OCR A-level Computer Science grade boundaries 2026: A* to E

OCR A-level Computer Science grade boundaries 2026

The figures come from OCR's June 2026 A Level boundaries PDF. H446 is made of Computer systems, Algorithms and programming and the programming project, with 350 marks in total.

Read across a row to see how little has moved. The A* has run 292, 291, 289, the A 256, 256, 254, and the C 174, 180, 178. The big jump happened at the pass end in 2025, when the E went from 93 to 105, and in 2026 it settled at 104. The 2025 and 2024 figures are from OCR's 2025 and 2024 documents. Our OCR A-level Computer Science guide describes the components and the board-wide 2026 boundaries cover the rest.

Ofqual says senior examiners recommend boundaries after marking and that they vary to reflect the difficulty of each paper. A steady table suggests that the papers were of similar difficulty year on year.

Each component in 2026

Computer systems needed 112 for a notional A*, the same as in 2025. Algorithms and programming needed 114, which is 2 lower than in 2025 (116). At grade C, the second paper moved from 70 to 68. The programming project's boundaries are identical to 2025, at 63 for an A* and 26 for an E, and the upload and postal routes match. These are for information, and the grade is awarded on the total.

AS Computer Science 2026

AS Computer Science rose at every grade in 2026, with the A line going from 102 to 107. There is no A* at AS.

Marks to grade: three 2026 examples

• A grade A. A candidate scores 98 on Computer systems, 100 on Algorithms and programming and 60 on the project, so 258 out of 350. The 2026 boundaries are 254 for an A and 289 for an A*, so the grade is an A, 4 marks above the line and 31 short of an A*.
• A close call at B. A total of 214 is below the B line of 216 by 2, so it is a C. In 2025 the B line was 218, so it would have been a C then too, by 4 marks.
• The pass line. A total of 104 earns an E, because a mark equal to the boundary gets the grade. In 2025 the same total of 104 would have been ungraded, because the E line was 105.

See OCR's guide to A Level grades for the rule.

Using the Computer Science numbers

• Expect stability, but not a guarantee. The boundaries have moved by 2 marks at most in the last year.
• The A* needs 83%. That is almost the same share as in 2024 (83%).
• Finish the project first. Its marks are known before the exams and they count for 70 of the 350.
• Revise both papers equally. Each carries 140 marks, and neither allows a calculator.
