CCEA GCSE Double Award Science grade boundaries 2025
Everything on this page is from CCEA's Raw to Uniform Mark Boundaries for GCSE Double Award Science, Summer 2025. Double Award is two GCSEs in one: Biology, Chemistry and Physics are each tested in a Unit 1 and a Unit 2, and a seventh practical skills unit is shared. A student at Foundation tier sits Foundation papers throughout, and one at Higher sits Higher.

Turning units into a pair
Add the uniform marks from all seven units and look the total up in the pair table. A Foundation candidate on the grade e raw mark in every unit, 26, 24, 23, 26, 21, 21, 34, earned 27 + 27 + 27 + 34 + 34 + 34 + 60 = 243 uniform marks, an EE at 240. A Higher candidate on the grade c* raw marks, 45, 35, 41, 50, 40, 49, 71, earned 45 + 45 + 45 + 57 + 57 + 57 + 101 = 407, which is a C*C* (402 to 419). The pair bands are narrow, 18 to 30 marks wide, and one more raw mark in the practical unit can be worth a whole step.
How 2025 changed from 2024
| Unit and grade | Summer 2024 | Summer 2025 | Change in last year |
|---|---|---|---|
| B1 Higher, c | 32 | 39 | +7 |
| C1 Foundation, c | 30 | 36 | +6 |
| P1 Foundation, c | 38 | 33 | −5 |
| P1 Higher, c* | 45 | 41 | −4 |
| Practical Foundation, c | 45 | 53 | +8 |
| Practical Higher, c | 45 | 52 | +7 |
| Practical Foundation, g | 3 | 16 | +13 |
The practical Unit 7 changed most. On Foundation the grade g boundary went from 3 to 16 and grade c from 45 to 53; on Higher grade c went from 45 to 52 and grade a from 101 to 110. In Physics Unit 1 the opposite happened: Foundation grade c fell from 38 to 33 and Higher grade c* from 45 to 41. Biology B1 Higher grade c rose from 32 to 39. The A*A* line eased from 545 to 544.
What this means when you revise
- The practical Unit 7 is the largest single unit at 150 uniform marks, so its boundary swings matter most.
- Three sciences, two papers each: spread your revision evenly, because a weak Physics unit pulls the same total as a weak Biology one.
- Know whether you are entered for Double Award or Single Award. Single Award is graded A* to G out of 400.
