Edexcel IGCSE Grade Boundaries 2026 (June): Every Main Subject + June 2025 (PDF)

Article 254 · IGCSE

"Edexcel IGCSE grade boundaries 2026" is searched twice a year: in August and January when results come out, and all through the spring by students marking mocks and trying to turn a mark into a grade. Pearson publishes the boundaries as one PDF per series with hundreds of rows, which is accurate and unreadable. This page gives the June 2026 boundaries for the main subjects in one table each, with the June 2025 figures alongside so the movement is visible, what the R papers are, how the boundaries are set, and how to use them with a mock, with a printable table.

Download the Edexcel IGCSE June 2026 grade boundaries table (PDF) (every main subject with the mark for each grade, the R papers, the grade 9 and 4 marks against June 2025, and a mock-mark worksheet; two pages, free).

The figures below are from Pearson's "Grade Boundaries, Edexcel International GCSE (9-1), June 2026" document (and the June 2025 one for the comparison lines), subject (cash-in) level, standard papers unless stated. Boundaries are the minimum mark for the grade.

Mathematics

Subject and tier	Papers	Max	9	8	7	6	5	4	3	2	1
Mathematics A (4MA1) Higher	1H, 2H	200	165	138	111	87	64	41	29
Mathematics A (4MA1) Higher, regional	1HR, 2HR	200	171	145	119	94	69	45	33
Mathematics A (4MA1) Foundation	1F, 2F	200					148	125	90	56	22
Mathematics A (4MA1) Foundation, regional	1FR, 2FR	200					147	125	90	55	21
Mathematics B (4MB1)	01, 02	300	246	209	173	142	112	82	67
Mathematics B (4MB1), regional	01R, 02R	300	262	223	185	154	124	94	79

June 2025, for comparison: Mathematics A Higher 9 at 172, 7 at 117, 4 at 44; Foundation 5 at 150, 4 at 128; Mathematics B 9 at 255, 4 at 74. The June 2026 Higher paper was harder at the top (a 9 needed 165, seven marks fewer) and the Foundation 4 moved from 128 to 125.

Read the Higher row carefully: a grade 4 was 41 of 200, about 20 percent, and a grade 9 was 165, about 83 percent. That is the shape of a Higher tier paper everywhere: it is written to separate 7s, 8s and 9s, so the lower grades sit at low marks. A grade 3 is available on Higher (29) as a safety net; below it is unclassified, which is why a student likely to score under 60 is safer on Foundation, where a 5 is the top grade and needed 148.

Sciences

Subject	Papers	Max	9	8	7	6	5	4	3	2	1
Physics (4PH1)	1P, 2P	180	138	121	105	94	83	72	60	49	38
Chemistry (4CH1)	1C, 2C	180	141	122	103	90	78	66	53	41	29
Biology (4BI1)	1B, 2B	180	142	127	112	97	82	67	55	43	32

The regional papers: Physics 1PR/2PR 9 at 134 and 4 at 67; Chemistry 1CR/2CR 9 at 150 and 4 at 77; Biology 1BR/2BR 9 at 146 and 4 at 80. June 2025: Physics 9 at 143 and 4 at 76; Chemistry 151 and 79; Biology 140 and 65. Chemistry moved most: the June 2026 paper was harder across the range, with the 4 thirteen marks lower.

Science Double Award (4SD0), papers 1B, 1C, 1P, out of 330, gives two grades: 9-9 at 257, 9-8 at 242, 8-8 at 227, 8-7 at 212, 7-7 at 198, 7-6 at 186, 6-6 at 174, 6-5 at 163, 5-5 at 152, 5-4 at 141, 4-4 at 130, 4-3 at 118, 3-3 at 106, 3-2 at 94, 2-2 at 83, 2-1 at 72, 1-1 at 61 (regional papers 258, 242, 226, 211, 196, 185, 175, 165, 155, 145, 135, 122, 109, 97, 85, 73, 61).

What the R papers are

Pearson sets a regional version of most papers so that a paper sat in one time zone is not seen before it is sat in another. The R papers are different questions at the same standard, with their own boundaries, which is why the two rows differ by a few marks. A school's region decides which version its candidates sit; a candidate never chooses, and the grades are equivalent.

How the boundaries are set, and why they move

Boundaries are set after the papers are marked, by senior examiners who look at scripts at the key grades against the previous years' standard, supported by statistics on the cohort. The aim is that a grade 7 in 2025 means the same as a grade 7 in 2024, so if a paper turns out harder, the boundaries drop. That is why the Mathematics A Higher 9 was 172 in June 2025 and 165 in June 2026, and why Chemistry's grade 4 moved from 79 to 66 in a year, and why no one can give you "the" grade 9 percentage for a subject: it is set after the exam, not before. Boundaries for the October to November and January series are published with those results and are usually a few marks lower, because the paper is different and the cohort smaller.

How to use them with a mock

Mark the mock with the real mark scheme (the examiner reports and mark schemes for every past paper are free on Pearson's site), strictly.
Add the paper totals to the subject total (both papers for maths and sciences; the max mark in the tables).
Read the total against the June 2026 row for the same tier and papers, allowing five marks either way; where the June 2025 line differs by more than five, the paper's difficulty moved and either year's boundary is a fair guide.
Within five marks of a boundary: on the line, and the next topic fixed decides it. Ten or more above: secure. Ten below: the grade below.
For Mathematics A, the tier decision: a student scoring under about 60 of 200 on Higher mocks in the spring is safer on Foundation, where the same knowledge scores a 4 or 5 with room to spare.

The printable has the tables with a column for the mock marks.

Questions parents ask

1What were the Edexcel IGCSE maths grade boundaries in June 2025?

Mathematics A (4MA1) Higher, papers 1H and 2H, out of 200: grade 9 at 172, 8 at 144, 7 at 117, 6 at 92, 5 at 68, 4 at 44, 3 at 32. Foundation, papers 1F and 2F, out of 200: grade 5 at 150, 4 at 128, 3 at 94, 2 at 60, 1 at 26. The R papers (1HR/2HR, 1FR/2FR) had slightly different boundaries: Higher 9 at 167 and 4 at 41; Foundation 5 at 144 and 4 at 122.

2What percentage do you need for a grade 9 in Edexcel IGCSE?

It varies by subject and year. In June 2025 a 9 needed 86% in Mathematics A Higher (172 of 200), 79% in Physics (143 of 180), 84% in Chemistry (151 of 180), 78% in Biology (140 of 180), 75% in English Language A (113 of 150), 80% in English Literature (120 of 150), 88% in Computer Science (140 of 160) and 82% in History (98 of 120). The boundaries are set after each series so that the standard stays the same from year to year, so the percentage moves with the paper's difficulty.

3What are the R papers in Edexcel IGCSE grade boundaries?

Regional versions of the same paper, sat in a different time zone (so that a paper taken in Asia is not seen before it is sat in Europe), with their own boundaries set to the same standard. A candidate sits either the standard or the R version, decided by the school's region, and the grades are equivalent.

4When are the Edexcel IGCSE grade boundaries published?

On results day for each series: for the May to June series, in August (International GCSE results are usually released a day or two before the UK GCSE results day); for the October to November series, in January; for the January series, in March. Pearson publishes one PDF per series with every subject and paper combination.

5How do I predict my IGCSE grade from a mock?

Mark the mock with the real mark scheme, add the paper totals, and read the mark against the previous June's boundaries for the same tier and papers, allowing five marks either way, because boundaries move a few marks a year. A mark within five of a boundary is on the line; a mark ten above is secure. The printable has the June 2025 table and a space to write the mock marks against it.
