Choosing A Level Subjects: What You Need to Know

A Level subjects play a crucial role in shaping a student’s academic journey and future career. Taken typically between the ages of 16 and 18, A Levels are advanced qualifications in the UK that allow students to specialise in subjects that interest them most. These subjects form the foundation for university applications and can significantly influence long-term career options.

Choosing the right A Level subjects isn’t just about picking favourites—it’s about aligning with your strengths, interests, and future goals. Whether you’re aiming for medicine, law, engineering, or the arts, your subject choices can open or limit opportunities down the line. That’s why understanding the structure and purpose of A Levels is essential before making any decisions.

In this blog, we’ll cover everything, from how many A Level subjects students typically take for university, to the best combinations for popular degree courses.

What Are A Level Subjects?

A Level subjects are advanced courses taken over two years, typically in Years 12 and 13 (Sixth Form). Designed to prepare students for university or specialised careers, A Levels allow you to dive deeper into subjects that align with your strengths and interests.

Most students choose three A Level subjects, although some opt for four if they are aiming for highly competitive university courses. Your school may offer guidance on how many subjects in A Level are manageable based on your academic record and goals.

There is a wide list of A Level subjects to choose from, including:

This flexibility means students can customise their A Level experience to match their academic direction—whether that’s science, humanities, or a mix of both.

A Level Subject Combination: Choosing the Right One

Before starting your A Levels, it’s important to understand the basic A Level requirements. Most schools and colleges ask for at least five GCSEs at grades 4–9, including English and Maths. Some A Level subjects may have their own specific requirements—for example, you may need a grade 6 or higher in GCSE Maths to take A Level Physics.

Once you’re eligible, the next step is to think carefully about your A Level subject combinations. Picking the right mix can influence your university course options and future career path. For example, combining Biology, Chemistry, and Maths is a strong choice for medicine, while History, Politics, and English can suit law.

While it’s great to follow your interests, it’s also smart to balance passion with practicality. Choose subjects you enjoy, but make sure they align with your long-term goals and the entry requirements for any careers or university degrees you’re considering.

A Level Subjects List (with Popular Categories)

There’s a wide list of A Level subjects to choose from, each offering a different set of skills and knowledge. To help you decide, it’s useful to look at subject categories and understand the A Level topics they typically cover.

Sciences
Subjects like Physics, Chemistry, and Biology are essential for science-based degrees. You’ll study topics such as atomic structure, genetics, and mechanics—ideal if you’re aiming for medicine, engineering, or natural sciences.

Humanities
History, Geography, and Politics encourage analytical thinking and essay writing. Expect to explore historical events, global systems, and political ideologies—useful for careers in law, journalism, or education.

Social Sciences
Psychology and Sociology focus on understanding human behaviour and society. These subjects involve research methods, theories, and real-world applications, making them popular choices among students.

Languages
A Levels in English Literature, French, Spanish, or other modern languages improve communication and analysis skills. You’ll study literature, culture, and language structure—valuable for international careers and creative fields.

Creative Arts
Subjects like Art, Drama, and Music let students express creativity. They involve practical work and coursework, offering a break from essay-heavy or calculation-based subjects.

Maths and Computing
Maths, Further Maths, and Computer Science are strong academic subjects. You’ll tackle algebra, algorithms, and statistics, which are key A Level topics for STEM-related careers.

This variety means there’s something for every student—whether you love solving equations, writing essays, or expressing yourself through performance.

Tip: A strong portfolio can boost your university application.

Matching your A Level subjects to your career ambitions helps ensure you’re on the right path and meet university course requirements. Always research what’s needed early so you can plan ahead.

Hardest and Easiest A Level Subjects

When choosing your A Level subjects, it’s important to understand the level of difficulty each subject may present. While it’s tempting to pick what seems like the easiest A Level subjects, remember that perceptions vary from student to student.

A Level Subject Difficulty Overview

Hardest A Level Subjects are often considered the most demanding due to complex content, heavy reading, and tough exams. For example, Further Maths has a steep learning curve and fast-paced lessons, while Chemistry requires both mathematical and scientific precision.

Meanwhile, Easiest A Level Subjects are often seen as more accessible due to a balance of coursework and exams, fewer mathematical demands, and a more narrative approach to content. However, “easiest” doesn’t mean “easy”—you still need consistent effort to do well.

Keep In Mind: Don’t choose a subject just because it sounds easy or hard. The best choice is one you enjoy and can succeed in. What’s challenging for one student may be the perfect fit for another.

Conclusion

Choosing your A Level subjects is one of the most important academic decisions you’ll make. It affects not just your next two years of study, but also your future university course options and career opportunities. Whether you’re aiming for A Level subjects for engineering, medicine, law, or computer science, making informed choices is key.

Be sure to check A Level requirements for the courses you’re interested in and explore different A Level subject combinations that suit your goals and interests. If you’re unsure whether to choose from the easiest A Level subjects or challenge yourself with the hardest A Level subjects, think about your strengths and long-term ambitions.
