Choosing GCSE subjects or deciding which A levels to take can be one of the first significant academic decisions a young person makes, and it can feel stressful for both students and parents. Some subjects are widely considered more challenging than others because of their content, assessment style, workload and the skills they require. However, exam results alone do not tell us whether one subject is inherently harder than another.
So, which GCSE and A-Level subjects are considered the hardest, and what makes them challenging? This guide looks at common difficulty factors, exam demands and students’ experiences to help families make better-informed subject choices.
How Do We Define the Hardest GCSE and A-Level Subjects
There is no official list of the hardest GCSE or A-Level subjects. Difficulty can be measured in different ways, including pass rates, the proportion of students achieving top grades, syllabus size, assessment structure and the level of problem-solving or extended writing required.
Results data also needs to be interpreted carefully. Students taking different subjects can have very different levels of prior attainment and experience. For that reason, the subjects below should be viewed as subjects that many students find demanding rather than a definitive ranking of which qualifications are objectively the hardest.
Hardest GCSE Subjects in the UK
Some GCSE subjects are frequently described as challenging because they combine substantial content with demanding exam skills. Depending on the measure used, subjects commonly discussed include:
- Maths
- Art and Design
- English Language
- Citizenship Studies
- Geography
- Design and Technology
- History
- Psychology
- Business Studies
- English Literature
Some language GCSEs can show relatively high grade rates. However, comparisons should be treated carefully because students’ previous experience of a language can differ considerably between subjects. If your child is facing challenges in studying you can take support from GCSE tutors at Mixt Academy UK.

At A level, students often find subjects challenging when they involve a large syllabus, complex problem-solving, extensive independent study or demanding practical and written assessments. Subjects frequently regarded as demanding include:
- Computing
- Biology
- Physics
- Chemistry
- Law
- Maths
- Physical Education
- Psychology
- Design and Technology
- Other sciences
None of this means that students should avoid these subjects. A subject that feels challenging can still be an excellent choice when it matches a student’s interests, strengths and future plans. Good teaching, consistent practice and the right a level tutoring support can also make difficult topics much more manageable.
Why Do Some GCSE and A-Level Subjects Feel Harder Than Others
Several factors can make one subject feel more difficult than another. Some qualifications involve multiple forms of assessment, while others require students to combine knowledge, problem-solving, practical skills or extended writing. Different subjects also test very different skills. Modern languages may assess listening, speaking, reading and writing, while science subjects require students to understand scientific concepts, apply equations, interpret data and demonstrate knowledge of practical methods. Don’t imply that exam boards casually make one subject stricter than another.
Additionally, some topics may have large numbers of students performing well, so it feels competitive when setting marks, even if the topic itself is not actually a difficult one. Difficulty is also highly individual. One student may enjoy mathematical problem-solving but struggle with English literature essays, while another may experience exactly the opposite. Instead of assuming that a subject is inherently difficult, parents and teachers should look at the specific skills or topics an individual student is finding challenging.
Why Students Struggle With Some of the Hardest GCSE Subjects
In maths, students are often expected to apply familiar methods to unfamiliar problems rather than simply repeat a process they have memorised. Topics such as algebra, ratio, percentages and probability can feel difficult at first, but regular practice helps students recognise common problem types and choose the right methods more confidently.
Biology, chemistry and physics require students to remember substantial amounts of content while also understanding technical terminology, equations, practical methods and how to apply their knowledge in unfamiliar situations. Equations and abstract concepts in chemistry can be particularly difficult for students to understand at first. Breaking revision into smaller topics rather than trying to revise an entire subject at once can make the workload feel much more manageable.
In English, students must analyse texts and then explain their thinking to a sufficient level of detail to secure higher marks. Many students have a general comprehension of a text but have difficulty creating a well-developed paragraph. This is a skill that will develop with regular short analytical writing.
History involves remembering important dates, events and individuals, but success in the exam also depends on constructing clear, evidence-based arguments. Students who can explain why an event mattered, rather than simply describing what happened, are usually better placed to access the higher marks.

How Can Your Child Make Progress in a Difficult Subject
Struggling with a subject does not mean your child cannot improve. The right study habits, focused practice, and expert support can make difficult topics feel much more manageable.
Build Better Study Habits
Students improve through consistent practice rather than last-minute revision. Techniques such as flashcards, past papers, timed questions and self-quizzing can encourage active recall and exam practice. Reviewing mistakes is equally important because it helps students identify the areas that still need attention.
Identify the Real Gaps
Parents can start with simple questions such as, “Which part are you finding difficult?” This can help identify whether the problem is a particular topic, exam technique, confidence or something else. When a student is struggling to identify or overcome specific gaps, one-to-one support can provide additional explanation, structure and accountability.
Final Thoughts
Every ranking of the hardest subjects will look slightly different depending on how difficulty is measured, but the main message remains the same. Maths, the sciences, English and several other subjects can be particularly demanding because of their content, assessment structure and the range of skills students are expected to demonstrate.
Finding a subject difficult does not mean that a student is stuck. Progress often comes from small, consistent habits: focused revision, active practice, useful feedback and a clear understanding of what to work on next. A student moving from a grade 3 to a grade 4 has made meaningful progress, even if the subject still feels challenging.
With patience, effective study strategies and appropriate support, subjects that initially feel overwhelming can become far more manageable by exam day.
We Answer Every Question of Parents
Is maths really the hardest GCSE subject?
Maths is often described as one of the hardest GCSE subjects, but there is no official ranking that identifies a single hardest GCSE. Many students find maths challenging because it requires them to understand concepts, select appropriate methods and apply them to unfamiliar problems. Regular, focused practice can make these skills much more manageable over time. You can also find a tutor to increase the progress of your child.
Why is chemistry considered one of the hardest A-level subjects?
Chemistry combines theoretical concepts, calculations, equations and practical knowledge, so students need to develop several different skills at the same time.
Does a difficult subject mean my child will get a low grade?
No. A subject’s reputation for being difficult cannot predict an individual student’s result. Interest, prior knowledge, teaching, revision habits and exam technique can all influence performance. Consistent revision, exam practice and targeted support can help students make meaningful progress in subjects they previously found difficult.
Should my child avoid choosing a subject just because it is considered hard?
Not necessarily. A student’s interests, strengths, future study requirements and career plans are usually more useful considerations than a subject’s general reputation for difficulty. Students who enjoy a subject may also be more motivated to put in the consistent work required to improve.
How can a tutor help with a difficult GCSE or A Level subject?
A tutor at Mixt Academy UK can help identify where a student is struggling and focus lessons on those specific areas rather than relying on a general revision plan. This targeted, one-to-one approach can give students more focused opportunities to ask questions, practise difficult topics and receive individual feedback.
