What Are A Levels? A Beginner's Guide

After finishing your GCSEs, you've probably started hearing the words A-levels everywhere: on noticeboards, from teachers, in conversations with older students. But no one's actually explained what they are, so here's the answer.

‍

An A-level (Advanced Level) is a UK qualification studied at Sixth Form, the final two years of secondary education, or college, between 16 and 18, over two years, in three or four subjects chosen by you. For many, it's the final stage of school before university. 

‍

In this guide, we'll cover what A level stands for, how it compares to GCSEs and US qualifications, how UCAS points work, and when results day falls.

‍

Let's start with the basics.

Key takeaways

• An A-level (Advanced Level) is a UK qualification studied over two years, usually between ages 16 and 18, in three or four subjects chosen by the student, and for many, it's the final stage of school before university.
• Structure runs chronologically: in Year 12, some students take four subjects and narrow down, others start with three; AS-level is a separate, standalone qualification that many don't sit at all. In Year 13, students study three or four subjects in depth, with the A-level grade determined entirely by exams at the end of the year. 
• Compared to GCSEs, A-levels cover far fewer subjects (3-4 vs 8-10) in much greater depth, use an A*-E grading scale instead of GCSE's 9-1, and demand significantly more independent study.
• There's no exact US equivalent to an A-level. AP exams and the IB Diploma are the closest comparisons, and some universities use an approximate reference point (AP 5 near an A-level A or A*), though there's no single, universal conversion. 
• Each A-level grade converts to a fixed UCAS Tariff score, A* = 56, A = 48, B = 40, C = 32, D = 24, E = 16, which universities use to compare applicants across qualification types.
• A-level results day is set by JCQ and falls on the same Thursday across all exam boards; the provisional date for 2027 is on August 12th, though this won't be confirmed until closer to the time.

What does "A-level" actually stand for?

A-level stands for Advanced Level. It's a subject-based qualification you study for two years, usually between 16 and 18, at Sixth Form or college, in three or four subjects you choose yourself, studied in depth rather than broadly.

‍

Where it sits matters just as much. A-levels are RQF Level 3 qualifications, ranked under the Regulated Qualifications Framework, the system Ofqual uses to indicate the level of knowledge, skill, and complexity a qualification involves. Level 3 sits above GCSEs (Level 2) and is the standard most UK universities expect. 

‍

A-levels sit at the same RQF level as a Level 3 apprenticeship, a BTEC National, a T-Level, and the Extended Project Qualification (EPQ). That doesn't mean universities or employers treat them identically, some courses only accept specific qualifications, so it's still worth checking entry requirements before you choose. 

How are A-levels structured?

In England, A-levels are a two-year linear qualification. Your final grade comes entirely from exams at the end of Year 13, so nothing you do in Year 12 counts toward your A-level result on its own.

‍

Here's what each year is actually for:

• Year 12: Some students start with four subjects and narrow to three by Year 13; others commit to three subjects from the start. Either way, this year builds the foundation for the depth that follows.
• Year 13: Whichever route you took, you'll spend this year going deeper into your three or four chosen subjects, building toward the final exams that determine your actual A-level grade and the qualification universities assess you on. 

‍

Wales and Northern Ireland still run A-levels differently, with AS results contributing to the final A-level grade, so check which system applies if you're studying outside England.

‍

You'll sit exams with one of the UK's main exam boards, AQA, Edexcel, OCR, or WJEC/Eduqas, and your final grade lands somewhere on the A*-E scale. Exact paper structure and content vary by subject and exam board, so it's worth checking your specific board's requirements once you've chosen your subjects.

What's the difference between GCSE and A-level?

The jump from GCSE to A-level is bigger than most students expect. GCSEs test you across a wide spread of subjects, while A-levels ask you to go much deeper into far fewer of them, with far more independent study expected along the way.

‍

Here's how the two compare side by side:

What is an A-level equivalent to in the US?

There's no single US qualification that matches an A-level exactly. The US high school diploma isn't the right comparison either, it's a general graduation certificate, not a subject-specific qualification, so the two systems aren't structured in a way that makes direct comparison useful. 

‍

The closest comparisons are Advanced Placement (AP) exams and the International Baccalaureate (IB) Diploma. AP exams are graded 1 to 5, and some universities use an approximate comparison, an AP score of 5 sitting near an A-level A or A*, and an AP 4 near a B or C, but there's no single, universal conversion, each university sets its own credit and admissions equivalencies. 

‍

The IB Diploma is scored differently again, out of 45 points across six subjects plus a core, making it broader but less subject-specific than your A-levels. Because A-levels involve two full years focused on just three or four subjects, a strong A-level grade often signals deeper subject mastery than the equivalent AP score. 

‍

US admissions officers generally recognise A-levels as rigorous, university-preparatory work, comparable in depth to introductory college courses.

Which is harder, A-level or college?

This question usually mixes up two different things. In the UK, "college" often just means the sixth form or FE college where you study your A-levels, not a separate qualification, so the comparison people usually mean is A-levels versus the first year of university, in the UK or US.

‍

Here's the logic: AP exams, the closest US equivalent to A-levels, are designed to approximate introductory, first-year college content. A-levels are then generally considered more in-depth than AP, since you spend two full years on just three or four subjects rather than sampling multiple AP courses.

‍

So the honest answer is: it's less about which is "harder" and more about what each tests. A-levels push you deeper into fewer subjects over two years, while a first year of university often broadens back out before you specialise further.

How many UCAS points is an A-level worth?

Once your A-level grades come in, universities convert them into UCAS Tariff points, a standardised score used to compare applicants across different qualification types. Each grade carries a fixed point value, and you simply add up the points across your subjects to get your total.

‍

Here's how each A-level grade converts to UCAS points:

• A* = 56 points
• A = 48 points
• B = 40 points
• C = 32 points
• D = 24 points
• E = 16 points

‍

For example, three A-levels at grades A*AB would give you 56 + 48 + 40 = 144 points. For the full breakdown, including mixed qualifications and how to maximise your total, see our complete guide to UCAS points.

When is A-level results day?

A-level results day is set by the Joint Council for Qualifications (JCQ), so it's the same date across every exam board, AQA, Edexcel, OCR, and WJEC/Eduqas. Results are always released on a Thursday in mid-August.

‍

For 2027, the provisional date is Thursday 12 August, based on exam boards' published timetables. This isn't confirmed yet, JCQ typically finalises results dates in spring of the relevant year, so treat this as a working date rather than a certainty.

‍

Check the confirmed date closer to the time, either through your school or JCQ's official announcement.

Choosing which A-levels to take is harder than it looks. Get it wrong, and you could rule yourself out of university courses months before you even apply, since many degrees list specific subject requirements you won't discover until it's too late.

That's the gap most students hit first: picking subjects based on interest alone, without checking what universities actually expect for the course they want. Before you commit, it's worth checking what different degrees and universities look for by subject.

Our A-level requirements guide breaks this down clearly, so you can choose subjects with your university options in mind, not just your current interests.

FAQs

What does "A-level" stand for?

A-level stands for Advanced Level. It's a UK qualification studied for two years, usually between 16 and 18, and it sits at RQF Level 3, the same level as a BTEC National, a T-Level, or a Level 3 apprenticeship.

What's the difference between A-level and GCSE?

GCSEs cover 8-10 subjects broadly, while A-levels focus on just 3-4 subjects in much greater depth. GCSEs use a 9-1 grading scale; A-levels use A*-E, and A-levels demand far more independent study.

What is an A-level equivalent to in the US?

There's no exact match. AP exams and the IB Diploma are the closest comparisons, not the US high school diploma. Some universities use AP score 5 as roughly comparable to an A-level A or A*, but there's no single, universal conversion. 

Which is harder, A-level or college?

It's not really a "harder or easier" comparison. A-levels push you deeper into fewer subjects over two years, while a first year of university or college typically broadens back out before you specialise further.

How many UCAS points is an A-level worth?

Each A-level grade carries a fixed UCAS Tariff value: A* = 56, A = 48, B = 40, C = 32, D = 24, E = 16. Add your grades together to get your total.

When is A-level results day?

Results day is set by JCQ and falls on the same Thursday across all exam boards. For 2027, the provisional date is Thursday 12 August, though this isn't confirmed until closer to the time.

Conclusion: Understanding A-levels

You now know what A-levels actually are: a two-year, RQF Level 3 qualification that sits alongside BTECs and T-Levels as the final stage of school for many students before university.

‍

That foundation makes everything else easier to place. GCSEs test breadth, A-levels test depth, and while there's no exact US equivalent, they're broadly comparable to a first year of university.

‍

Once results arrive, your grades convert into UCAS points, feeding into your applications, but your subject choices are locked in long before then. That's why it pays to test your interests first.
