Step by step

How to use this
calculator

Choose your output scale — 4.0 or 4.33

Use 4.0 for most US universities. Choose 4.33 only if your target institution explicitly uses it — this is the scale that gives A* (4.33) its own distinct value above plain A (4.0).

Add each A-Level subject with its grade

Enter grades as A*, A, B, C, D, E, or U. A* maps to A+ in US terms; U (Ungraded) maps to F. On the 4.0 scale, both A* and A earn 4.0 — only the 4.33 scale distinguishes them.

Optionally add AS-Levels and EPQ

AS-Levels and EPQ use the same A–E grade scale, so you can include them here. Flag them separately in your actual application — US universities weight full A-Level results (2 years) more heavily than AS-Level (1 year).

The conversion

How A-Level grades
map to US GPA

A-Level grades are awarded on a six-level passing scale: A*, A, B, C, D, E — plus U (Ungraded) for work that doesn't meet the E threshold. Each maps to a GPA point value based on where it sits relative to the standard US letter grade scale.

GPA = Σ(points) / number_of_subjects (equal credit) or GPA = Σ(points × credits) / Σ(credits) (credit-weighted) 4.0 scale: A* = 4.0, A = 4.0, B = 3.0, C = 2.0, D = 1.0, E = 0.5 4.33 scale: A* = 4.33, A = 4.0, B = 3.33, C = 2.67, D = 1.33, E = 0.67 Example: A*, A, B (4.33 scale, equal credits): GPA = (4.33 + 4.0 + 3.33) / 3 = 3.89

The 4.33 scale is the one that properly distinguishes an A* from a plain A. On the 4.0 scale, both cap at 4.0 because the US system doesn't typically have a value above 4.0. If A* recognition matters, choose 4.33.

Predicted vs actual

How A-Level grade combinations
translate to US GPA

Three students with the same teacher-predicted grades of A*AA. Their actual results differ — and so does the GPA that US admissions sees on the 4.33 scale.

✓ A*, A, A — Strong Application

Predicted A*AA delivered — US GPA: 4.11 on the 4.33 scale

A* (4.33) + A (4.0) + A (4.0) = 12.33 ÷ 3 = 4.11. Competitive at highly selective US schools. Many universities will grant credit for A and A* subjects in relevant fields.

A* + A + A on 4.33 scale: GPA = (4.33 + 4.0 + 4.0) / 3 = 4.11 ✓ Competitive: most selective US programs
⚠ A, B, B — Grades Slipped from Predictions

Predicted A*AA, achieved ABB — GPA drops to 3.33

A (4.0) + B (3.0) + B (3.0) = 10.0 ÷ 3 = 3.33. Competitive at most US universities but below typical threshold for highly selective programs (need 3.7+). If a UK university made a conditional offer of A*AA, it may be withdrawn.

A + B + B on 4.0 scale: GPA = (4.0 + 3.0 + 3.0) / 3 = 3.33 ⚠ Fine for most US schools; borderline selective
✗ A, C, B — Significant Grade Pressure Impact

ACB result: GPA 3.0 — below competitive threshold for selective programs

A (4.0) + C (2.0) + B (3.0) = 9.0 ÷ 3 = 3.0. A C in one A-Level significantly drags the average. For most US selective programs (expected 3.5+), this profile would require strong extracurricular or test scores to compensate.

A + C + B on 4.0 scale: GPA = (4.0 + 2.0 + 3.0) / 3 = 3.00 ✗ Below competitive threshold for top-25 US schools

Common questions

A-Level GPA Calculator FAQ

How do A-Level grades convert to US GPA?

On 4.0 scale: A* = A = 4.0, B = 3.0, C = 2.0, D = 1.0, E = 0.5, U = 0.0. On 4.33 scale: A* = 4.33, A = 4.0, B = 3.33, C = 2.67, D = 1.33, E = 0.67, U = 0.0.

What is an A* in US grade terms?

A* (A-star) is the top UK grade, equivalent to A+ in the US system. On the 4.33 scale it earns 4.33 points; on the 4.0 scale it's capped at 4.0, the same as a plain A.

How many A-Levels do US colleges expect?

Most US universities expect 3 A-Levels. Selective schools may prefer 4, or 3 A-Levels plus strong AS-Levels. Sciences often require specific subjects.

Is an A harder in the UK than the US?

Generally yes. A-Levels are nationally standardised, subject-specific, and assessed by final exam — less grade inflation than the US system. A UK A broadly compares to a strong AP A.

Do US universities award credit for A-Levels?

Many do — especially for A* and A in HL-equivalent subjects. MIT, Caltech, and many state universities have specific A-Level credit policies. Check each registrar directly.

What grade is needed to pass?

E is the minimum passing A-Level grade. U (Ungraded) is a fail. For university admission, most selective schools require at minimum CCC; top schools require AAA or A*AA.

Should I enter AS-Levels here?

You can — AS-Levels use the same A–E scale. But US universities typically value full A-Levels (2 years) more heavily than AS-Levels (1 year). Note the distinction in your application.

Which scale should I choose — 4.0 or 4.33?

Use 4.0 for most US universities. Use 4.33 if the university explicitly uses that scale — it's less common but allows A* to stand out from A.

Can I enter my EPQ qualification?

You can technically enter EPQ since it uses the A–E scale. But US universities usually treat EPQ separately from exam-based A-Levels — check whether your target school considers it.

Why do A* and A give the same GPA on the 4.0 scale?

The 4.0 scale caps at 4.0 — there's no value above it. Both A* and A earn 4.0. The 4.33 scale solves this by giving A* its own value of 4.33.

Does this affect financial aid eligibility?

No — federal financial aid SAP is based on your university GPA once enrolled, not your A-Level conversion. This calculator is a planning tool for applications, not an official academic record.
