you want to study smarter—not harder—this guide is your perfect starting point.

Why Topic Selection Matters in IGCSE Math

‍

Before we dive into the list, let’s answer a basic question:

Isn’t it better to cover everything equally?

Ideally, yes. But realistically? Time is limited.

In exam prep, especially in the final 3–6 months, prioritizing is essential. By focusing first on high-frequency, high-weight, and high-difficulty topics, you:

• Improve your overall accuracy
• Reduce panic in the exam
• Boost your grade by maximizing returns

We’ve analyzed hundreds of past papers, examiner reports, and student feedback to bring you this shortlist of top topics.

1: Algebra – The Backbone of IGCSE Math

Why It Matters:

Algebra is tested in almost every paper, often through multiple question types:

• Simplifying expressions
• Expanding and factorising
• Solving linear and quadratic equations
• Rearranging formulas

For many students, Algebra forms the foundation of other topics like Graphs, Geometry, and Word Problems.

Most Common Algebra Subtopics:

• Solving equations (linear, simultaneous, quadratic)
• Factorising quadratic expressions
• Algebraic fractions
• Using and rearranging formulas
• Solving inequalities

Tips for Mastery:

• Create a formula sheet and memorize the forms for factorization
• Practice step-by-step solving with brackets and signs
• Use algebra tiles or visual aids if you're a visual learner

💡 Mozakrah Insider Tip:

Algebra questions often appear early in Paper 2 and in mid-to-late Paper 4. Prioritize practicing both short-form and structured versions.

2: Number & Percentage Applications – Easy to Learn, Easy to Lose Marks

‍

Why It Matters:

IGCSE loves real-life applications. Questions about profit/loss, interest, percentage increase, and exchange rates appear often—and mistakes are common.

These are often calculator questions, so the issue isn’t math skill, it’s concept clarity.

Hot Subtopics to Focus On:

• Percentages (simple, compound, reverse)
• Currency conversion
• Speed, Distance, Time
• Proportion and Ratio
• Estimation and Bounds

Common Mistakes to Avoid:

• Forgetting units (especially time and currency)
• Rounding too early
• Misreading whether to increase or decrease by percentage

Tips for Mastery:

• Keep a "math vocabulary" sheet for terms like "decrease by 20%" or "increase by a factor of 1.5"
• Practice without a calculator first to strengthen logic

🧠 Mozakrah’s Pro Tip:

Practice word problems with diagrams. Draw what's happening in the question—it makes problems 3x easier to understand.

3: Geometry & Mensuration – Diagrams, Formulas, and Accuracy

Why It Matters:

Geometry and Mensuration questions are formula-heavy and often appear in long-form questions. These problems can earn you 6–8 marks each—but only if you’re accurate.

Topics That Dominate the Papers:

• Angles (parallel lines, polygons, circles)
• Properties of shapes (quadrilaterals, triangles)
• Area and Volume (cylinders, cones, spheres)
• Pythagoras & Trigonometry
• Bearings and Scale Drawings

Tips to Succeed:

• Memorize all key formulas (use flashcards!)
• Always label your diagrams
• Use full calculator accuracy and only round in the final step

📌 Common Pitfall:

Skipping the diagram or not reading it carefully. Many students lose marks by mislabeling angles or using the wrong shape property.

📘 Helpful Resource:

Mozakrah offers downloadable Geometry Cheat Sheets and 3D shape animations to help you visualize problems more clearly.

4: Graphs & Functions – Where Visuals Meet Algebra

‍

Why It Matters:

Graph questions test your understanding of relationships, not just plotting points.

You’ll find these in both Paper 2 (short) and Paper 4 (extended) exams—especially in questions about:

• Linear & Quadratic Graphs
• Real-life graphs (distance-time, speed-time)
• Gradient & Intercept
• Transformations of functions

What You MUST Know:

• How to find gradient (m) and y-intercept (c) from equations
• Sketching vs plotting accurately
• Finding the equation of a line from a graph
• Applying graph transformations (reflections, stretches, translations)

🧠 Tip for Visual Learners:

Use graphing tools like Desmos or GeoGebra to understand how equations transform shapes.

💥 Past Paper Hack:

These are “layered” questions—meaning even if you mess up the graph plot, you can still earn method marks in later parts.

5: Probability & Statistics – Fast Marks If You’re Careful

Why It Matters:

These topics are easy to underestimate. But together, they account for 15–20% of many IGCSE Math papers.

And guess what? Students often rush through them because they look “easy” but end up making avoidable mistakes.

Most Tested Subtopics:

• Probability trees
• Combined probability (AND, OR, NOT)
• Mean, Median, Mode, Range
• Cumulative Frequency Graphs
• Histograms and Pie Charts

Exam Strategy:

• Learn how to explain why an event is more/less likely in 1–2 sentences
• Use a highlighter for frequency tables so you don’t miss rows
• Always check that total probability = 1

✅ Double-Check These:

• Adding up probabilities
• Labeling axes on graphs
• Showing working even if it seems “mental math”

Mozakrah’s Fast Fix:

Use our data handling practice sets that mimic real-life IGCSE exam tables, giving you repetition and confidence.

What About the Rest of the Topics?

Of course, topics like:

• Vectors
• Matrices
• Transformations
• Sets

also appear—but typically in fewer questions or worth fewer marks overall. Focus on them after you’ve mastered the top 5.
