A Level Grading System: Grades, Boundaries & UCAS Points

A-Levels are the standard Year 12 to Year 13 qualification across the UK and most British-curriculum schools in Dubai. The grading scale looks simple (A* down to E), but the mechanics underneath catch most students out: percentage conversions, shifting boundaries, UCAS points, and how international boards differ from UK domestic ones. This guide breaks it down using actual published data, with the UAE-specific context that most articles skip. At Ignite Training Institute, we’ve worked with A-Level students across Cambridge International and Pearson Edexcel International for years, and the questions are almost always about the same five things.

What Is The A-Level Grading System?

The A-Level grading system uses a six-grade letter scale: A*, A, B, C, D, E, with U (ungraded) below E. A* is the highest grade; E is the minimum pass. The scale is the same across Cambridge International, Pearson Edexcel International, AQA, OCR, and other boards.

The A* To E Scale (Plus U)

Each grade represents a band of performance, not a single percentage. A* sits at the top tier (typically 90% and above). E sits at the pass threshold (around 40%). Anything below E is recorded as U (ungraded), which carries no UCAS value and is treated as a fail by universities.

Why The A* Was Introduced?

The A* was added in 2010 to distinguish the very top performers. Before then, A was the highest grade, but the proportion of students achieving an A had grown to the point where universities couldn’t differentiate between strong and exceptional candidates. The A* solved that. It’s harder to achieve than an A and signals genuine subject mastery.

AS Level VS Full A-Level Grading

AS Level (Advanced Subsidiary) is the first half of an A-Level. It’s graded A to E only, with no A*. The A* exists only at the full A-Level (A2) stage. Some students take AS as a standalone qualification; others use it as a stepping stone to the full A-Level. UCAS treats AS Levels as worth roughly 40% of the equivalent A-Level points.

Cambridge IGCSE 9-1 vs A-Level: Why The Scales Are Different?

A common point of confusion: Cambridge has rolled out a 9-1 numerical scale on some IGCSE subjects, mirroring the UK GCSE reform. This does not affect A-Level grading. Cambridge International A-Levels still use A*-E. If you’ve taken Cambridge IGCSEs graded 9-1, your A-Levels two years later will be back on letters.

A-Level Grades And Their Percentage Ranges

Here’s the indicative grade-to-percentage mapping with UCAS points alongside.

Grade	Indicative Percentage	What It Means	UCAS Points
A*	90% and above	Outstanding performance	56
A	80% to 89%	Excellent	48
B	70% to 79%	Very good	40
C	60% to 69%	Good	32
D	50% to 59%	Satisfactory	24
E	40% to 49%	Minimum pass	16
U	Below 40%	Ungraded (fail)	0

How The Percentage Ranges Actually Work?

The percentages above are guides, not hard cut-offs. They describe what each grade typically corresponds to, but the actual threshold depends on the exam paper, the year, and the board. 

A student scoring 87% in one June session might earn an A; a student scoring 87% in a different session might earn the same A even though the raw percentages look identical, because the boundaries were adjusted for paper difficulty.

Why Percentages Aren’t Fixed (Raw Marks vs UMS)

Cambridge International uses a system called the Uniform Mark Scale (UMS) for some qualifications, which converts raw marks into a standardised score. Pearson Edexcel International uses a similar approach. The reason: a single subject is taken across multiple papers, and sometimes multiple sessions, and the raw difficulty varies. UMS smooths that out so a student’s reported score reflects ability, not the luck of which year they sat the exam.

Cambridge International’s Percentage Uniform Marks (PUM)

Cambridge International publishes Percentage Uniform Marks (PUM) for AS and A-Level subjects, expressed as a number out of 100 alongside the letter grade. A PUM of 92 in an A grade tells a different story than a PUM of 81 in the same A grade. Universities and parents use it to see exactly where the student sat within a band.

How Are A-Level Grades Calculated?

A-Level grades are calculated through a four-step process that varies slightly by board but follows the same logic.

First, you sit exams and complete any coursework or practical components. Each paper is marked against the official mark scheme, producing a raw mark.

Second, the board converts raw marks into uniform marks. Cambridge uses UMS / PUM; Edexcel uses unit-based uniform marks. AQA and OCR skip this and use raw marks directly. Uniform marks adjust for paper difficulty.

Third, the board sets grade boundaries for the session using comparable outcomes (covered next).

Fourth, your aggregated marks across all papers are compared against the boundaries, and your final grade is awarded. For modular qualifications, this happens once all units are complete, for linear qualifications, at the end of Year 13.

Not every component is counted the same way. Coursework usually counts toward your final grade. Practical work in the sciences usually does not. For example, in Cambridge International A-Level Biology (9700), the lab-based practical paper is part of the main grade and is included in your final mark. 

But in some UK domestic Biology specifications, the practical is separate and graded only as Pass or Fail (the Practical Endorsement). Same subject, different boards, different rules. Always check your subject specification before assuming how each component is counted.

UCAS Tariff Points For A-Level Grades

UCAS tariff points convert your A-Level grades into a single numerical score that UK universities (and many international institutions accepting UK qualifications) use to compare applicants. This is the system that turns AAB into 136 points and BBB into 120.

The Full UCAS Points Table

A* equals 56 points, A equals 48, B equals 40, C equals 32, D equals 24, and E equals 16. The values are spaced 8 points apart between consecutive grades. This makes the maths simple: every grade you move up adds 8 points to your total. These values are confirmed by the official UCAS tariff table, which has remained unchanged since the 2017 framework update.

Common University Targets

AAA = 144 UCAS points. AAB = 136. ABB = 128. BBB = 120. CCC = 96. A course asking for “120 points” can be met by BBB, ABC, or AAD (48+48+24). A course asking for “AAA” specifies the exact grades. Always read the actual offer wording.

How AS Levels Convert To UCAS Points

AS Levels carry roughly 40% of the equivalent A-Level points (A=20, B=16, C=12, D=10, E=6). In England, AS Levels are now standalone and don’t feed into the final A-Level grade. Cambridge International still operates AS as both a standalone and as the first half of a full A-Level.

When UCAS Points Matter (And When They Don’t)

UCAS points matter most for post-1992 UK universities and many UAE branch campuses. Russell Group universities and competitive courses (Medicine, Oxbridge, Imperial, LSE) typically specify exact grades like AAA or A*AA rather than a points target. The points system is a flexibility tool.

How Grade Boundaries Are Set Each Year?

Grade boundaries are the minimum raw mark required to achieve each grade. They change every session for every subject. Understanding why is one of the most useful things an A-Level student can know.

The “Comparable Outcomes” Approach Explained

Boards don’t set grade boundaries before an exam is taken. They set them after marking, using a process called comparable outcomes. The board looks at the cohort’s prior attainment (usually GCSE or IGCSE results), compares this year’s paper performance to historical patterns, and adjusts thresholds so that grade distribution stays consistent across years. If a paper is unusually hard, the threshold drops. If it were unusually easy, it rises. The point is fairness: a student isn’t disadvantaged for sitting a tougher paper.

When Each Board Releases Boundaries

Cambridge International releases grade thresholds twice a year, after the June and November sessions. Pearson Edexcel International runs January and June sessions and releases boundaries after each. AQA and OCR (UK domestic boards) release boundaries on UK results day in mid-August. All boards publish these on their official websites, and they’re public.

Real Example: Cambridge International A-Level Maths 9709

Cambridge International A-Level Mathematics (9709) is one of the most widely-taken subjects in UAE schools. For the June 2024 session, Paper 1 (Pure Mathematics 1) thresholds sat in the typical range: A required around 60 out of 75 marks; E required around 33 out of 75. 

Across the full subject, A* required roughly 80% of the total uniform mark and E required roughly 40%. These numbers shift every session, which is why students should always pull the latest thresholds from the Cambridge International published grade thresholds page rather than assume last year’s apply.

Results Day, Resits, And Appeals For A Levels

What happens after the exams matters as much as the exams themselves. 

When A-Level Results Are Released

Cambridge International June results release in mid-August (November session results in January). Pearson Edexcel International January results come in early March; June results in mid-August. UK domestic A-Levels (AQA, OCR) release on UK results day in mid-August.

Practical Endorsements For Sciences

For science A-Levels (Biology, Chemistry, Physics), some boards award a separate Practical Endorsement graded Pass or Fail, independent of the main grade. It reflects lab competence assessed across the two years. Many UK universities and a growing number of UAE universities require a passed endorsement for science degrees, so check your target’s policy before assuming a strong main grade is enough.

How Remarks And Appeals Work

If your grade looks lower than expected, request a remark through your school (Cambridge calls it a Review of Marking; Edexcel calls it Enquiry About Results). There’s a fee, refunded if the grade changes, with 4 to 6 weeks turnaround. If a remark doesn’t change the result, formal appeals exist but are rare and need evidence of administrative error.

Resit Options

You can resit individual units (Edexcel International, Cambridge modular) or the full subject (Cambridge linear). Fees apply per unit or subject, and the next session is usually about six months away. Universities treat resits differently: some accept them at face value, others favour first-attempt grades. If you’re resitting to meet a conditional offer, check with the university first.

Ignite: A-Level Tutors In Dubai Helping Students Hit Their Target Grades

Whether you’re aiming for AAA at Cambridge International or rebuilding from a weak AS year on Edexcel, structured support changes outcomes. Our A-Level tutors in Dubai work with students across all main subjects, with focused attention on past papers, mark schemes, and the specific assessment style of each board.

One student, Nishchaya, worked with Ignite for two years through O Levels and AS Maths and Physics. Starting from a position where the subjects felt unmanageable, he reached 81% by the end of his AS year through consistent weekly tutoring and structured paper practice. The improvement came from working through real exam questions under timed conditions, not from cramming theory. That’s the model we apply to every A-Level student.

If you’d like to see how it works for your subjects, book a free demo class with Ignite’s A-Level tutors and we’ll talk through your current grades and target.

FAQs

1. What Grade Is 60% At A Level?

60% typically corresponds to a C grade at A-Level. The exact threshold shifts each year based on the board’s grade boundary calculation, but 60% to 69% is the standard C band.

2. What Grade Is 70% At A Level?

70% typically corresponds to a B grade at A-Level. The B band sits at roughly 70% to 79%, again subject to small annual adjustments by the exam board.

3. Is E A Pass At A Level?

Yes, E is the minimum passing grade at A-Level. It corresponds to roughly 40% of the maximum mark. While E is technically a pass, most universities and competitive programmes require grades in the C to A* range for entry.

4. Is D A Pass At A Level?

Yes, D is a pass at A-Level. It sits between E (minimum pass) and C (good). A D is around 50% to 59%. Many UK and UAE university courses accept a D for entry, particularly less competitive programmes and those using the UCAS points system.

5. What Is The Highest A-Level Grade?

The highest A-Level grade is A*. It was introduced in 2010 to distinguish exceptional performance from the standard A grade. To achieve an A* in most boards, students need around 90% on the full A-Level (with specific A2-stage performance requirements depending on whether the qualification is modular or linear).

Conclusion

The A-Level grading system looks simple but has real depth. The A*-E scale is consistent across boards, but the percentage thresholds shift each year through comparable outcomes. UCAS points convert grades into a universal score (A*=56 down to E=16). 

Most UAE students sit Cambridge International or Pearson Edexcel International, both using uniform mark systems. For UAE applications, KHDA attestation and individual university policies matter as much as the grades themselves.
