Why are your A Level subject choices so important?

If you’ve already decided the field you want to pursue, then choosing the right A Level subjects can help you build the foundational skills you need for that career. Subjects like Mathematics and Physics allow you to develop problem-solving and analytical skills, while Chemistry and Biology teach you scientific thinking, and Literature and History teach you how to think critically and communicate your ideas.
Moreover, universities may consider your A Level subjects alongside your grades and wider application when assessing whether you meet the academic preparation expected for a particular course.

A Level subject choices for Medicine

Pursuing a degree in Medicine requires a rigorous academic foundation, as medical schools have strict entry criteria. Choosing the right A Level subject combination ensures you meet university prerequisites and prepare for the demands of medical training.
Chemistry is a common prerequisite for Medicine and is required by many medical schools, although exact subject requirements vary by country and university. It provides the essential understanding of biochemistry, organic reaction mechanisms, and pharmacology required in medical education.
Biology is required or recommended by many medical schools. It covers human anatomy, cellular processes, genetics, and physiology, laying a direct foundation for clinical studies.
To round out your A Level subjects, you can choose Maths, Physics, Psychology, or other humanities.
Mathematics is a respected subject choice, and demonstrates high quantitative capability, logic, and data handling skills needed in medical research and statistics. Physics helps build problem-solving skills. Subjects like Psychology or Literature offer breadth, highlighting strong written communication, critical analysis, and understanding of human behavior.

So, your subject combinations could look something like this:

  • Option 1: Chemistry, Biology, Mathematics, Physics
  • Option 2: Chemistry, Biology, Mathematics, Psychology 
Also, keep in mind that strong subject choices alone aren’t enough to secure your spot at top institutes. Academic success is also critical, as universities typically require top-tier grades (A* / A) across science subjects. Alongside A Level performance, some medical schools also require or use admissions tests such as the UCAT. Test requirements vary by university and country, so check the admissions process for each medical school you are considering.

A Level subject choices for Engineering

Pursuing a degree in Engineering requires a strong foundation in physical sciences and quantitative analysis. Because engineering encompasses a wide range of disciplines—such as Mechanical, Civil, Chemical, Electrical, Bioengineering, Aerospace, and Software Engineering, subject requirements and recommendations can vary depending on your specific field of focus.
Mathematics is a core requirement for many engineering degrees and is particularly important for programmes involving substantial quantitative analysis. It forms the backbone of engineering analysis, providing the tools needed for differential equations, calculus, linear algebra, and vector mechanics.
Physics is required or strongly recommended for many engineering degrees, particularly disciplines such as mechanical, electrical, civil and aerospace engineering. It introduces critical concepts such as classical mechanics, thermodynamics, electromagnetism, and material science.
Chemistry may be particularly useful for specialized disciplines such as Chemical Engineering, Materials Science, Environmental Engineering, and Bioengineering, where understanding molecular structures, chemical kinetics, and thermodynamics is crucial.
Further Mathematics, Computer Science, and Design & Technology are valuable additions to round out your subject profile. Further Mathematics can be valuable preparation for mathematically intensive engineering courses and may be recommended or required by some universities or specific programmes, while Computer Science and Design & Technology offer direct advantages for Software, Mechatronics, and Robotics pathways.

Here are example subject combinations aligned with major engineering disciplines:

  • Option 1: Mathematics, Further Mathematics, Physics, Chemistry or Computer Science
  • Option 2: Mathematics, Physics, Chemistry, Biology or Further Mathematics
  • Option 3: Mathematics, Further Mathematics, Physics, Computer Science
As with medical degrees, high academic performance is critical, with top universities typically expecting A* / A grades in core subjects like Mathematics and Physics. Additionally, competitive programs may require specific engineering admissions tests alongside evidence of technical project work, practical problem-solving ability, and quantitative aptitude.

A Level subject choices for Economics

Pursuing a degree in Economics opens doors to careers in finance, policy, consulting, and academia. Because economics programs range from pure quantitative and mathematical economics to social science and policy-focused tracks, choosing the right A Level subjects helps ensure you develop both strong quantitative modeling capabilities and critical essay-writing skills.
Mathematics is required for many competitive Economics degrees, particularly courses with a strong quantitative focus. It provides the necessary foundation for calculus, statistics, linear algebra, and econometrics, tools central to modern economic analysis.
Economics can provide useful preparation, as it introduces core principles of microeconomics, macroeconomics, market structures, and economic theory, giving you a strong conceptual head start. However, it is actually not mandatory for many Economics degrees.
Further Mathematics can be particularly useful for mathematically intensive Economics degrees and is expected or recommended for some programmes, as it demonstrates superior mathematical fluency and analytical rigor.
Humanities and Social Sciences, such as History, Politics, Philosophy, Geography, and English Literature, demonstrate strong essay-writing, structured argumentation, critical evaluation, and qualitative analysis skills, which are crucial for policy and essay-based components of economics degrees.
Sciences like Physics and Chemistry reinforce logical problem-solving and rigorous analytical thinking, complementing the quantitative focus of Mathematics.

Here are examples of subject combinations aligned with different economics degree pathways:

  • Option 1: Mathematics, Economics, Further Mathematics, History or Politics
  • Option 2: Mathematics, Economics, Physics or Chemistry, Further Mathematics
  • Option 3: Mathematics, Economics, Geography or Psychology, English Literature
Top universities typically expect high grades (A* / A) in key subjects like Mathematics. Furthermore, competitive applications often require strong performance on admissions assessments along with evidence of well-rounded analytical rigor across both quantitative and qualitative disciplines.

FAQs

Three A Levels are a common qualification route for university applicants, although some students take four. Taking an additional subject does not automatically strengthen an application, so students should consider their school’s recommendations, workload and the specific requirements of their target universities. In many cases, achieving strong grades in the required subjects is more important than taking an additional A Level.
For highly competitive universities, Further Mathematics is strongly recommended or even essential for quantitative disciplines. It builds advanced calculus and algebra skills that make the transition to degree-level study significantly easier.
Not necessarily. While A Level Economics provides a helpful introduction to fundamental concepts, top universities place far greater weight on A Level Mathematics for Economics degrees. Subjects like History, Geography, or Physics are equally respected alongside Mathematics.
Choose a subject combination anchored by versatile core subjects like Mathematics and a physical science or essay-based subject. This keeps multiple pathways open—for example, combining Maths, Chemistry, Physics, and Biology keeps both Medicine and Engineering viable options.
Universities generally specify their own subject requirements, so you should prioritise the subjects required or recommended for your intended degree.
