Understanding A-Levels: AS vs. A2 - What’s the Difference?

What Are A-Levels?

A-Levels (Advanced Level qualifications) are subject-based exams typically taken by students aged 16-18 in the UK. They play a crucial role in university admissions, as students usually need three strong A-Level grades to secure places at top universities.

A-Levels are divided into two parts:

• AS Level (Advanced Subsidiary): Taken in Year 12, usually at the end of the first year.
• A2 Level: Taken in Year 13, forming the full A-Level qualification.

AS vs. A2: What’s Changed?

Until 2015, AS-Levels counted as 50% of the final A-Level grade, but reforms removed this link. Now, AS-Level results no longer contribute to the final A-Level grade.

How Many A-Levels Should a Student Take?

Most students take three A-Levels, but some high-achievers take four. The right number depends on:

• University requirements: Oxbridge and medicine applicants may benefit from four subjects.

• Workload: A-Levels are significantly harder than GCSEs.  Independent study and research are required at this level.

• Course flexibility: Some students prefer to start with four subjects in Year 12 and then drop one in Year 13.

Choosing the Right Subjects

• STEM fields: Maths, Physics, Chemistry, Biology.

• Humanities & Social Sciences: English, History, Geography, Politics, Psychology.

• Creative subjects: Art, Drama, Music.

• Business & Economics: Economics, Business Studies, Accounting.

University Admissions: What Matters More?

Since AS results no longer contribute to A-Levels, universities now rely on: 

• Predicted grades: Based on Year 12 performance.

• Personal statement & references.

• Admission tests & interviews: Required for Oxbridge, Medicine, and Law.
