The confusion is understandable. The two qualifications share a lot of mathematics, so a worksheet can look right and still belong to the other route. The fix is a simple habit: decide your route from your entry code, then label every resource against it.
This page shows how to do that with an example you can copy. The code facts themselves are on the 0580 code guide and the 0607 code guide.
Why does this confusion happen?
Online practice, tutorial videos and textbooks are often written for “IGCSE Maths” in general. Titles rarely say which code they serve. A student then revises a topic that is fine for one syllabus, or spends time on a task style that their own syllabus does not use.
There are three common causes:
- The code was never written down. Students remember “Maths” and the tier, but not the four digits on the entry.
- Shared skills hide the difference. Solving a linear equation looks identical on both routes.
- Task style is mistaken for topic. An open investigation or a modelling task is a different kind of question from a short structured one, even when the algebra inside is familiar.
How do I sort a resource in four steps?
- Write down the entry code and exam year at the start of your revision file. Ask your school or exam centre if you are unsure.
- Open the syllabus page for that code on the Cambridge website and keep it beside you. The syllabus navigator helps you record what you found.
- Put each question into one of three boxes: shared skill, check against my syllabus, not my syllabus.
- Re-check the middle box every week, with your teacher if needed, until it is empty.
Worked example: sorting a mixed worksheet
A student finds a worksheet with four questions. Their entry is Mathematics 0580, and they sort them like this.
| Question | What it asks | Box |
|---|---|---|
| Solve 3(x − 2) = 2x + 5 | Linear equation | Shared skill |
| Write 0.000042 in standard form | Number skill | Shared skill |
| Investigate how the number of handshakes grows as people join a room, then state and justify a rule | Open investigation | Check against my syllabus |
| Fit a straight line to a supplied data set and predict a value, stating the assumptions | Modelling task | Check against my syllabus |
Question 1 solved: 3x − 6 = 2x + 5, so x = 11. Check: 3(11 − 2) = 27 and 2(11) + 5 = 27. The skill is safe on either route.
Question 2 solved: move the decimal point five places, so 0.000042 = 4.2 × 10⁻⁵.
Questions 3 and 4: the algebra is familiar, but the task style is what needs checking. The student opens the 0580 syllabus, reads how it describes content and assessment, and notes the answer. If the style is not part of their route, the question goes into “not my syllabus” and is set aside calmly. A student entered for International Mathematics would do the opposite and learn these task types, using the investigations and modelling topics.
A mistake to avoid
The mistaken move: a student entered for 0580 spends a whole week on a modelling worksheet because it was labelled “IGCSE Maths”, and then finds the task style is not part of their own route.
Why it happens: the label described the level, not the code.
The correction: check the syllabus for the topic or task style before starting, and write the code on the worksheet.
The same mistake runs the other way. A student on the International Mathematics route may skip investigation practice because their textbook seemed to skip it. Check, do not assume.
Self-check
Decide which box each item belongs in for your own entry code, then confirm against your syllabus.
1. A worksheet on rearranging formulas.
Show answer
Shared skill. Rearranging formulas is algebra that supports both routes.
2. A worksheet on choosing a viewing window on a graphic display calculator.
Show answer
Check against my syllabus. Calculator expectations are one of the areas the two routes treat differently, so read the calculator statement in your syllabus before spending time here.
3. A question asking for the upper bound of a product of two rounded measurements.
Show answer
Bounds is a measurement skill that both routes are likely to use, but confirm it in the syllabus topic list for your code and year before assuming.
What to do next
Start with the study route guide to build a plan from the correct syllabus, and compare versions with the syllabus version viewer. The route comparison page sets the two side by side.
When a student has mixed material for a long time, gaps build quietly. Our teachers start from your actual entry code in online one-to-one Mathematics tuition, so lessons follow the right syllabus.
