Pearson Edexcel International GCSE Physics (4PH1) grade boundaries
Papers 1 and 2 (1P/2P, and 1PR/2PR in June) · marks out of 180 (Paper 1 + Paper 2)
In short
In June 2026, 4PH1 Physics candidates needed 134 to 138 out of 180 for grade 9 (about 74% to 77%) and 67 to 72 for grade 4, depending on the paper variant.
Grade boundaries by series
| Series | Papers | Max | 9 | 8 | 7 | 6 | 5 | 4 |
|---|---|---|---|---|---|---|---|---|
| June 2026 | 1P, 2P | 180 | 138 | 121 | 105 | 94 | 83 | 72 |
| June 2026 | 1PR, 2PR | 180 | 134 | 116 | 99 | 88 | 77 | 67 |
| November 2025 | 1P, 2P | 180 | 140 | 125 | 110 | 100 | 90 | 80 |
| June 2025 | 1P, 2P | 180 | 143 | 126 | 110 | 98 | 87 | 76 |
| June 2025 | 1PR, 2PR | 180 | 142 | 124 | 107 | 95 | 84 | 73 |
In June there are two sets of papers: 1P/2P and 1PR/2PR, sat in different regions. They are different papers, so their boundaries differ. Grades 3, 2 and 1 are also in the source documents.
How to read these numbers
Across the 3 series in the table, the grade 9 boundary ranged from 134 to 143 out of 180. Boundaries move from series to series because each set of papers is different: a harder paper has a lower boundary.
The boundary is the minimum total mark for the grade. To see where you stand, add up your marks on a full set of papers from the same syllabus and compare the total with the boundaries for that series and variant.
Do not aim for last year's boundary. Aim for a margin above it: boundaries change with every set of papers. Marks are often lost on units, missing working and misreading the question, so practise those as well as the physics or maths.
