Every "hardest A-Levels" list online is really an opinion in disguise. Here is an honest, evidence-aware view of which subjects demand the most — and why "what's the easiest?" is the wrong question to ask.
Quick answer: The A-Levels most often rated hardest are Further Maths, Physics, Chemistry, Maths, Biology and Modern Languages — they pair heavy content with high problem-solving or fluency demands. The ones usually called more accessible are essay or applied subjects like Sociology, Business, Media and Film. But difficulty is relative: the hardest subject is the one that fights your strengths, and universities care far more that your subjects fit your degree than where they sit on a difficulty list.

"What are the hardest A-Levels?" is the most-Googled A-Level question there is — and almost every answer is someone's opinion dressed up as fact. The honest version is more useful: certain subjects do place heavier demands on most students, but difficulty is genuinely personal, and choosing by a league table is how good students end up in the wrong subjects.
This ranking reflects how often each subject is rated hardest by teachers and students, and why. It is not an official list: no exam board ranks its subjects by difficulty.
| Rank | Subject | Why it is rated hard |
|---|---|---|
| 1 | Further Maths | Builds on A-Level Maths at speed, with abstract topics |
| 2 | Physics | Abstract ideas plus heavy maths in almost every question |
| 3 | Chemistry | Large content load across physical, organic and inorganic |
| 4 | Maths | Cumulative, so early gaps keep costing marks |
| 5 | Biology | Huge factual volume and precise mark-scheme language |
| 6 | Modern foreign languages | Fluency takes years and cannot be crammed |
| 7 | English Literature | Top grades need sharp essay craft under time pressure |
| 8 | History | Wide content plus sustained written argument |
| 9 | Economics | Diagrams, data analysis and evaluation in one paper |
| 10 | Computer Science | Programming, theory and logic tested together |
Across teachers, students and grade data, the same names recur at the demanding end:
What makes these demanding is a combination of content volume, abstraction, cumulative dependency and high-precision output — not any single factor.
Subjects often described as more accessible include Sociology, Business, Media Studies, Film Studies and Religious Studies. Two honest caveats: "more accessible" is not "easy" — every A-Level is a serious two-year qualification with real exams — and accessibility varies hugely by student. A confident writer may find Sociology comfortable and Chemistry brutal; a natural mathematician, the exact reverse.
Difficulty adds up when subjects overlap in demand. The combinations students most often find heaviest are:
These combinations are demanding but very achievable with secure foundations. For pairings by degree, see the best A-Level subject combinations.
National grade distributions are routinely quoted as proof that one subject is "harder" than another, but they are confounded: the students who take Further Maths are, on average, already very strong mathematicians, which skews the numbers. The only difficulty that matters for you is the fit between a subject's demands and your strengths and interests. A subject you find engaging is one you will work at — and effort, not innate "hardness", is what moves grades.
Here is the part students miss while hunting for the "easiest" A-Levels: universities value rigorous, relevant subjects. Maths, the sciences, English, History and languages keep the widest range of degrees open (the idea behind the Russell Group's Informed Choices guidance). Picking a lighter subject purely to chase a grade can quietly close the very degree you want — so weigh difficulty against where each subject leads. See best A-Level combinations for the course-by-course view.
Absolutely — difficulty is not destiny. Further Maths and the sciences produce thousands of A*s every year. With the right foundations, strong exam technique and targeted support on the topics that trip you up, a demanding subject is very winnable. The question is never "is this subject hard?" but "is it the right subject for me, and do I have the support to do it well?"
You will see tables claiming subject X has a lower A*–A rate than subject Y. Read them with care: each subject draws a different population. Further Maths posts high top-grade rates precisely because mostly strong mathematicians take it — not because it is "easy". Pass and top-grade statistics describe who sits a subject at least as much as the subject itself, which is why they are a poor guide to how hard a subject will be for you.
The hardest-rated subjects share specific features: cumulative dependency (Maths and the sciences punish early gaps), content volume (Biology, Chemistry, History), abstraction (Physics, Further Maths) and high-precision output under time pressure (essay subjects and languages). Identifying which of these a subject leans on tells you exactly how to prepare for it — and reassures you that the difficulty is specific and addressable, not mysterious.
A subject's "hardness" is not fixed — a great deal of it is how securely the foundations were taught. Students who struggle with A-Level Maths or Chemistry are very often carrying an unfixed gap from earlier work, not hitting a natural ceiling. Targeted teaching that repairs the foundation routinely turns a subject a student called "impossible" into a confident A.
