A Level Grade Boundaries Explained | Tutorelli
30 October, 2026
How A-Level grades work
A-Levels are graded from A* to E, with U meaning ungraded. A* is the highest grade.
| A-Level grade. What it generally represents | |
| A* | Exceptional performance |
| A | Strong performance |
| B | Good performance |
| C | Solid performance |
| D | Lower pass |
| E | Minimum pass |
| U | Ungraded |
As with GCSEs, A-Level grade boundaries are the minimum marks needed for each grade. They are set after marking and published on results day.

How exam boards set grade boundaries
Exam boards do not decide grade boundaries before students sit the exam. Once papers have been marked, senior examiners and subject experts review the difficulty of the paper, student work, examiner feedback and statistical evidence.
They then decide the minimum mark needed for each grade.
This process is designed to maintain standards from one year to the next. It means that a student should receive a similar grade for a similar level of performance, regardless of whether their particular paper was slightly harder or easier than the previous year’s.
Do grade boundaries change every year?
Yes. Grade boundaries can change for every exam series. They are not published in advance because exam boards need to see how students have performed on the actual papers. If an exam is more difficult than usual, the boundary for a grade may be lower; if it is easier, the boundary may be higher.
AQA states that grade boundaries are published at 8am on results day.
This is why students should not assume that “70% always equals a Grade 7” or “80% always equals an A.” The exact mark needed depends on the subject, exam board, paper and exam series.
How students should use grade boundaries
Grade boundaries are useful for understanding results, but students should not build their revision plan around trying to guess them.
Instead, focus on:
- Understanding the specification, so revision covers the topics that can actually be examined.
- Practising timed exam questions, rather than only reading notes or making flashcards.
- Marking work with mark schemes, so students learn how examiners award marks.
- Keeping an error log, so repeated mistakes become clear revision priorities.
- Using mocks diagnostically, to identify weak areas while there is still time to improve.
Mocks are especially useful because they show where knowledge gaps and exam-technique issues are before the final exams. Parents can help by focusing on progress and next steps rather than treating a mock grade as a final prediction.
What parents should focus on after mocks
A disappointing mock result can feel discouraging, but it is not a final outcome. The most useful response is to identify what went wrong and make a focused plan.
Encourage your child to:
- Review the mock paper and feedback carefully.
- Identify the two or three topics that cost them the most marks.
- Redo similar exam questions under timed conditions.
- Correct mistakes using the mark scheme.
- Ask for help early if a topic still feels unclear.
Small-group tutoring can also help students rebuild confidence, stay accountable and receive structured support in the areas they find hardest. Tutorelli offers online KS3, GCSE and A-Level tutoring in small groups, with structured lessons and revision support. See how Tutorelli’s small-group lessons work.
Frequently asked questions
Are GCSE grade boundaries the same for every exam board?
No. Each exam board sets grade boundaries for its own papers and exam series. AQA, Pearson Edexcel and OCR boundaries can differ because their papers, mark schemes and student cohorts are different.
Can a student predict their final grade from a mock?
A mock is a useful indicator, but it is not a precise prediction. It is best used to identify gaps in knowledge, improve exam technique and guide the next stage of revision.
Is Grade 4 a pass at GCSE?
Yes. Grade 4 is a standard pass, while Grade 5 is a strong pass. GOV.UK explains the 9 to 1 GCSE grading scale and the position of Grades 4 and 5.
Is Grade 5 better than Grade 4?
Yes. Grade 5 is higher than Grade 4 and is often viewed more favourably by schools, colleges and employers.
Where can students find official grade boundaries?
Official grade boundaries are published by the relevant exam board on results day. Students should check the exam board and exam series that apply to their qualification. AQA publishes its grade boundaries on its official grade boundaries page.
