CCEA A-level grade boundaries 2025: grades A to E

Each subject has its own maximum, and the grade lines are fixed fractions of it: 80% for A, 70% for B, 60% for C, 50% for D and 40% for E. CCEA's own explanation says exactly that, and it applies to every subject. The subjects our papers cover use 400 or 600 total uniform marks, so the lines below hold for any series, including this one.

GradeOut of 400: Maths, Further Maths, Digital TechnologyOut of 600: Physics, Chemistry, Biology
A320480
B280420
C240360
D200300
E160240

CCEA gives no A* in this table because an A* is awarded on two conditions, not a line. The candidate needs a grade A overall and 90% or more of the A2 uniform marks. That is 324 of 360 in the 600 mark subjects and 216 of 240 in the others. A* is only given for the whole A-level, never for AS or a single unit.

Raw marks are what moved in 2025

CCEA states that the uniform boundaries do not change over the life of a specification, while the raw boundaries are set again each series. That is where 2025 differed from 2024. Of the 30 units across these six subjects, 15 had a higher raw grade a boundary than in 2024, 14 had a lower one and one stayed the same.

Unit, grade a (raw)Out ofSummer 2024Summer 2025Change
Maths A2 1 (AMT1)15091105+14
Physics A2 1 (APH1)1009079−11
Maths AS 1 (SMT1)1007767−10
Further Maths AS 1 (SFM1)1008778−9

Digital Technology A2 1 (ADT1)1509386−7
Chemistry AS 1 (SCH1)905966+7
Further Maths A2 1 (AFM1)1501101100

Further Maths A2 1 is the one unit that stayed put at 110. Maths A2 1 rose 14 marks, which means that paper was easier to score on, so a candidate needed more raw marks for the same uniform mark. Physics A2 1 fell 11, so 11 fewer raw marks were needed for the same uniform mark. Neither change shows a trend. The 2026 series moved each of them again: Maths A2 1 went from 105 back to 99, and Physics A2 1 rose from 79 to 86.

A worked grade B in Physics

Physics has six units: three at AS and three at A2. If a candidate lands exactly on the grade b boundary in all six units in 2025, the raw marks are 70, 71, 64, 72, 71, 65, which convert to 68, 68, 34, 101, 101, 51 uniform marks. These total 423, the B line of 420. The A2 units add 253 of the 360 available. A grade B candidate cannot reach an A*, and a candidate on grade A who wants an A* still needs 324 across the three A2 units.

Where the whole story is in each subject

The unit tables for every grade are on the subject pages, which copy CCEA's Raw to Uniform Mark Boundaries documents for Summer 2025:

Using the 2025 numbers well

  • Plan on the uniform lines. They do not move, so 80% of the total is an A whatever the series.
  • Treat raw boundaries as one year's evidence. A 14 mark swing in a unit shows how much a single paper can change them.
  • Check the weighting. The AS units count 40% and the A2 units 60%, so a weak AS can be repaired at A2.
  • Know the A* maths. You need to meet two conditions, not one.

Common questions

What were the CCEA A-level grade boundaries in 2025?
The uniform lines were A 320, B 280, C 240, D 200 and E 160 out of 400, and A 480, B 420, C 360, D 300 and E 240 out of 600.
Did the CCEA A-level boundaries change in 2025?
The uniform lines did not. The raw boundaries for individual units changed, by up to 14 marks at grade a.
Where can I find the 2025 unit boundaries?
On CCEA's subject pages, under each subject's Raw to Uniform Mark Boundaries for Summer 2025. Our subject guides copy them.
What does it take to get an A* from CCEA?
A grade A overall, with at least 90% of the A2 uniform marks.
Do AS marks count towards the A-level?
Yes. AS units are 40% and A2 units 60% of the A-level.
