Choosing your A Level subjects is a major decision. You have to consider your personal interests, degree aspirations and future career prospects alongside your academic abilities, workload and what’s on offer at your school – it’s a lot!

Among the many factors, one of the most pressing questions is about the difficulty of each subject. While some students want to avoid tricky subjects, others seek out the challenge!

In this guide, we delve into the hardest A Level subjects – with insights into their difficulty levels, exam boards, and comparisons with GCSEs and university study.

Hardest A Level Ranking: The Top Ten

What are the hardest A Levels in order?

Ranking the hardest A Level subjects is a complex task. After all, a topic that one student finds challenging, another might breeze through. Even so, some A Level subjects stand out for their advanced content, abstract concepts, terminology and rigorous exams – such as Further Maths, the Sciences, English Literature and History. 

Here are the top ten hardest A Level subjects, in order.

1. Further Maths

Further Maths easily stands out as the most daunting A-Level subject – essentially counting as two due to its extensive curriculum and demanding content!

With Further Maths, students dive into advanced topics like Core Pure modules, Statistics, Mechanics and Discrete Maths. Just take a look at the AQA or Edexcel specifications to get an idea of the vast amount of topics covered.

Needless to say, this course isn’t for the faint-hearted. It’s tailored for the mathematically inclined, requiring a genuine passion and talent for the subject.

2. Physics

Second on our list is Physics. Delving into the fundamental principles governing the universe, Physics is one of the most intellectually challenging A-Levels. 

Beyond its theoretical complexity lie exams testing comprehension of concepts like electromagnetism, gravitational forces, nuclear physics and thermodynamics. 

With an expansive syllabus (take OCR for example) and a heavy reliance on mathematical reasoning, Physics demands a solid foundation in both maths and scientific inquiry – making it a formidable A Level.

3. Chemistry

A-Level Chemistry is renowned for its difficulty, presenting a significant step-up from GCSE. 

Split into Physical, Organic and Inorganic branches, Chemistry A Level requires mastery of diverse topics (such as electrochemistry, organic compounds and the structure of matter) and a sophisticated understanding of chemical principles. 

From balancing equations to comprehending complex molecular structures and real-world applications, students must navigate Chemistry’s in-depth curriculum – making it a daunting but intellectually rewarding subject.

4. Biology

If there’s one thing A Level Biology is famed for, it’s specialised vocabulary. Students often say they feel they’re learning another language with all the intricate concepts and new scientific terms!

From cellular processes like mitosis to biochemical pathways such as glycogenesis, every corner of this subject demands meticulous study and comprehension. 

For anyone venturing into A Level Biology, dedication and perseverance are essential – as mastering its depth and breadth is no small feat.

5. Maths

We’ve already covered Further Mathematics as our number one hardest A Level… but “regular” Maths isn’t too far behind!

A Level Maths demands both logical reasoning and abstract thinking – making it a challenge for even the brightest students. From calculus to algebra, students must grapple with complex concepts and creative problem-solving. 

Like Further Maths, the breadth and depth of topics makes achieving top grades in A Level Maths a daunting yet rewarding prospect.

6. Philosophy

Studying Philosophy is a unique experience – requiring students to navigate abstract concepts and engage in critical thinking on a profound level. Students say it’s a bit like marmite, you’ll either love it or you’ll hate it!

From dissecting ethical dilemmas to exploring the nature of reality, this essay-based subject demands intellectual rigour and the ability to articulate complex ideas with clarity and precision. 

But for those drawn to the mysteries of the human condition, A-Level Philosophy offers a journey of profound exploration and intellectual growth.

7. History

A Level History demands not only a mastery of vast amounts of historical content (think names, dates, places etc.) but also the ability to critically analyse and interpret complex events and changes. 

From revolutions to geopolitical shifts, students explore intricate narratives and develop nuanced perspectives on historical events. With rigorous exams and a heavy emphasis on essay writing, A Level History specifications test not only knowledge but analytical skills (hello source analysis) and historical interpretation.

8. English Literature

While you might be surprised to see English Literature in this list – it’s an A Level subject that many students struggle with. It requires a deep dive into literary texts and genuine engagement with sophisticated analysis and interpretation. 

From Shakespearean sonnets to modernist novels, every work demands careful scrutiny and insightful commentary. With an emphasis on original thought and nuanced understanding, A Level English Literature specifications test students’ ability to think critically and articulate complex ideas with eloquence and insight.

9. Modern Foreign Languages

OK, so it’s technically not a single subject – but modern foreign languages (no matter what the language) are notoriously challenging.

Studying a foreign language at A Level involves proficiency in listening, reading, writing and speaking. And there’s no getting around it… you’ll need to put the hours in. From mastering grammar to honing pronunciation, students need a diverse array of skills. 

Many A Level language courses also focus on cultural understanding – requiring not only language proficiency, but awareness of cultural sensitivities too.

10. Computer Science

Last on our list is a relatively new A Level subject, Computer Science – introducing students to the intricate world of coding and computer systems. 

From programming languages to data structures and computer architecture, students navigate a complex specification covering computational thinking and problem-solving. What’s more, this A Level subject carefully balances theory and practical application, demanding not only technical proficiency but also creativity and analytical skill.

We’ve included links to A Level specifications across AQA, OCR, Edexcel and Eduqas in this list. To understand more about GCSE and A Level exam boards, how they work (and which is hardest!), read our in-depth guide.

What are the three hardest A Levels?

While everyone’s experience will vary (and “hardest” is totally subjective), the three A Levels named by students and teachers alike are Further Maths, Physics and Chemistry. 

Why?

Well, they’re all renowned for their mixture of complex theoretical content, real-world applications and problem-solving. These subjects all represent a significant step-up from GCSE – with loads of new concepts, terminology and lengthy exams.

Although they’re undoubtedly challenging, you’ll be pleased to learn these subjects don’t have lower pass rates. Across the board, 75% of A Level students achieved a C or above. For Further Maths, Physics and Chemistry, it’s between 73-78%. So very similar!

Here’s the percentage of students achieving a C grade or above, for each of the main exam boards.

	AQA	OCR (A)	OCR (B)	Edexcel
Further Maths	84.1%	91.49%	89.05%	88.6%
Physics	66.4%	70.25%	72.34%	71.8%
Chemistry	71.3%	69.5%	69.04%	74%
Average Total	73.93%	77.08%	76.91%	78.13%

What is the hardest A Level to study?

As we’ve seen, A Level Further Maths is widely regarded as the hardest A Level to study. 

Covering topics such as complex numbers, differential equations and matrices, Further Maths pushes students to the limits of their abilities and requires a deep understanding of advanced abstract concepts. 

The subject demands not only mathematical aptitude but also strong problem-solving skills and logical reasoning, making it a significant challenge.

Which is the hardest A Level exam board?

The perceived difficulty of A Level exams varies between exam boards, but there isn’t a definitive “hardest” exam board. 

The Department of Education sets the content exam boards cover at GCSE, AS Level and A Level. All exam boards in England are also overseen by Ofqual, ensuring fairness and consistency at A Level and GCSE – no matter which exam board you’re studying with.

However, while the difficulty is broadly the same, individual students will find different paper structures and question types pose unique challenges.

For example, OCR is often famed for its challenging Maths exams, while AQA is known for demanding assessments in subjects like Physics and Chemistry. 

On the other hand, AQA’s questions are generally seen as the most accessible for English Literature and English Language. Edexcel is recognised for its in-depth A Level humanities courses – with questions encouraging creative, independent thought.

Whatever exam board you’re studying with, familiarise yourself with mark schemes, past papers and specification for your subjects. Using these resources to guide your revision will help you feel prepared and confident when exams roll around.

Choosing your A Level Subjects: What to Consider

Are A Levels more stressful than GCSEs?

Although you’ll probably only study a maximum of four A Levels (compared to eight or more GCSEs), A Levels feature more content and more independent study than GCSEs. So yes, they can potentially be more stressful. 

The increased workload, higher expectations and pressure to perform for university applications all contribute to the stress of A Levels. The significance of A Levels in university admissions is a particular issue that undoubtedly intensifies the pressure on students during this crucial stage.

However, there are plenty of things you can do to reduce stress. Schedule plenty of study breaks, get outside and move your body (whether that’s a walk, jog or organised sports), eat well and prioritise sleep. If you’re struggling with stress, talk to a trusted teacher or academic coach. They’ll point you in the right direction and help you develop coping mechanisms.

How stressful is four A Levels?

As we’ve seen, A Levels can be stressful.

Most students take three A Levels. But there’s no limit here! Many ambitious students choose four (or more) subjects, giving breadth and flexibility when it comes to university applications.

There’s no doubt, taking four A Levels is demanding. You’ll have to jump between subjects and manage your time effectively, especially when it comes to revision and exams. But it doesn’t have to be stressful!

Before making your decision, think carefully about how you’d cope with an increased workload. Three As are way better than four Bs (it’s quality over quantity!), so evaluate your motivations, academic abilities and extracurricular commitments to make sure you can balance your workload and mental well-being.

What are the most respected A Levels?

Generally speaking, harder A Level subjects (like the ones we’ve listed above) are the most respected. So if you’re looking to impress, traditional subjects like Maths and Further Maths, the Sciences, History, Philosophy and English Literature are all great choices.

Subjects like Maths, Physics and Chemistry are particularly highly regarded due to their emphasis on critical thinking and problem-solving, as well as their relevance to a wide range of academic and professional fields. Additionally, subjects like English Literature, History and Philosophy are prized for their analytical and communication skills.

There’s a name for these subjects. They’re called “facilitating subjects” – the A Levels most required by Russell Group (and non-Russell Group) universities. Choosing one of these subjects will help keep your options open, giving access to a wide range of degree courses.

The eight facilitating subjects are:

• Biology
• Chemistry
• Physics
• Maths and Further Maths
• English Literature
• Geography
• History
• Modern and Classical Languages

Which three A Levels go well together?

This is a tricky one to answer, as it depends on your goals for university and career aspirations.

But in short, for students interested in STEM fields, Maths, Further Maths and a relevant science (Biology, Chemistry or Physics) can provide a strong foundation for careers in many different fields. Alternatively, for students interested in humanities or social sciences, a combination of English Literature, History and Politics can develop critical thinking, analytical, and research skills – essential for loads of creative degrees and professions.

Is Year 13 harder than university?

Year 13 can certainly feel challenging due to the pressure of impending exams and university applications. You’ve probably already transitioned to more self-led study and time-management in Year 12, but it’s still a lot. 

However, university will involve greater depth, specialisation, fully independent research and academic rigour – making a degree course (whether BA Hons, BSc Hons or anything else) more demanding. While you’re only studying one or two subjects at university (rather than three or four at A Level), you’ll take various modules at once. This means multiple essays and assignments across different topics.

The transition from A Levels to university can be a significant adjustment – but with an adaptable growth mindset, hard work and effective time management skills – you’ll flourish.
