Top 20 Hardest A Level Subjects
1. Further Maths
Further Maths routinely ranks as the most complex A Level subject due to its challenging content. This course requires students to master advanced mathematical concepts alongside difficult problem-solving and logical reasoning. Only those with a genuine passion for mathematics typically pursue this subject, and they must be prepared to invest considerable time and effort in their studies.
The grading profile in Further Maths is unique: while a sizeable proportion of students achieve either A or A*, this is because only high-performing, mathematically able students typically enrol. This selectivity creates a cohort where the academic bar is already very high, reinforcing the subject’s reputation for rigour.
What distinguishes Further Maths is its in-depth exploration of advanced areas, often including modules such as Pure Mathematics, Mechanics, Statistics, and Discrete Mathematics. It’s not just an add-on to the standard Maths A Level; rather, it extends foundational topics to a much greater depth. This subject is especially valued for university courses in maths, physics, and engineering, where a strong mathematical foundation is essential.
2. Maths
Mathematics remains the most popular A Level subject, surpassing English Literature in enrolment. Yet, its widespread popularity does not mean it is easy. There is a substantial leap in difficulty from GCSE Mathematics, as A Level Mathematics requires students to develop highly logical thinking and complex problem-solving skills.
The course structure encompasses three main disciplines:
- Pure Mathematics
- Mechanics
- Statistics
Success in all three is essential, presenting a significant challenge, especially for students who may excel only in one area. In mechanics, the introduction of physics concepts can introduce additional content that some students find daunting.
The pace and level of abstraction in A Level Maths mean students are often pushed out of their comfort zones quickly. The second year, in particular, demands mastery of more advanced theory and nuanced applications, which can be a significant hurdle. Nevertheless, strong mathematical skills open doors to a range of careers in science, business, and technology.
3. Chemistry
Chemistry holds a place among the most demanding A Level subjects due to both content volume and depth. Not only does it require a firm grasp of theoretical and often abstract concepts, but students must also learn to apply knowledge practically in laboratory contexts.
Many find the transition from GCSE to A Level Chemistry steep, with topics such as organic chemistry, periodicity, and advanced principles like enthalpy and electron structure making up the core of the curriculum. The workload is heavy, with independent study often essential to grasp complex concepts, especially before practical sessions.
Despite its rigour, Chemistry offers substantial value for those with future aspirations in medicine, natural sciences, or engineering. The high pass rate reflects the dedication of students who accept the subject’s challenge and the significant personal discipline required to succeed.
4. Physics
Physics ranks among the toughest A Levels due to its abstract and mathematically demanding content. The subject encompasses complex topics such as nuclear and particle physics, thermodynamics, and oscillations, all of which require strong problem-solving skills alongside a solid understanding of mathematics. Students often pair Physics with Maths or Further Maths to effectively handle the mathematical aspects.
The content moves beyond theory to real-world applications and experimental work, so an aptitude for practical investigations is also crucial. Physics challenges students to think critically about the laws governing the natural world, making it an intellectually demanding yet enriching experience for those interested in understanding how things work at a fundamental level.
Despite its difficulty and relatively low uptake compared to other subjects, Physics remains essential for careers in engineering, physical sciences, and technology. The subject fosters analytical thinking and precision, rewarding diligent students with a broad scientific understanding.
5. English Literature
English Literature is unique among the hardest A Levels because its challenges lie not in formulas or facts, but in critical thinking, creativity, and original analysis. Students must engage deeply with a wide range of texts while learning to develop independent interpretations that impress examiners.
Unlike many science or maths subjects, English Literature does not have a straightforward formula for success. The depth of analysis required means students must read extensively and develop sophisticated written communication skills. The ability to think creatively and critically is essential to stand out.
Additionally, the coursework and exam essays demand coherent argumentation and a strong vocabulary, which can be daunting for those who find extended writing or abstract thinking difficult. This subject is prized for developing skills in analysis and expression, useful across a variety of academic disciplines and careers.
6. History
History’s reputation as a hard A Level stems from the sheer volume of knowledge required and the deeper analytical skills needed compared to GCSE. Students must memorise extensive factual content while understanding the causes and implications of significant historical events.
The course typically covers wide-ranging topics, from Italian Unification to Russian history, and requires students to engage with both factual recall and evaluative essays. The need to analyse historical arguments and interpret evidence critically adds layers of complexity.
Moreover, success in History hinges on strong essay-writing skills and the ability to organise large amounts of information coherently. Mastery of this subject demonstrates research skills and critical thinking, both of which are valued in higher education and beyond.
7. Biology
Biology is known for its extensive syllabus and the considerable leap in complexity from the GCSE level. Students are faced with a vast array of subjects to master, including everything from cell structure to genetics and biochemistry. This breadth requires not only memorisation but also deep analytical skills.
A significant challenge in Biology is the expectation to apply theoretical concepts to practical contexts, particularly during lab work and analytical assessments. The level of independent study required means students must actively consolidate and extend classroom learning, often working through complex textbooks and research materials.
For those passionate about understanding life and the natural world, Biology is an invaluable subject. However, the necessity to handle detailed information, analyse data, and connect ideas across different biological systems means consistent effort is vital for success.
8. Computer Science
Computer Science demands a combination of theoretical understanding and practical programming skills. The curriculum encompasses programming languages, algorithms, and problem-solving, alongside theoretical topics such as computational thinking and computer architecture.
One of the most challenging aspects is the non-examined practical project, where students must design and develop a software solution to a real problem. This project tests their ability to manage a substantial piece of independent work and document their processes thoroughly.
Additionally, Computer Science is less hands-on than some students expect, often focusing more on theory than dismantling physical computers. Success here requires not only technical proficiency but also logical reasoning and dedication to keeping up with rapidly evolving concepts in technology.
9. Modern Foreign Languages
Modern Foreign Languages (such as French, German, or Spanish) are challenging due to their demand for spoken fluency, advanced comprehension, and a deep understanding of grammar and vocabulary. In addition to acquiring language skills, students often study literary texts and delve into the historical and cultural contexts of the countries where the language is spoken.
Mastering all aspects like reading, writing, listening, and speaking requires robust revision strategies, especially as exams test each skill in different formats. Oral exams can be especially gruelling, demanding both linguistic accuracy and quick thinking under pressure.
Despite these challenges, Modern Foreign Languages equip students with valuable communication skills. The rewards include cultural literacy and improved career prospects, particularly for those interested in travel, diplomacy, or international business.
10. Psychology
Psychology A Level is deceptively challenging, with a curriculum that merges scientific principles with essay-based assignments. The subject demands a high retention of studies and their findings, as these must be applied in exam contexts to construct thorough arguments about human behaviour and cognition.
A notable difficulty lies in the dual requirement for scientific thinking and proficient essay writing. Students need to be comfortable with both evaluating experimental data and expressing their understanding in clear, concise written formats, often under time constraints. This straddling of two skill sets can be daunting for those whose strengths aren’t evenly split.
In addition, Psychology’s popularity belies its rigorous nature. Many students are surprised by the breadth of content and the rapid pace of learning required to keep up. The subject is highly valuable for those interested in the sciences or humanities, as it opens doors to diverse career paths in health, research, or education.
11. English Language
Unlike its counterpart, English Literature, English Language A Level steers away from classical texts to focus on the complexities of linguistic theory and analysis. Students explore how language is constructed, why it evolves, and the socio-cultural forces that shape communication.
This subject stands out for how quickly it diverges from the more familiar territory of GCSE English. Learners must engage with new linguistic concepts and terminology such as syntax and phonology, while critically examining everyday spoken and written language. High-level analytical skills are essential for success.
Furthermore, top grades are tough to obtain in English Language, with very few students achieving an A* in recent years. It is a highly analytical and technical course, best suited for those who are curious about language and comfortable with both detail and theory.
12. Economics
Economics challenges students with its dual focus on quantitative analysis and extended written arguments. The subject covers a broad syllabus, encompassing both macroeconomic concepts such as government policy and inflation, and microeconomic topics, like business structures and consumer behaviour.
Mastery requires significant skill in essay writing, critical analysis, and the application of mathematical principles to real-world situations. Many students struggle with the mathematical aspect, particularly interpreting graphs and applying formulas to predict economic outcomes.
Due to the interdisciplinary nature and broad content, Economics is a strong foundation for careers in finance, business, and public policy. However, its demands require students to be adept in both numerical reasoning and extended critical writing.
13. Law
Law A Level is regarded as a rigorous subject, often chosen by those interested in pursuing a legal career, though it is by no means an easy route. The curriculum is comprehensive, covering key legal principles, case law, and the workings of legal systems in the UK and internationally. Success in Law requires strong analytical skills and the ability to interpret and apply legal reasoning to unfamiliar scenarios.
A particular challenge of the Law is the extensive memorisation required. Students must recall landmark cases, legal precedents, and statutory provisions, demonstrating their ability to evaluate, argue, and reach sound judgments. The exams require well-structured, persuasive writing and the ability to analyze theoretical problems from multiple perspectives.
Despite its demanding nature and relatively low numbers of students taking the subject, Law remains a solid preparatory choice for university law degrees and other analytical professions. Those who excel in debate, critical analysis, and structured writing tend to thrive.
14. Business Studies
Business Studies at A Level is sometimes considered more accessible than its close relation, Economics, but it is by no means an easy ride. The content delves deeply into business strategy, marketing, operations, and human resource management, alongside case analysis and numerical skills for financial performance. Students must digest a big syllabus, retain a raft of business terms and models, and use them fluently in exams.
Much of the challenge lies in the breadth of content and the demand to transition between different question types, ranging from concise factual answers to extended analytical essays. Success requires the ability to interpret data, apply logical reasoning, and construct well-supported arguments in varying formats.
Ultimately, Business Studies equips students with a strong awareness of how organisations function and a toolkit of transferable skills for further study or careers in business and management.
15. Design & Technology (Product Design)
Design & Technology, especially in Product Design, is a challenging A-Level subject that has seen a significant decline in entrants due to its complexity. This subject combines creativity with analytical and technical skills, enabling students to create innovative products, analyze existing designs, and understand manufacturing processes.
Key areas include product analysis, innovation, prototyping, and evaluation, culminating in a major coursework project that can be time-intensive. Many students underestimate the independent study and practical work involved, often struggling with balancing creative design with the demands of technical understanding and scientific application.
Those with a genuine passion for design thinking and practical creation find it rewarding; however, the depth and time commitment required make it one of the most challenging A Levels for those less dedicated or prepared.
16. Art
Art A Level is frequently underestimated, yet it consistently ranks among the most demanding subjects due to the extensive commitment required in both creative and academic skills. Students not only need to produce original artworks to a high standard but are also expected to submit an analytical ‘Personal Study’ essay, integrating critical analysis and research. Success hinges on the ability to convey personal ideas clearly while supporting them with contextual understanding.
The time commitment for Art is considerable, perhaps unmatched by other A Level subjects. Coursework is intensive, and students often spend long hours outside lessons developing their portfolios and refining techniques. This pressure can be overwhelming, particularly for those juggling Art with other challenging subjects, and effective time management becomes essential.
Despite the rigour, Art A Level can be greatly rewarding for those passionate about creative pursuits. Graduates emerge with a robust set of skills, including visual analysis, project management, and critical writing, making them well-prepared for university applications in creative fields.
17. Media Studies
Media Studies might appear less demanding at first glance, but its combination of theoretical analysis and practical production skills makes it challenging. The curriculum covers critical aspects such as analysing media texts, understanding audience theory, and exploring the impact of media on society. Practical work often includes creating original media products, which tests a student’s technical and creative abilities.
Another key challenge is the variety of assessment formats. Success depends on adapting to various types of questions, ranging from analytical essays to interpreting case studies and creating innovative content. High-achieving students must handle tasks swiftly and thoughtfully, integrating complex theory with their practical outputs in a way that demonstrates their understanding.
Ultimately, Media Studies is suited for those interested in communication, film, or television production. Its academic demands, coupled with the need for creativity and technical skills, place it firmly among the more challenging A Level options.
18. Sociology
Sociology explores the complexities of human society, investigating topics such as social structures, institutions, and cultural norms. The subject’s difficulty stems from the breadth of its content: students cover diverse topics, including crime, education, and family, all of which require critical analysis and evaluation of sociological theories and studies.
A further challenge is the requirement for essay-based assessments. Students must craft coherent arguments, apply theoretical knowledge to real-world scenarios, and critically assess research methodologies. Memorising case studies and sociological perspectives is vital for strong exam performance.
Sociology, while intellectually demanding, provides valuable insights into social behavior, making it a helpful field for careers in human resources, social work, or marketing. Its combination of memorization, analytical reasoning, and structured writing skills cements its place among the most challenging A-Level subjects.
19. P.E. (Physical Education)
Physical Education (P.E.) at A Level is far more rigorous than many assume, especially for those expecting it to be an ‘easy’ choice. Unlike its GCSE counterpart, the course requires specialisation in a single sport, as well as a comprehensive study of the human body’s anatomy, physiology, and biomechanics. This introduces a scientific aspect that surprises many students.
The curriculum blends practical skills with theoretical understanding. Students must analyse performance, apply scientific concepts to sporting scenarios, and demonstrate an awareness of psychological factors that affect athletes. The volume of technical vocabulary and depth of understanding required make this course particularly challenging.
Successfully tackling P.E. means balancing hands-on assessment with extensive written coursework and exams. Those who manage this demonstrate not just skill in sport but also strong abilities in critical thinking and scientific reasoning, making it a substantial academic challenge.
20. Fine Art
Fine Art, similar to other creative subjects, is often underestimated in its level of difficulty. The subject requires a fusion of artistic talent, critical thinking, and academic discipline. Students must produce a body of creative work, alongside written components, that demonstrates both technical ability and theoretical understanding.
There is a marked intensity to the coursework, with sustained independent projects and a substantial requirement for research and personal reflection. Fine Art students are also expected to respond to feedback and continually evolve their practice, all while managing tight deadlines.
Moreover, Fine Art attracts a diverse cohort of students. Still, success often hinges on the ability to commit vast amounts of time to their work and to develop both creative and analytical skills. The outcome is a challenging yet rewarding A Level that prepares students for creative disciplines at university or in professional practice.

What are the Hardest A Level Exam Boards?
In the UK, the three main exam boards for A Levels are Pearson Edexcel, AQA, and OCR. There’s no definitive answer to which board is the hardest, as difficulty often depends on individual perception. Universities don’t favour one board over another, so your choice usually comes down to what your school offers and what your teachers are familiar with. It’s important to know that all boards maintain comparable standards. This is ensured by the UK regulator, Ofqual, which maintains consistent quality and difficulty levels across Edexcel, AQA, and OCR.
Schools may select different boards for specific subjects based on teacher expertise or the style that best suits their students.Choosing your A Level subjects is a significant decision. These choices influence your university options and vary widely in difficulty. Some students thrive on the challenge of tougher A Levels, which require a considerable amount of independent study and a deep understanding. Remember, the jump from GCSE to A Level is substantial. Instead of juggling many subjects, you focus on fewer but in greater depth.
There’s also a notable gap between subjects. For example, A Level Physics builds heavily on GCSE, introducing more complex ideas, while Theatre Studies focuses on in-depth exploration rather than technical difficulty. It’s also wise to consider how certain subject combinations might affect your university choices. For tailored guidance and support in navigating these challenges, platforms like Udemy can be a valuable resource, offering learning materials designed to match your learning style and help you make informed decisions.
