How This Converter Works
This tool takes an exam percentage and maps it to the corresponding UK grade using typical grade boundary thresholds. If you entered raw marks, it first converts them to a percentage, then looks up the grade.
Percentage = (Your Mark / Maximum Mark) x 100
Grade = Boundary Scale lookup(Percentage)
68 / 80 x 100 = 85.0% = GCSE Grade 8 (or A Level Grade A)
About grade boundaries: The thresholds used here (for example, 80% for a Grade 8 or Grade A) are typical approximations widely used across subjects. Actual boundaries are set by AQA, Edexcel, OCR, and WJEC after each exam series and vary by subject and year. Use this converter for a reliable estimate; always check your exam board’s official boundary document after results day.
GCSE Grade Boundaries Reference (9-1)
The 9-1 grading system replaced A*-G in England from 2017. Grade 9 is the highest, reserved for the top students nationally. Here is what each grade represents and its rough percentage threshold.
| Grade | Typical % Threshold | Old Grade | What It Means | UCAS Points |
|---|
| 9 | 90%+ | Above A* | Exceptional, top nationally | N/A (GCSE) |
| 8 | 80-89% | A* | Excellent | N/A |
| 7 | 70-79% | A | Strong pass | N/A |
| 6 | 60-69% | B | Good pass | N/A |
| 5 | 50-59% | High C / low B | Strong standard pass | N/A |
| 4 | 40-49% | C | Standard pass | N/A |
| 3 | 30-39% | D | Below standard | N/A |
| 2 | 20-29% | E | Low | N/A |
| 1 | 10-19% | F / G | Very low | N/A |
| U | Below 10% | U | Ungraded | 0 |
A Level Grade Boundaries Reference (A*-E)
| Grade | Typical % Threshold | UCAS Points | What It Means |
|---|
| A* | 90%+ overall and 90%+ A2 average | 56 | Outstanding, competitive university entry |
| A | 80-89% | 48 | Excellent |
| B | 70-79% | 40 | Good |
| C | 60-69% | 32 | Solid pass |
| D | 50-59% | 24 | Pass |
| E | 40-49% | 16 | Minimum pass |
| U | Below 40% | 0 | Ungraded |
Grade 4 vs Grade 5 at GCSE: Both are passes, but they mean different things. Grade 4 is the “standard pass,” accepted for most jobs, apprenticeships, and further education. Grade 5 is the “strong pass,” and many sixth forms and selective colleges now require at least a Grade 5 in English and Maths. If you are borderline between the two, it is worth knowing which one your next step requires.

| 78% | 7 | A | Strong pass / A grade |
| 72% | 7 | B | Good result |
| 65% | 6 | C | Above average |
| 55% | 5 | D | Standard / strong pass |

Why Your Actual Grade May Differ Slightly
This converter uses fixed percentage thresholds as a guide. In real exams, those thresholds shift each year. Here is how and why that happens.
Paper difficulty
If a paper was harder than usual, the exam board lowers the boundary so that achieving a Grade 6 might only require 57% instead of 60%. In an easier year, the same grade might require 63%. Boundaries move to reflect the difficulty of what was actually on the paper.
Cohort performance
Results are partly standardised against how the national cohort performed. If everyone found a paper hard, boundaries drop to maintain grade consistency year-on-year.
Subject variation
Boundaries differ by subject. A Grade A in Maths might require 76%, while the same grade in History might require 68%. The percentages shown in this converter are general approximations, not subject-specific boundaries.
Where to find exact boundaries: After results day (August), each exam board publishes official grade boundary documents on their websites. AQA at aqa.org.uk, Edexcel at qualifications.pearson.com, OCR at ocr.org.uk, and WJEC at wjec.co.uk. Search “grade boundaries [year] [subject]” to find the specific values.
Frequently Asked Questions
Is 70% a Grade 7 at GCSE?▼
Based on typical grade boundary thresholds, 70% sits right at the Grade 7 threshold. However, the actual boundary for a Grade 7 can vary from around 65% to 75% depending on the subject and the difficulty of that year’s paper. In an unusually hard exam, 70% might be enough for a Grade 8. Always treat the conversion as an estimate.
What is 80% in GCSE and A Level?▼
At GCSE, 80% typically corresponds to a Grade 8, equivalent to the old A* grade. At A Level, 80% is generally the threshold for a Grade A. These are approximate figures based on typical exam board patterns. Exact boundaries are set after each exam series.
What percentage is a pass at GCSE?▼
A “standard pass” at GCSE is Grade 4, which typically requires around 40%. A “strong pass” is Grade 5, typically around 50%. Most schools, employers, and further education providers accept Grade 4 as a pass. Many sixth forms now ask for Grade 5 in English Language and Maths specifically.
What percentage is an A* at A Level?▼
An A* at A Level requires two things: an overall percentage of around 80% (the A grade threshold) AND an average of 90% or above specifically on the A2 components (usually Papers 2 and 3). Getting 90% overall but averaging only 85% on A2 units will typically result in an A, not A*. This converter uses 90% as the A* threshold for a single paper or percentage input, which is an approximation.
Does this converter work for Scottish Highers or Welsh GCSEs?▼
Scottish Highers use a different grading system (A, B, C, D, No Award) with different thresholds, so this converter does not apply directly. Welsh GCSEs awarded by WJEC use the same 9-1 scale as England, so the approximate thresholds in this tool will give a reasonable estimate. Northern Ireland uses both GCSE and A Level systems, so the converter applies there.
Can I use this for a single paper rather than my final grade?▼
Yes. Enter the percentage you scored on any individual paper. Just note that your final grade is based on your total weighted performance across all papers, not just one. A single paper result does not directly determine your final grade unless it is the only component. For a weighted calculation across multiple papers, use the GCSE Grade Calculator or A Level Grade Calculator on this site.
