Navigating the UK secondary education system can be confusing, especially if you’re unfamiliar with the different stages and exams. To keep things simple, the two main qualifications you need to know are GCSEs and A Levels.

But what do they really mean? How are they different? And why are they so important?

Whether you’re a student planning your next steps or a parent supporting your child through their academic journey, understanding the relationship between GCSEs and A Levels is crucial. In this guide, we’ll break it down: what these qualifications are, how they compare, and why they matter. 

From understanding their structure to knowing how they’re viewed by universities and employers, here’s everything you need to know.

What’s the difference between GCSEs and A Levels?

GCSEs are important exams taken at the end of compulsory secondary education. They cover core subjects like English and Maths as well as subjects students choose themselves. For most people, they come at the end of Year 11 (age 15-16). On the other hand, A Levels are more advanced qualifications focusing on fewer subjects. Exams happen at the end of Year 13 (age 17-18). While students normally take seven to ten GCSEs, three or four A Levels is common. 

Here’s the breakdown:

• GCSEs (General Certificate of Secondary Education) are exams taken at the end of Year 11, when students are around 15 or 16. These qualifications cover a wide range of subjects, from core areas like English Language and Maths to optional ones like History, Art or Computing. They form the baseline for your post-16 options and are compulsory for everyone in the UK.
• A Levels (Advanced Levels) usually come next, taken in Year 13 (age 17-18). These qualifications let students specialise in just three or four subjects they’re passionate about, that align with their career goals. A Levels go into much greater depth than GCSEs, which is why they’re considered more advanced and challenging.

Here’s a quick comparison:

	GCSE	A Level
Age Group	15-16 years old	16-18 years old
Time Needed	2 years (Years 10 and 11)	2 years (Years 12 and 13)
Number of Subjects	Typically 7-10	Usually 3-4
Level of Depth	Broad and foundational	Specialised and advanced
Exams and Coursework	Mix of written exams and coursework	Heavy focus on exams; limited coursework
Difficulty	Designed for all abilities	Designed for academic depth

Although it’s becoming less common, you might come across AS Levels. While a full A Level course takes two years, AS Levels take just one. Think of them as a stepping-stone between the breadth of GCSEs and the depth of A Levels.

Which is better, A Level or GCSE?

If you’re comparing GCSEs and A Levels, neither is objectively “better” because they serve different purposes. Think of GCSEs as the foundations of a house and A Levels as the interior design. You need GCSEs to progress to A Levels. 

Most sixth-form colleges ask for specific GCSE grades in subjects related to your A Level choices. You also normally need a pass (that’s a 4) in core subjects like Maths and English Language.

Without strong GCSEs, you might struggle at A Level. But it’s at A Level where your choices really start shaping your future.

• GCSEs are important because they show a broad base of knowledge and key skills, like literacy and numeracy. They can be a great stepping stone into qualifications like BTECs or apprenticeships, as well as the world of work.
• A Levels are more significant for university admissions and job applications, as they reflect your specialisations and interests. Solid A Level grades are important for leading Russell Group and Non-Russell Group universities as well as degree apprenticeships and more competitive careers like Law, Medicine or Accountancy.

In short, they complement each other. GCSEs are the stepping stone, while A Levels are the launch pad.

Do universities look at GCSEs or A Levels?

Universities look at both GCSEs and A Levels. But your A Level grades carry more weight.

Universities mostly use A Levels to assess your suitability for a course. They’ll give offers based on your A Level grades (say, AAB or AAA) or the equivalent UCAS points.

That said, GCSEs still matter, especially for competitive courses or universities. Most universities require at least a grade 4 (a pass) in English Language and Maths. Some courses also have extra GCSE requirements. For instance, a Medical degree might ask for at least grades 6/7 in Science subjects. An Economics degree might ask for similar grades in Maths. 

Your GCSE profile can also act as a tiebreaker for competitive applications. Universities prioritise students with a consistent record of strong academic performance throughout school. So if it comes down to students with straight As at A Level, but one boasts 7s, 8s, and 9s at GCSE while the other has a few 4s and 5s… you can guess who’ll come out on top.

If your grades have just fallen short, remember retakes are a great option for both GCSE and A Level.

Do jobs look at GCSEs or A Levels?

Like universities, employers look at both GCSEs and A Levels. But the focus differs depending on the role. For entry-level jobs, GCSEs are usually more relevant, while A Levels come into play for highly-paid roles requiring more skills or qualifications. Of course, if you’re applying for graduate jobs, your degree classification will matter too.

GCSEs are often used as a benchmark for basic ability, while strong A Levels demonstrate advanced knowledge and commitment.

For instance:

• GCSEs: Many jobs require at least a pass (grade 4) in English and Maths, and some training-based roles (like apprenticeships) may specify certain GCSE subjects.
• A Levels: These are particularly valued for jobs requiring analytical skills, like finance, engineering, or teaching. They’re also useful for competitive apprenticeship schemes and school-leaver programmes.

What GCSE grade is equivalent to an A Level?

There isn’t a direct equivalence between GCSEs and A Levels, because they’re different levels of qualification. In the UK, a pass at GCSE is a “Level 2” qualification. A Levels are a “Level 3” qualification.

But if you’re comparing grades:

• A grade 8 or 9 at GCSE is roughly comparable to an A or A* at A Level (with an obvious step-up in difficulty).
• A grade 6 or 7 at GCSE roughly compares with a B or C at A Level. 
• The two qualifications use different grading systems. GCSEs use a numerical scale (1-9), while A Levels use letters (A*-E).

Here’s a more detailed breakdown.

GCSE Grade	A Level Grade
9/8	A*
7	A/B
6	B/C
5	C/D
4 (passing grade)	E (passing grade)
3 or below	U “unclassified”

Remember, these are only rough grade comparisons. They’re not a direct equivalence. The jump in difficulty between GCSEs and A Levels is significant!

Is 7 a good GCSE grade?

Absolutely. A 7 at GCSE is a great grade. Only 20-30% of students achieve this each year.

A grade 7 in the new GCSE grading system is equivalent to an A or B under the alphabetical system. So if you’re on track for a 7 at GCSE, this is an excellent achievement. It’s also enough to secure entry to most A Level courses.

Here’s how the new GCSE grading system compares to the old alphabetical one:

Numerical Grades	Alphabetical Grades
9	A*
8	A*/A
7	A/B
6	B
5	C
4	D/E

What’s the hardest GCSE to take?

Of course, the hardest GCSEs will depend on your personal strengths. That said, certain GCSEs have a reputation as challenging among students and teachers alike. You won’t be surprised to hear this includes subjects like Maths and Statistics, Triple Science and Modern Languages, as well as essay-based subjects like English Literature and History.

Here are five of the hardest GCSEs and their pass rates. That’s the percentage of students achieving a grade 4 or above.

1. Triple Science

Tackling Biology, Chemistry and Physics in more depth than the standard “Double Award” makes this one of the toughest GCSEs out there. Each subject demands strong analytical and practical skills.

GCSE pass rates by subject: a quick note

Pass rates tell us lots about how students perform in different GCSE subjects. But it’s important to remember they’re not the whole story. Core subjects like Maths and English Language tend to have lower pass rates compared with optional subjects. This isn’t because the exams are super difficult, but because everyone must take them, regardless of ability or interest.

Similarly, the more challenging GCSE subjects, like Further Maths or Triple Science often have higher pass rates. This doesn’t mean they’re “easier” to pass though. It could reflect the academic abilities and dedication of students choosing them.

What are the hardest A Levels to take?

A Levels are all challenging. They’re the pinnacle of secondary education in the UK, designed to give students in-depth knowledge of their subjects and the skills to succeed at university. That said, some subjects stand out as especially difficult. Like Maths, Further Maths and the Sciences. Subjects requiring in-depth analysis like History, Philosophy and English Literature can also be challenging.

Here are the five hardest A Level subjects and their pass rates. A pass at A Level is an “E” or higher.

1. Maths and Further Maths

Maths A Level isn’t just about numbers. It pushes your problem-solving and abstract thinking to the limit. Further Maths goes even deeper with advanced topics like calculus and linear algebra.

If you’re currently working towards exams, we’ve got everything you need. From how to get all A*s to motivational quotes and subject-specific guides covering Maths, English Language, Economics, Chemistry, Biology and more.

A Level pass rates by subject: a quick note

Just like GCSEs, A Level pass rates vary by subject. Generally, subjects like Maths and English Literature have higher pass rates, precisely because of their difficulty! Generally only the most academic students choose them. On the flip side, less challenging subjects like PE and Sociology often see lower success rates.

Remember, pass rates aren’t everything. So treat them with a pinch of salt. The effort you put into your studies will always have the biggest impact on your results.
