Overview of Grading Scale
The A Level grading system ranges from A* (highest) to E (minimum passing grade), with U indicating an unclassified or failed result. Each grade is designed to reflect a student’s understanding and mastery of the subject material. The full range is as follows:
- A* – Outstanding performance
- A – Excellent understanding
- B – Very good comprehension
- C – Good performance
- D – Satisfactory
- E – Minimum passing grade
- U – Unclassified, below pass level
AS Level Grades
AS Levels, which represent the first year of an A Level course, are graded differently. They do not include the A* grade and are assessed from A to E. While many schools no longer require AS exams, understanding their structure is still useful for tracking academic progress in year one.
For students considering online study routes, it’s helpful to review the Key Stage 5 curriculum to understand how A Level studies are structured and graded in flexible learning environments.
How Are A Level Grades Determined?
Examination Structure
A Level grades are primarily awarded based on final exams taken at the end of a two-year course. These exams challenge students to apply their subject knowledge, think critically, and construct reasoned arguments under timed conditions. In some subjects, practical work or coursework plays a supporting role, but written assessments remain the foundation of most grades.
To support learners preparing for these final exams, many schools provide tailored exam resources. For those learning online, our exam board guidance outlines the structure and expectations of each subject, helping students stay confident and organized.
Modular vs. Terminal Exams
Before reforms in 2015, students could take modular exams throughout the year, spreading the pressure across multiple sittings. Today, A Levels follow a linear format, meaning all assessments happen at the end of the course. While this approach demands consistent effort over two years, it creates a fairer and more standardised benchmark for performance.
This shift also aligns with the broader trend in UK education for more rigorous qualifications, as highlighted by Study in UK’s detailed grading breakdown, which offers a clear comparison across different exam types and academic levels.
Grade Boundaries Explained
Each year, exam boards like AQA, OCR, and Edexcel publish grade boundaries—the minimum number of marks needed to achieve each grade. These aren’t fixed in advance. Instead, they are adjusted after marking is complete to ensure fairness across varying levels of exam difficulty.
For example:
- A particularly challenging paper might lower the boundary for an A.
- An easier paper could raise it to maintain grade integrity.
This system, explained thoroughly in the UCAS guide to A Level qualifications, ensures that students are evaluated fairly based on overall performance trends.
If you’re preparing from home or abroad, make sure you’re using the right materials. Our equipment requirement page includes a checklist to help students meet the needs of digital and written exams with confidence.

What Does Each Grade Represent?
Percentage Equivalents
Although official A Level grades are awarded based on performance bands rather than fixed percentages, many educators and students use general guidelines to understand what each grade might represent:
- A*: Typically awarded for scoring 90%+ in A2 modules
- A: Around 80–89%, showing excellent understanding and analysis
- B: Roughly 70–79%, indicating strong subject knowledge
- C: About 60–69%, reflecting solid comprehension
- D: 50–59%, demonstrating satisfactory performance
- E: 40–49%, the minimum pass grade
- U: Below 40%, unclassified
These percentage benchmarks help students set realistic expectations and monitor progress throughout the academic year. At each level of the curriculum, clarity on these targets helps learners build confidence. Explore the KS4 curriculum for insights into how these performance indicators are introduced before advancing to A Levels.
Academic Standards
A Level grades are more than numbers—they reflect essential academic competencies. A high grade in subjects like Physics or Economics not only shows subject mastery but also demonstrates problem-solving, critical thinking, and communication skills. These qualities are central to university success and career readiness.
Many universities consider A Levels as one of the most reliable indicators of academic potential. The Study in UK platform highlights how these grades align with global expectations, making A Levels highly regarded internationally.
A Levels vs. Other Qualifications
While A Levels offer subject depth, other qualifications like the International Baccalaureate (IB) or Advanced Placement (AP) are known for breadth. Each system has its strengths, but A Levels allow students to specialise early—often in areas tied directly to their university plans or career aspirations.
For example, a student taking A Levels in Maths, Biology, and Chemistry may be tailoring their studies toward medicine or engineering. This focus is part of what makes A Level grades so impactful. To understand how this fits into a flexible online learning journey, review our Key Stage 5 learning structure, designed to mirror the academic rigor expected in traditional settings.

Conclusion
Understanding what the grades for A Levels mean goes far beyond academic letters. These grades reflect a student’s depth of knowledge, skill development, and readiness for higher education or the professional world. Whether aiming for an A* in Mathematics or working hard to move from a C to a B in English Literature, every grade earned is part of a larger story of growth.
For parents and students planning ahead, knowing how grades are structured and assessed is a powerful tool. It allows for smarter goal-setting, informed university applications, and better support along the way. From exam board details to KS5 program structures, the resources are available to help guide every learner toward their goals.
At every step, preparation, support, and a clear understanding of expectations can turn potential into performance. For more information about our curriculum pathways or to explore sample classes, visit our teaching staff page and discover how strong academic foundations are built every day.
With the right structure and guidance, A Level grades can become not just academic milestones—but stepping stones to a meaningful future.
