A-Level Maths Marks per Grade: 2025 Thresholds

Results day can turn one small number into a very large feeling. The useful answer is simple: A-level maths marks per grade are not fixed in advance. Your exam board sets raw mark grade thresholds after each exam series, accounting for the difficulty of that year's papers. The table below gives the confirmed June 2025 boundaries for Edexcel, AQA, OCR Mathematics A and OCR Mathematics B (MEI).

If you are currently preparing for GCSE Maths and considering A Level, these figures also show something important: you do not need full marks to earn a strong grade. You need consistent marks across the whole qualification.

A-level maths raw marks at a glance

Before reading the table, check three details:

• your exam board and specification;
• the correct exam series, such as June 2025;
• the overall qualification boundary, rather than a boundary for one paper.

Each number is the minimum overall mark needed for that grade. For example, the June 2025 Edexcel A* threshold was $258$ out of $300$. A total of $257$ therefore fell within the A grade range.

You can explore earlier series on the Maths Genie Edexcel A Level Maths grade boundaries page and compare OCR years using the OCR A Level grade boundaries archive.

What does a raw mark mean?

A raw mark is the mark awarded for what you wrote in the examination. If a question is worth $5$ marks and the mark scheme awards you $3$, your raw mark is $3$.

For specifications with three equally weighted papers worth $100$ marks each, the overall total is:

$$overall\; raw\; mark=Paper\; 1+Paper\; 2+Paper\; 3.$$

It is the overall qualification total that determines your final grade. Notional paper boundaries may help you judge performance, but you do not receive a separate qualification grade for each paper. A weaker mechanics paper can therefore be balanced by stronger pure maths or statistics marks.

For Edexcel, the A Level Maths predicted grade calculator lets you enter paper marks and compare the total with boundaries from previous series.

Why do A-level maths grade thresholds change?

Grade boundaries move because papers are not identical in difficulty. Examiners use evidence from the completed series when setting the final thresholds. A more demanding paper may lead to lower boundaries; a more accessible paper may produce higher ones.

That is why the 2025 table should explain the 2025 results, not predict an exact future requirement. Before results day, any proposed threshold is only an estimate. Confirmed boundaries are normally released with results information for that series.

This also explains why comparing raw marks across exam boards can be misleading. OCR MEI has a maximum of $275$ marks, while the other qualifications shown have $300$. Different papers and specifications require their own boundaries.

How to use boundaries in your revision

A boundary is most valuable when it becomes a planning tool rather than a source of anxiety. Complete a full paper under timed conditions, mark it carefully, total the raw marks and record where marks disappeared.

The Edexcel A Level Maths revision hub brings together revision lessons, topic questions, worksheets, mini tests and exam resources. You can then use Edexcel A Level Maths past papers with mark schemes and available worked solutions to measure progress.

Aim above a historical boundary rather than treating it as a precise target. Boundaries can rise, and timed performance naturally varies. A sensible margin gives you room for an unfamiliar question or a small arithmetic error.

Common mistakes when checking marks per grade

Using the wrong examination year

June 2024 and June 2025 boundaries are different. Always match the table to the series printed on the paper or results document.

Adding notional paper grades

Your final grade comes from the aggregated qualification mark. Do not assume three paper-level Bs automatically produce an overall B.

Comparing percentages without checking maximum marks

A raw mark of $226$ means something different out of $275$ than out of $300$. Check both the threshold and total available marks.

Treating old thresholds as a promise

Historical boundaries are useful benchmarks, not guaranteed future cut-offs. Predicted papers and grade calculators support revision, but only the exam board confirms the final threshold.

Turn the number into a next step

A grade boundary tells you where one grade ended in a particular series. It cannot tell you which topic will earn your next mark. That comes from reviewing errors, revisiting a lesson and trying another carefully chosen question.
