Edexcel GCSE Maths Foundation Paper 1 is done. The two calculator papers, on 3 June and 10 June, are what matter now. This post sets out what appeared on Paper 1, what the gaps are, and where Foundation students should be directing their revision time over the next two weeks.
This analysis is based on the Edexcel Foundation specification and the confirmed topics from Paper 1, cross-referenced against historical patterns across previous series. It applies to Edexcel Foundation only. As always, no prediction is a guarantee, but the topics listed below have a strong basis for appearing in Papers 2 or 3.
What came up on Foundation Paper 1
Paper 1 covered a broad spread of the specification. The following areas were assessed as main topics and are therefore less likely to reappear in the same form on Papers 2 or 3:
- Basic number operations and written methods
- Fractions, decimals and percentages including percentage calculations
- Ratio and proportion
- Sequences and nth term
- Solving linear equations
- Straight line graphs, including equation of a line
- Quadratic graphs in the common questions section
- Scatter graphs and correlation
- Basic probability from a table
- Properties of shapes and angles
- Transformations and similar shapes
Topic frequency analysis of the 2026 Foundation Paper 1 shows that Number content was slightly below the six-series average. This means standard form, factors and multiples, and upper and lower bounds are more likely than usual to appear on Papers 2 or 3 to rebalance the spread.
What did not come up on Foundation Paper 1
These are the topics absent from Paper 1 that have a strong history of appearing across the Edexcel Foundation series. This is where the revision focus should go.
Perimeter, area and volume
Paper 1 covered shape properties but not measurement and calculation. Perimeter, area and volume consistently appear in some form across every Edexcel Foundation series. Students should be confident with area and perimeter of standard shapes, volume of cuboids and prisms, and area of circles and circumference. These are calculator-friendly topics and are very likely to appear in Papers 2 or 3.
Pythagoras and trigonometry
Neither appeared on Paper 1. It is very unusual for Edexcel to go through an entire series without testing either of these at Foundation. Pythagoras in straightforward right-angled triangles and basic trigonometry using SOHCAHTOA are both realistic topics for Papers 2 or 3. With a calculator now available, these questions become assessable.
Tree diagrams and frequency trees
These are historically among Edexcel's favourite Foundation probability topics and neither appeared on Paper 1. A tree diagram question, either for independent or dependent events, should be considered a high likelihood for Papers 2 or 3. Frequency trees, where counts are used rather than probabilities, are also a regular fixture. Both require clear working and are well worth practising.
Averages and range from a list or table
No question on mean, median, mode or range appeared on Paper 1. This is a fundamental statistics topic and its absence is notable. Students should be comfortable finding averages from a list of values, from a frequency table, and identifying the modal class from a grouped frequency table. These questions are almost certain to appear.
Standard form
Standard form was absent from Paper 1. Writing numbers in standard form, converting between standard form and ordinary numbers, and calculations involving standard form are all testable and are well suited to a calculator paper. This is a topic where many Foundation students can pick up marks reliably if the method is practised.
Compound interest and percentage multipliers
While simple percentage calculations appeared on Paper 1, compound interest and repeated percentage change did not. These are calculator paper topics and regularly appear at Foundation. The multiplier method, where an increase of 5% uses a multiplier of 1.05 and a decrease uses the complement, is the key skill to have ready.
Venn diagrams and sets
Sets and Venn diagrams were absent from Paper 1. At Foundation, this typically involves reading and completing a two-circle Venn diagram, shading regions, and calculating probabilities from one. This is a topic that many students find manageable once they understand the notation and it is likely to appear in Papers 2 or 3.
Simultaneous equations
Simple linear simultaneous equations were not tested on Paper 1. At Foundation, this is typically limited to equations with like coefficients that can be solved by elimination. It is a topic that many Foundation students find challenging but is regularly examined. Working through a few examples before Paper 2 is time well spent.
Papers 2 and 3 allow a calculator but the marks come from setting up the method correctly. A calculator helps with arithmetic but students still need to know which formula to use, how to structure a multi-step solution and what the answer actually means in context. Method marks matter as much as the final answer.
The priority list for Foundation Papers 2 and 3
Based on what did not appear on Paper 1 and the historical weighting of topics across Edexcel Foundation series, here is how to order the revision time between now and Paper 2.
Highest priority, very likely to appear:
- Perimeter, area and volume: including circles, prisms and composite shapes
- Averages and range: from a list, from a frequency table, modal class
- Tree diagrams: independent and dependent events
- Pythagoras: finding a missing side in a right-angled triangle
- Basic trigonometry: SOHCAHTOA, finding a missing angle or side
- Compound interest: multiplier method and the formula
High priority, likely to appear:
- Standard form: converting, ordering and calculating
- Venn diagrams: completing, shading and probability from
- Frequency trees: reading and completing from given information
- Simultaneous equations: elimination method with like coefficients
- Cumulative frequency: drawing a curve and reading off the median and quartiles
Worth keeping ticking over:
- Ratio: this came up on Paper 1 but appears in different forms across all three papers
- Forming and solving equations in context: a reliable multi-step question type
- Drawing and interpreting real-life graphs: speed-distance-time, conversion graphs
How to use the time between papers
The focus now is not on re-covering everything from Paper 1. The focus is on the gaps above. Work through exam questions on each topic using past paper questions sorted by topic, mark honestly with the mark scheme, and be specific about what went wrong rather than just redoing the question.
For topics like Pythagoras and trigonometry, make sure the basic one-step version is solid before attempting harder variations. Foundation questions in these topics are usually straightforward applications, not multi-step problems. Getting the method right reliably is more valuable than attempting the hardest version.
For probability topics, tree diagrams in particular, the marks go to students who lay out the diagram correctly, label all branches with the right probabilities, and multiply along branches rather than adding. Practising the layout until it is automatic will save time and marks in the exam.
After Paper 2, note which topics from this list did not appear and make those the focus for the three days before Paper 3. The spread across all three papers means there is very little that will not be tested somewhere in the series.
