CCEA GCSE grade boundaries 2025: the marks for every grade

CCEA GCSE grade boundaries 2025 by subject

The CCEA grade boundaries page now lists its all-subjects table for 2026 only, so this table is built from the A* line in each subject's Raw to Uniform Mark Boundaries document for the Summer 2025 series. Those documents are linked at the foot of the page. The grades A to G are the fixed ones every subject uses, scaled to the subject's total. Digital Technology is out of 300 and Further Maths out of 200.

Double Award Science: the paired grades

A student of Double Award Science receives two grades, from A*A* down to GG, out of a total of 600. We use this qualification as our Combined Science equivalent. Here is the 2025 table next to 2024:

Reading the 2025 series against 2024

A subject total that stays fixed hides a lot of raw mark movement underneath. Each unit has its own raw boundaries, set again in each series, and in 2025 they moved in both directions. Looking at grade c (the boundary behind a subject grade C) across the 41 unit and tier combinations in Maths, Biology, Chemistry, Physics, Double Award Science and Digital Technology (Programming), 21 rose from 2024, 14 fell and 6 stayed the same.

The two Chemistry practical lines dropped by six marks. The Biology Unit 2 and Physics Unit 1 Higher lines rose by five. These are one series' changes, not a trend, and the next series reversed some of them: Physics Unit 1 Foundation was 34 in 2025 and 41 in 2026.

The A* line in 2025

Single Award Science had the largest A* change, up seven to 367. Digital Technology (Programming) moved down five, to 272. Maths, Biology and Physics stayed within one mark.

How a uniform total becomes a grade

For each unit, CCEA gives a raw boundary and a fixed uniform mark for each grade. Your raw mark converts to a uniform mark, the uniform marks from all your units are added, and the total is read against the table. Take Maths: a student on the Higher route sitting M3 and M7 with raw marks of exactly 35 and 42, the grade c boundaries in 2025, would earn 108 and 132 uniform marks. That is a total of 240, a C. A raw mark one below the boundary earns fewer uniform marks, so the grade is not guaranteed by a mark close to the line.

CCEA warns that raw boundaries "change each series" and should be used with caution when estimating future grades. The uniform ones for A to G are stable for the life of the specification.

How much room is above the A*

A* at 394 of 400 in Maths leaves a six mark gap to the maximum, so an A* candidate needs nearly full uniform marks. The Chemistry line of 371 leaves 29 marks of headroom and the Biology line of 355 leaves 45.

If you are revising now

• Aim at the next boundary up, not the one you want, because a harder paper moves the raw line.
• Practise with both calculator and non-calculator Maths papers, since Completion Tests (M5 to M8) use both.
• In the sciences, do not skip the practical unit. Unit 3 is worth 25% of Physics, Chemistry and Biology.

Use today's paper as a gauge

Our daily UK papers are short timed papers of 8 questions and 25 to 35 marks, written for Uni-Sine and not by CCEA. Use one as a check on a topic. Mark it, convert to a percentage and compare with the share each boundary represents, for instance 60% for a C. It will not tell you a grade. It will tell you which topic to revisit.
