The Hardest A-Level Subjects Ranked

Which A-level really tests you the hardest? Ask ten people and you'll get ten different answers, because "hardest" can mean the toughest syllabus, the lowest pass rate, or the subject with the smallest share of students reaching an A*.

‍

We've built a ranking that weighs all of this together: 2026 JCQ grade data alongside a survey of teachers and lecturers. Further Maths, Physics, and Chemistry come out on top as the three hardest A-levels overall.

‍

In this guide, we'll rank the top ten hardest A-levels, explain what the data shows, and unpack why a high top-grade rate and true difficulty aren't the same thing.

‍

Let's get straight into the ranking.

Key takeaways

• Further Maths, Physics, and Chemistry rank as the three hardest A-levels overall for 2026, based on 2026 JCQ grade data combined with a 2025 survey of 200 teachers and university lecturers conducted by TutorChase.
• Pass rate and difficulty aren't the same thing, and Further Maths proves it: it has a 98.2% pass rate and a 28.7% A* rate, among the highest on this list, yet still tops our ranking as the hardest A-level, because only students already excelling at Maths tend to choose it.
• Computer Science has the lowest A*-E pass rate of any major A-level, at 95.4% in 2026, below the UK all-subject average of roughly 97.5%, though this measures fail rate, not syllabus difficulty.
• The full top 10 ranking, in order: Further Maths, Physics, Chemistry, Biology, Modern Foreign Languages, Economics, Computer Science, English Literature, History, Geography.
• Drama & Theatre, Art & Design, Media Studies, and German have the highest pass rates in 2026, each above 99%, sitting at the opposite end of the difficulty scale.
• Whether to take a hard A-level depends on relevance, not prestige. Universities generally value subjects that align with your intended degree over difficulty alone, so weigh grade risk against your actual goals before choosing.

How we're ranking the hardest A-levels

We've ranked these subjects using two sources: real 2026 grade data from JCQ, and a 2025 survey of 200 teachers and university lecturers conducted by TutorChase on which A-levels they consider the most demanding.

‍

These two measures don't always agree. A low pass rate doesn't automatically mean a subject is harder. It often means fewer students who take it were fully prepared, while a high pass rate can simply reflect a self-selecting cohort of strong students.

‍

That's why Further Maths tops this ranking despite a strong pass rate. We'll unpack exactly why this happens in the next sections.

The top 10 hardest A-levels, ranked

Based on the same blend of 2026 JCQ grade data and the TutorChase teacher and lecturer survey, some subjects consistently stand out for their content depth, cognitive demand, and unforgiving assessment style.

‍

Here are the ten A-levels that come out on top.

1. Further Mathematics

• Entries (2026): 21,032
• A* rate: 28.7%
• Pass rate (A*-E): 98.2%

Further Maths tops this ranking despite that high pass rate, because students who take it are typically a particularly mathematically strong, self-selecting cohort.  Strip away that self-selection, and the content itself is genuinely demanding: differential equations, complex numbers, and matrices sit alongside advanced calculus, all covered in the same two years as every other A-level.

‍

That combination of dense content and a self-selected cohort is exactly why Further Maths resists a simple label. For the full picture on this one, see our guide to how hard Further Maths A-level really is. 

2. Physics

• Entries (2026): 45,800
• A* rate: 11.4%
• Pass rate (A*-E): 95.6%

Few subjects ask you to unravel the secrets of the universe quite like Physics, tackling the same questions that occupied Newton and Einstein. That curiosity comes at a cost: the subject demands substantial mathematical confidence, particularly in algebra, trigonometry, graphs, and quantitative problem-solving, applied fluently rather than simply learned. 

3. Chemistry

• Entries (2026): 65,541
• A* rate: 9.2%
• Pass rate (A*-E): 95.9%

Three genuinely distinct disciplines sit inside this one A-level: organic, inorganic, and physical chemistry, each demanding a different skill set. Success in Chemistry requires heavy content recall alongside quantitative problem-solving, so strong memory alone isn't enough, a combination reflected in a 9.2% A* rate despite being one of the most widely taken sciences.

‍

Knowing which of the three disciplines plays to your strengths makes a real difference here. See our A-level Chemistry syllabus breakdown for the full topic-by-topic detail. 

4. Biology

• Entries (2026): 73,925
• A* rate: 9.0%
• Pass rate (A*-E): 96.0%

The four-letter genetic code shared by every living thing on Earth is just one small piece of a subject spanning genetics, ecology, and physiology, all packed into a single two-year course. That content-heavy breadth is then tested through exams demanding you apply it to unfamiliar experimental data, not simply recall it. 

5. Modern Foreign Languages

• French entries (2026): 6,888 | A*: 11.3% | Pass rate: 98.8%
• Spanish entries (2026): 8,434 | A*: 10.3% | Pass rate: 99.0%
• German entries (2026): 2,294 | A*: 15.7% | Pass rate: 99.3%

Language A-levels demand near-native fluency built from scratch within a fixed number of teaching hours. In a 2019 review of grading standards across six subjects, Ofqual found that French, German, and Spanish were graded more severely than the other subjects in that comparison, and chose not to adjust the grades as a result. 

6. Economics

• Entries (2026): 47,157
• A* rate: 7.6%
• Pass rate (A*-E): 98.2%

Economics asks you to apply clean theoretical models, supply and demand, rational choice, to messy, unfamiliar real-world scenarios, then argue where the model breaks down. That chain of reasoning, interpreting data, applying theory, and evaluating its limits, all under timed exam pressure, is where the subject earns its difficulty. 

7. Computer Science

• Entries (2026): 20,009
• A* rate: 6.3%
• Pass rate (A*-E): 95.4%

Computer Science's challenges don't end at A-level. According to a UK STEM education briefing, university Computer Science degrees report a dropout rate of roughly 9.8%, among the highest of any UK degree course. That pattern starts early, since the subject demands both abstract logical reasoning and precise, error-free coding, a combination that's unforgiving of half-understood concepts.

8. English Literature

• Entries (2026): 36,196
• A* rate: 9.5%
• Pass rate (A*-E): 99.3%

Since the 2015 reforms, most A-level English Literature papers have moved to closed-book assessment, meaning the set texts you've studied all year aren't allowed in the exam room. Every quotation has to come from memory, on demand, under timed pressure, turning literary analysis into a genuine feat of recall as much as interpretation.

9. History

• Entries (2026): 46,960
• A* rate: 5.9%
• Pass rate (A*-E): 99.0%

AQA's specification alone requires students to cover a chronological range of at least 200 years, with a single Breadth Study paper often spanning a century on its own, think Russia 1855–1964 or America 1865–1975. Holding that much political, social, and economic change together in one argument, rather than studying isolated events, is what separates a strong essay from a thin one.

10. Geography

• Entries (2026): 34,128
• A* rate: 5.8%
• Pass rate (A*-E): 98.5%

Geography is one of the few A-levels that runs two separate academic disciplines side by side: physical geography, tested like a science with systems and data, and human geography, argued like an essay-based social science. Edexcel's own exam structure makes this explicit, splitting Paper 1 and Paper 2 between the two, then combining both in a synoptic final paper.

Why top-grade rate isn't the same as difficulty

Further Maths has one of the highest A* rates on this list, at 28.7%, yet it topped our ranking as the hardest A-level. That isn't a contradiction. It's a result of who chooses to take it.

‍

Only students already excelling at standard Maths tend to pick Further Maths in the first place, so the cohort walks in stronger than average before a single lesson happens. A subject with a broader, less self-selected intake will naturally show a lower A* rate, even if its content is less demanding.

‍

That's why a high top-grade rate alone can mislead you. Top-grade rates reflect both the assessment and the characteristics of the students taking the subject, not difficulty on their own.

‍

Which A-level has the lowest pass rate?

Computer Science has the lowest A*-E pass rate of any major A-level, at 95.4% in 2026. 

‍

That's below the UK all-subject average of roughly 97.5%, and worth separating clearly from "hardest by content": a low pass rate reflects how many students struggle to reach a bare pass, not how demanding the syllabus is, which is why Computer Science doesn't top our difficulty ranking despite this statistic.

The easiest A-levels (for comparison)

Now that you know which A-levels top the difficulty ranking, you might be just as curious about the subjects sitting at the opposite end.

‍

Here are the A-levels with the highest A*-E pass rates in 2026:

• Drama & Theatre: 99.8%
• Art & Design (Fine Art): 99.7%
• Media Studies: 99.4%
• German: 99.3%

Should you avoid a hard A-level?

No, not automatically, but you should weigh grade risk against how much the subject serves your future plans. A hard A-level makes sense if it's required or preferred for your target degree, since universities value relevant subjects over an easier grade elsewhere. It makes less sense if you're choosing it purely for prestige.

‍

The safest way to judge this is to speak with a teacher who knows your current strengths, rather than relying on a general ranking alone.

‍

Choosing the right subject is only half the decision, though, since how many you take alongside it matters just as much. Our guide on how many A-levels you should take walks through exactly how to strike that balance.

Should I avoid hard A-levels to protect my grades?

Not automatically. Weigh the grade risk against how relevant the subject is to your future degree or career before deciding.

Do universities prefer harder A-levels?

Universities generally value subjects relevant to your intended course more than difficulty alone. Check the required and preferred subjects published for your specific course, and use those directly rather than relying on a hardest-subject ranking like this one when choosing. 

Conclusion: What "hardest" really means for your A-levels

There's no single, universal answer to which subject deserves the top spot, since difficulty depends on what you measure and who's taking the exam.

‍

That said, Further Maths, Physics, and Chemistry consistently rank among the hardest A-levels by content and reputation, even where their pass rates suggest otherwise.

‍

That distinction matters more than the ranking itself: choosing a subject that fits your goals and strengths will always serve you better than chasing a position on a table.
