Advanced Higher Computing Science grade boundaries 2026: unchanged from 2025

Advanced Higher Computing Science grade boundaries 2026

The source is Qualifications Scotland's workbook Grade boundaries 2026 (reference 26GB), released on 4 August 2026. Qualifications Scotland took over from SQA on 1 February 2026. When we checked on 11 November 2026, the course page listed course reports for 2023, 2024 and 2025 only, so the table below rests on the workbook alone.

The score out of 135 is the sum of a question paper and a project, and the project is the larger part. Keep the Advanced Higher Computing Science guide open for the content of each.

Identical to 2025

Nothing moved. Of the seven courses in this group, it is the only one where all five boundaries match the previous year. Qualifications Scotland says that if levels of difficulty are comparable to previous years it maintains similar boundaries, and that is what the table shows. It also means last year's course report shows what these same lines delivered: 25.4% of candidates got an A in 2025.

A candidate on 52 marks

1. A candidate has 52 out of 135 in total.
2. The D boundary is 53, so 52 falls just below it.
3. The result is No Award, one mark short of a D.
4. A candidate on 53 gets a D, and one on 67 gets a C.

This is why every mark in the bottom part of the table matters. With C = 67 and A = 94, B = 67 + ⌊(2 × 27 + 1) ÷ 4⌋ = 80 and D = 67 − ⌈(2 × 27 − 1) ÷ 4⌉ = 53.

Advanced Higher Computing Science boundaries 2022 to 2026

The A line was 94 in 2022, 93 in 2023 and 2024, and 94 again in 2025 and 2026. In 2026 it equals 70% of 135, and the C line 50%.

How the project is marked

The course specification, which is valid from session 2026 to 27, gives the project 80 marks, split by stage:

• analysis of the problem: 10 marks
• design of the solution: 20 marks
• implementation: 30 marks
• testing the solution: 15 marks
• evaluation of the solution: 5 marks

Implementation is the largest block at 30 marks, but design and testing together are worth 35. The specification says the project is open-brief, uses one of four templates, takes no more than 20 hours and is submitted for external marking. From that specification, each project has 10 mandatory functional requirements and candidates must not add their own. The question paper is the remaining 55 marks.

Using a nearby daily paper

There is no Advanced Higher Computing Science daily paper, so try the Higher Computing Science paper, a short timed paper with 8 questions and 25 to 35 marks. Its answers arrive once it is marked. A percentage on it can be set beside 70% for the A line and 50% for the C line, but the project, 60% of the real marks, is not in it.
