What are A-levels and IB?

A-levels (Advanced Levels) are a two-year academic programme that allows students to specialise in 3–4 subjects. Considered the “gold standard” of UK education, A-levels are the traditional route into British universities.

IB (International Baccalaureate Diploma Programme) is also a two-year course, but with a broader academic structure: students study six subjects, complete an Extended Essay, take a Theory of Knowledge (TOK) course, and participate in Creativity, Activity, Service (CAS) projects.

Both programmes are widely accepted by UK and international universities but follow different educational philosophies.

Programme structure

A-levels:

• Students choose 3–4 subjects to study in depth.
• Allows for specialisation in a particular field.
• Ideal for students who already know their intended university major.

IB:

• Students take six subjects from different groups (languages, humanities, sciences, mathematics, the arts).
• Three subjects are taken at Higher Level (HL), three at Standard Level (SL).
• Includes core components: Extended Essay, Theory of Knowledge (TOK), and CAS (extracurricular activities).

Grading systems

A-levels:

• Grades range from A* (highest) to E (pass).
• Final grades are based primarily on end-of-course exams.
• Coursework is required for certain subjects, such as art or media.

IB:

• Each subject is graded on a scale of 1 to 7.
• Up to 3 additional points are awarded for TOK and the Extended Essay.
• The maximum score is 45 points; 24 is the minimum passing score.

Study focus: specialisation vs breadth

A-levels:

• Ideal for students who have already chosen a subject area.
• Offers academic depth and concentrated learning.
• Popular among applicants for medicine, engineering, economics, and sciences.

IB:

• Encourages academic breadth and a more generalist approach.
• Promotes critical thinking, time management, and interdisciplinary learning.
• Great for students who want to keep multiple options open or pursue international studies.

Which one do universities prefer?

UK universities — including Oxford, Cambridge, UCL, LSE, and other members of the Russell Group — accept both qualifications. However:

• A-levels are the standard route for most UK applicants and are often explicitly listed in admission requirements (e.g., “A*AA in three A-levels”).
• IB is equally respected, especially for international students, though universities may specify required total points and HL subject scores (e.g., “38 points, with 6-6-6 in HL subjects”).

In short: both are accepted, but you need top marks either way. IB is not automatically a plus — it’s all about your results.

Subject choices and flexibility

A-levels:

• Over 60 subjects available.
• Students have complete freedom to focus on a specific academic area (e.g., all science or all humanities).
• Some subjects (like Travel & Tourism or Media Studies) are less valued by top universities — better to choose them as additional subjects only.

IB:

• You must choose subjects from six categories.
• Language, humanities, science, maths, and the arts are all required (though arts can be substituted).
• Less flexibility for students who want to focus only on one area, such as pure sciences or humanities.

Difficulty and exam formats

A-levels:

• Fewer subjects mean more focused revision.
• Ideal for students who prefer depth over breadth.
• Exams are straightforward and subject-focused.

IB:

• Requires managing six subjects plus core components.
• Demands excellent organisation and time management skills.
• Widely considered more intense and time-consuming due to projects, essays, and continuous assessment.

International recognition

• IB is a globally recognised diploma and accepted by universities worldwide — especially in Europe, North America, and Asia.
• A-levels are highly regarded in the UK, Australia, Singapore, Hong Kong, and some parts of North America and Europe.

If you’re planning to apply outside the UK, IB may give you more flexibility. But A-levels are equally strong if your focus is on British or Commonwealth universities.

How to decide what suits you

Choosing between A-levels and IB depends on your academic goals, strengths, and preferred learning style. Here’s a breakdown to help guide your decision:

Choose A-levels if you:

• Know what subject you want to study at university.
• Prefer to dive deep into 3–4 focused subjects.
• Work best with a more structured, exam-based system.
• Are aiming for top UK universities (especially in science, engineering, or medicine).
• Would rather avoid long essays and extracurricular projects.

Choose IB if you:

• Want to keep your university options open.
• Enjoy learning across multiple disciplines.
• Are good at managing time and juggling several projects at once.
• Plan to apply to universities internationally (e.g., US, Canada, Europe).
• Want to develop broad analytical and research skills alongside academic knowledge.

Whichever route you choose, your success will depend on your motivation, discipline, and ability to keep up with the demands of the programme.

Frequently Asked Questions (FAQ)

— Is A-level easier than IB?

A-levels involve fewer subjects, so in that sense, they’re more focused. However, they demand depth. IB is broader and often considered more demanding due to the number of components and continuous assessment.

— Which is better for Oxford or Cambridge?

Both are accepted. The key is to score well and choose appropriate subjects. For example, medicine applicants must have Chemistry and Biology in A-levels or at HL in IB.

— Can I take both A-levels and IB?

No, they are separate programmes. However, some schools allow you to take additional A-levels alongside IB subjects, though this is rare and very demanding.

— Is IB only for humanities students?

Not at all. IB includes strong science and maths options, though the structure may limit your ability to focus purely on technical subjects. If you're aiming for engineering or physics, A-level may offer more flexibility.

Both A-levels and IB are rigorous, internationally respected programmes that open doors to top universities in the UK and beyond. If you're looking for depth and specialisation, A-levels may be the better fit. If you're drawn to academic breadth, global opportunities, and independent research, the IB might suit you more.
