A-Level to US GPA conversion table
| A-Level grade | US GPA (4.0 scale) | US letter equivalent |
|---|---|---|
| A* | 4.0 | A+ |
| A | 3.7 | A− |
| B | 3.0 | B |
| C | 2.0 | C |
| D | 1.0 | D |
| E | 0.0 | F (fail) |
Some evaluation services use a simpler scale where A = 4.0 (same as A*). This calculator uses the more nuanced version where A* = 4.0 and A = 3.7, which is common in US admissions.
How A-Levels compare to US high school
A-Levels are considered more rigorous than standard US high school courses. They're roughly equivalent to AP (Advanced Placement) courses in terms of difficulty and depth. US universities typically treat A-Levels favourably in admissions:
- Grade A or A* in an A-Level is often considered equivalent to a score of 4 or 5 on an AP exam
- Many US universities award college credit for A-Levels with grades A–C
- A-Levels demonstrate subject mastery and academic rigour, which is highly valued by selective US universities
If you're a UK student applying to US universities, your A-Levels are a strong qualification. Use our UCAS Tariff Calculator for UK applications, and this converter for US applications.
Example conversions

| AAA | 3.7 | Strong A− average |
| AAB | 3.47 | B+/A− average |
| BBB | 3.0 | Solid B average |
| CCC | 2.0 | Minimum for many US colleges |

Frequently asked questions
How do I convert A-Level grades to US GPA?+
Each A-Level grade maps to a US GPA value: A* = 4.0, A = 3.7, B = 3.0, C = 2.0, D = 1.0, E = 0.0 (fail). The overall GPA is the average of all your A-Level subjects, weighted equally. This is a reference estimate — official conversion depends on the credential evaluation service (WES, SpanTran, etc.) and the specific US university.
Is an A* at A-Level equal to a 4.0 GPA?+
Yes, in most conversion tables A* is treated as 4.0 (the maximum). However, some US universities separate A* and A differently. A* is often considered equivalent to a US A+ (4.0), while an A might be closer to 3.7. This calculator uses A* = 4.0 and A = 3.7 for a more nuanced conversion.
How does WES convert A-Levels to US GPA?+
WES (World Education Services) typically converts UK A-Levels to US GPA using a scale where A* and A = 4.0, B = 3.0, C = 2.0, D = 1.0, and E = 0.0. Some evaluations use a more granular scale with A = 3.7. The exact conversion depends on the evaluation type and the receiving institution's requirements.
What is a good A-Level to US GPA conversion?+
AAB (typical competitive university offer) converts to roughly 3.6–3.8 GPA. AAA converts to 3.8–3.9. A*AA is around 3.9. Three Cs (CCC) converts to roughly 2.0. For US admissions, a 3.0+ from A-Levels is generally considered competitive, and 3.5+ is strong.
Do US universities accept A-Levels?+
Yes, US universities widely accept A-Levels as a rigorous academic qualification. Many award college credit for A-Levels (typically A or B grades), similar to AP courses. Some universities may require a credential evaluation (like WES) to convert your grades to the US GPA scale for admissions decisions.
What if I have mixed A-Level and AS-Level grades?+
This calculator converts A-Level grades only. AS-Levels are typically not included in GPA calculations for US admissions — they're considered separate qualifications. Focus on your full A-Level grades. If you only have AS-Levels, you can use them as a rough indicator but the conversion is less standardised.
Is the A-Level to US GPA conversion the same for all subjects?+
Yes, the conversion is the same regardless of subject. However, US admissions officers consider the rigour of your course load. A student with A-Levels in Mathematics, Further Mathematics, and Physics is often viewed more favourably than someone with three less demanding subjects, even with the same converted GPA.
Do I need a credential evaluation for US university applications?+
Some US universities require a credential evaluation from services like WES, SpanTran, or ECE as part of the application process. Others will evaluate your A-Level transcripts internally. Check the admissions requirements for each university you're applying to — they'll specify whether an external evaluation is needed.
