A Levels Subjects Ranked by Difficulty: The Hardest Subjects in 2026

Moving from GCSEs to A Levels is arguably the biggest academic leap a student will face in the UK education system. It is no longer just about memory; it is about application, analysis, and managing a volume of content that can feel overwhelming.

The truth is, ranking A Levels by difficulty is subjective. A creative writer might find Physics impossible, while a mathematician might crumble under the weight of a History coursework essay. However, by analysing pass rates, the volume of content, and conceptual depth, we can identify the subjects that statistically trip students up the most.

Here is our definitive guide to A Level subjects ranked by difficulty for 2026.

At a Glance: The Top 10 Hardest A Levels

Before we dive into the details, let’s just look at a list of the top subjects consistently voted the most challenging by students and tutors alike.

Rank	Subject	Why it’s so hard?
1	Further Mathematics	Abstract concepts that bridge the gap to university-level maths.
2	Physics	Heavy reliance on high-level maths and abstract theory.
3	Chemistry	Massive volume of content and memorisation required.
4	Modern Foreign Languages	You are often competing against native speakers.
5	Biology	The "easy science" trap; extraordinarily specific mark schemes.
6	Computer Science	High failure rate in coursework (NEA).
7	History	Critical analysis required; heavy reading load.
8	English Literature	Subjective marking makes the A* elusive.
9	Psychology	Scientific approach to essay writing; extensive terminology.
10	Music	Requires performance, composition, and theoretical mastery.

The Top 5 Hardest A Level Subjects Ranked

When we look at hardest A Level subjects ranked by conceptual difficulty, the STEM subjects invariably dominate. These courses require a way of thinking that cannot simply be memorised.

1. Further Mathematics

Further Maths is widely considered the boss level of Sixth Form. It introduces topics like Complex Numbers, Matrices, and Hyperbolic Functions—concepts that standard A Level Maths doesn't touch.

• The Data Paradox: You might see data showing a high percentage of A* grades in Further Maths and think it looks easy. Do not be fooled. This subject is usually only taken by the top 1% of mathematicians who are already predicted an A* in standard Maths. The barrier to entry is what makes it #1.

2. Physics

Physics is the ultimate test of applying logic to the physical world. It isn't enough to know the formula; you must know which iteration of the formula applies to a changing scenario.

• The Struggle: The maths content is significant. If you aren't taking A Level Maths alongside Physics, you are statistically much less likely to achieve a top grade.

3. Chemistry

A Level Chemistry difficulty comes from two angles: the sheer volume of content and the complexity of the concepts. Topics like Organic Synthesis and Thermodynamics require you to link disparate ideas together constantly.

• Student Verdict: It is often voted the most demanding science because there is nowhere to hide. You either know the reaction mechanism, or you don't.

4. Biology

Many students fall into the trap of thinking Biology is the "easy science."

• The Reality of A Level Biology Difficulty: Biology has a massive vocabulary requirement—essentially learning a new language. However, the real killer is the mark scheme. You can understand a biological process perfectly, but if you don't use the exact keyword on the examiner's list (e.g., saying "cell membrane" instead of "plasma membrane"), you lose the mark.

5. Computer Science

Computer Science frequently has one of the lowest pass rates in the UK. Why? The Non-Exam Assessment (NEA). This coursework project is a massive time-sink that requires building complex software from scratch. Many students underestimate the hours needed to debug their code, leading to a scramble at the finish line.

The "Silent Killers": Deceptively Hard Humanities

When discussing all A Level subjects ranked by difficulty, we cannot ignore the humanities. These subjects are often easier to pass but much harder to master at an A* level.

English Literature

In Maths, 2+2=4. In English, the answer depends on your ability to argue a nuanced perspective. Ranking A Levels by difficulty often puts English lower on "fail" lists, but highest on "frustration" lists. The subjectivity of the marking means that achieving an A* requires sophisticated, unique arguments that stand out to a weary examiner.

History

History is a marathon, not a sprint. It combines the need for rote memorisation (dates, names, acts of parliament) with high-level critical analysis. You cannot just regurgitate facts; you must evaluate their significance in a structured essay under timed conditions.

Factors That Determine A Level Difficulty

When looking at an A Level difficulty ranking, it is helpful to understand why a subject is hard so you can play to your strengths.

1. Conceptual Abstractness: Subjects like Further Maths and Physics require you to grasp invisible, theoretical concepts.

2. Content Volume: History, Biology, and Psychology are "heavy" subjects. The difficulty lies in organising and retaining thousands of facts.

3. The "Facilitating" Factor: The hardest subjects are often "Facilitating Subjects"—those preferred by Russell Group universities (like Oxford and Cambridge). They are designed to be rigorous to prepare you for degree-level work.

How to Study for A Levels: Tips for The Hardest Subjects

So, you have chosen the hard subjects. How do you survive them? Here is how to study for A Levels without burning out.

1. General Tips for A Level Revision

• Active Recall is King: Stop re-reading your textbooks. It feels like work, but it’s passive. Instead, close the book and write down everything you remember about a topic.

• The "Blurting" Method: This is one of the best tips for A Level revision. Pick a topic, set a timer for 5 minutes, and scribble every keyword, formula, and fact you know. Then, check your notes and write what you missed in a different colour.

2. Subject-Specific Revision Guides

• How to Revise Business Studies A Level:Business is about application. Do not just learn the definition of "economies of scale." Learn a case study of a company that achieved it (like Amazon) and apply it to the exam context. Focus on AO2 (Application) and AO3 (Analysis) marks.

• How to Revise for Media Studies A Level:This subject is theory-heavy. Create "Theory Cards" for key critics (e.g., hooks, Van Zoonen, Gilroy). You need to be able to apply their frameworks to unseen media texts, not just the ones you studied in class.

• How to Get an A in A Level Religious Studies:Structure is everything. For your essays, learn the specific structure your exam board wants (often PEEL: Point, Evidence, Explanation, Link). You gain marks for the logical flow of your argument, not just your knowledge of religious scripture.

The Golden Rule: Time Management

A common question we get is: "How many hours to study a day for A Levels?"

There is no magic number, but for top grades, we recommend 4–5 hours of independent study per subject, per week (outside of lessons).

• Year 12: Build the habits. 2 hours a night total.

• Year 13: Ramp it up. 3–4 hours a night total.

Conclusion

Ultimately, A Levels ranked by difficulty is a guide, not a rule. The "hardest" subject is the one you enjoy the least. If you love Physics, the hours of problem-solving will feel like a challenge rather than a chore. If you hate reading, English Literature will be torture.

At Oxford Global Courses, we believe any student can master these subjects with the right support. Don't shy away from the hard subjects—they are often the most rewarding and the most respected by universities.

Frequently Asked Questions (FAQ)

1. What is statistically the #1 hardest A Level subject?

Further Mathematics consistently ranks as the hardest due to its abstract conceptual nature and the fact that it assumes you have already mastered standard A Level Maths content.

2. Which A Level has the lowest pass rate?

Computer Science and Physics frequently record some of the lowest pass rates in the UK (often around 95-96%, compared to 99% for Art), due to the combination of difficult theory and coursework pitfalls.

3. How long should I study for A Levels daily?

To achieve A/A* grades, most successful students aim for 3–5 hours of independent study per day (including free periods at school), split across their three subjects.

4. Is A Level Biology harder than Chemistry?

Chemistry is generally considered conceptually harder (more maths and abstract processes), while Biology is harder in terms of volume and the strictness of the mark schemes.

5. What are the easiest A Level subjects to pass?

Subjects like Sociology, Media Studies, and Film Studies often have higher pass rates (A*-E), though achieving the top A* grade still requires significant critical analysis and effort.
