IGCSE Maths study strategy

How to revise Cambridge IGCSE Maths (0580) so the facts actually stick — and how to use the tools on this site to get there with short, daily sessions rather than last-minute cramming.

1. Know your papers

Cambridge IGCSE Maths (0580) is taken at one of two tiers, each with two written papers — one non-calculator and one calculator — and no coursework. Core candidates are graded C–G; Extended candidates are graded A*–E. Decide your tier early and match your revision to it: Extended covers everything in Core plus extra content.

Tier	Non-calculator	Calculator
Core (C–G)	Paper 1 · 1h30 · 80 marks	Paper 3 · 1h30 · 100 marks
Extended (A*–E)	Paper 2 · 2h · 100 marks	Paper 4 · 2h · 130 marks

Content is not divided up between the papers — any of the nine strands (Number; Algebra and graphs; Coordinate geometry; Geometry; Mensuration; Trigonometry; Transformations and vectors; Probability; Statistics) can appear on either paper. Extended candidates must also know Extended-only content such as the sine and cosine rules, function notation, and histograms.

2. Read the command words

Marks are lost every year by answering the wrong "type" of question. Train yourself to spot the instruction and give exactly what it asks for:

• Work out / Calculate / Find: show your method — method marks are awarded even if the final answer is wrong.
• Solve: find the value(s) of the unknown; for equations, check whether more than one solution is expected.
• Show that: start from what you are given and reach the stated result, writing every step.
• Prove: a watertight general argument (e.g. algebraic proof), not a single example.
• Give your answer to…: round exactly as told (decimal places, significant figures, or simplest form).
• Estimate: round each number to 1 significant figure first, then calculate.

3. Use active recall, not re-reading

Reading notes feels productive but is one of the weakest ways to revise. Active recall — trying to retrieve an answer from memory before checking — is far more effective, and it is exactly what this site is built around:

• Work through the topic question bank; the system serves you questions you have not mastered first, so you focus on weak spots.
• Drill key terms with the flashcards — recall the definition before flipping the card.
• Read a topic in study notes, then immediately test yourself on it.
• Keep the habit alive with the daily Quizdle.

4. Space it out

Revisit each topic several times with gaps of days, not in one long block. Short daily sessions beat a single marathon: your per-topic scores show what to come back to, and correctly answered questions and flashcards are deliberately set aside so you do not waste time on what you already know.

5. Master the non-calculator skills

One of your two papers has no calculator, so around half of your marks depend on fluent arithmetic and algebra by hand. Drill these until they are automatic: times tables and long multiplication/division, fractions (add, subtract, multiply, divide), percentages without a calculator, standard form, surds and indices, expanding and factorising, solving equations, and exact values (e.g. $\sin 30^{\circ}=\tfrac{1}{2}$). On the calculator papers, learn your calculator: the fraction, power, root, and trig keys, and how to enter standard form correctly.

6. A simple topic-by-topic plan

• Pick one of the nine strands. Read the study notes once.
• Do a 10-question quiz on it; review every wrong answer and its worked solution.
• Drill that topic’s flashcards until you can recall the key methods and terms.
• Come back two or three days later and re-test — aim to push each topic into the green.

7. Common mistakes to avoid

• Not showing your method — method marks are there even when the final answer is wrong.
• Rounding too early — keep full accuracy until the final line, then round as instructed.
• Order of operations (BIDMAS) and dropping negative signs when expanding brackets.
• Misreading the question — wrong units, wrong rounding, or giving area when asked for perimeter.
• Mixing up similar ideas: factor vs multiple, mean vs median, area vs circumference, frequency vs frequency density.
