Chemistry 9CH0 and 8CH0, June 2026
From Pearson's June 2026 GCE document, with each line as a share of the total beneath it for the A level.
| A level, June 2026 | A* | A | B | C | D | E |
|---|---|---|---|---|---|---|
| Mark out of 300 | 246 | 212 | 176 | 140 | 104 | 68 |
| Share of the total | 82% | 71% | 59% | 47% | 35% | 23% |
| AS, June 2026 | A | B | C | D | E |
|---|---|---|---|---|---|
| Mark out of 160 | 121 | 104 | 88 | 72 | 56 |
| Share of the total | 76% | 65% | 55% | 45% | 35% |
The course is in the Edexcel A-level Chemistry guide. Other subjects are in Edexcel A-level grade boundaries 2026.
Where 2026 sits
| A level, out of 300 | A* | A | B | C | D | E |
|---|---|---|---|---|---|---|
| June 2024 | 252 | 216 | 177 | 138 | 99 | 61 |
| June 2025 | 246 | 207 | 170 | 133 | 96 | 60 |
| June 2026 | 246 | 212 | 176 | 140 | 104 | 68 |
After the fall in 2025, the A* line held at 246, and the lower lines recovered part of the ground: A* 0, A +5, B +6, C +7, D +8, E +8 on 2025. The A and B lines are still below 2024, when A was 216 and B was 177, while C, D and E are now above it.
The AS jump
AS Chemistry was different. Between 2025 and 2026 the grade A line rose from 106 to 121 out of 160, grade C from 78 to 88 and grade E from 51 to 56. That is 15 marks at A, about 9% of the total, and a far bigger move than any A level line. A student working to the 2025 AS table would have been well off in 2026.
| AS, out of 160 | A | B | C | D | E |
|---|---|---|---|---|---|
| June 2024 | 105 | 91 | 77 | 63 | 49 |
| June 2025 | 106 | 92 | 78 | 64 | 51 |
| June 2026 | 121 | 104 | 88 | 72 | 56 |
A 2026 worked example
A student scores 70 on Paper 1, 68 on Paper 2 and 75 on Paper 3, a total of 213 out of 300. The 2026 A line is 212 and the A* line is 246, so 213 is an A, but only 1 mark above the line. In 2025 the A line was 207, so the same total was 6 above it. Losing 2 marks in 2026 would have meant a B.
| Paper | Length | Marks |
|---|---|---|
| Paper 1: Advanced Inorganic and Physical Chemistry (9CH0/01) | 1 hour 45 minutes | 90 |
| Paper 2: Advanced Organic and Physical Chemistry (9CH0/02) | 1 hour 45 minutes | 90 |
| Paper 3: General and Practical Principles in Chemistry (9CH0/03) | 2 hours 30 minutes | 120 |
The gaps between grades
The 2026 steps are 34 from A* to A, 36 from A to B, 36 from B to C, 36 from C to D and 36 from D to E. Compared with 2025, when the A*-to-A step was 39, the top band is 5 marks narrower, which is why holding the A* line at 246 while the A line rose squeezed it.
Using the 2026 table
- An A* needs 82%.
- An A needs 71%, and a B 59%.
- If you are one mark above a line, the next boundary is what to look at, not the one you cleared.
