How IGCSE Mathematics (0580) is really marked
0580 is examined across Papers 1, 2, 3 and 4, split by tier (Core: Papers 1 and 3; Extended: Papers 2 and 4), each in three variants, totalling 2,598 questions in our bank. Marking is split almost evenly between the calculation style and the points style: 1,170 questions in our bank use the calculation style against 1,428 points-marked, meaning close to half of the syllabus is marked on method as well as final answer.
The Extended-tier papers carry a higher calculation share than the Core papers: Paper 42, for instance, splits 133 calculation questions against 111 points-marked out of 244 questions and 620 marks, while Paper 11 (Core) splits closer to 83 calculation against 102 points out of 185 questions. This means the longer, higher-tariff Extended questions more often require full working to be shown for method marks to be awarded, even where the final answer alone would be worth only one or two of the marks.
The points style in 0580 covers questions like stating a term, drawing an accurate diagram, or completing a table, where each mark is for a specific discrete response rather than for arithmetic. Across both tiers, the balance between showing method and giving a clean final answer is close, so neither working nor accuracy can be neglected.
Command words in IGCSE Mathematics
| Command word | Times in our bank | What it demands |
|---|---|---|
| Find | 1103 | Work out the required value using an appropriate method, showing enough working for method marks to be awarded even if the final answer is not fully simplified. |
| Calculate | 731 | Use a given formula or set of values to work out a numerical answer, showing the substitution and method, with the final answer to an appropriate degree of accuracy. |
| Draw | 233 | Produce an accurate diagram, graph or construction using the equipment and precision expected, such as a ruled line or a curve through plotted points. |
| State | 124 | Give a mathematical fact, term or value directly, without further working or justification. |
| Express | 100 | Write a quantity or relationship in a specified form, such as a fraction, standard form, or in terms of a given variable. |
| Work-out | 76 | Carry out a calculation using given information, similar in demand to Calculate, generally requiring working to be shown. |
| Describe | 57 | Give a clear, accurate account of a transformation, sequence or relationship, using correct mathematical terms. |
| Complete | 42 | Fill in missing entries in a table, diagram or expression so that it is mathematically correct and consistent. |
How to revise with past papers
Because roughly half the marks in 0580 come from method-marked calculation questions, past-paper practice should focus on showing every step clearly, not just producing the final number. Method marks can often be earned even when a later arithmetic slip means the final answer is wrong, so incomplete working throws away marks unnecessarily.
Working through both Core and Extended past papers for the same topic (where available) helps show how the same underlying skill is tested at different levels of demand, and makes clear where the Extended tier expects a fuller chain of working for the same number of final marks.
For the points-marked minority of questions — stating terms, completing tables, drawing accurate diagrams — accuracy and following instructions precisely (correct units, correct form of answer, correct level of accuracy) matter as much as the underlying mathematics, so check the exact form the question asks for before finalising an answer.

Is 0580 mostly method marks or points marks?
It is close to an even split: 1,170 calculation-style questions against 1,428 points-marked questions in our bank, so both showing working and giving precise, correctly formatted answers matter.
Do Extended papers have a different marking balance to Core papers?
Yes, broadly. In our bank the Extended papers (such as Paper 42, with 133 calculation questions against 111 points-marked) carry a higher calculation share than the Core papers (such as Paper 11, with 83 calculation against 102 points-marked).
What's the most common command word in 0580?
Find, appearing 1,103 times in our bank, followed by Calculate at 731.
Do I need to show working even when I can do a calculation in my head?
This is generic advice: showing working protects method marks even if a later step goes wrong, so it is worth doing routinely rather than only when a question feels difficult.
