What is an A level?
A level stands for Advanced Level. A levels are Level 3 qualifications regulated by the Office of Qualifications and Examinations Regulation (Ofqual) and offered by four main awarding bodies in England, Wales, and Northern Ireland: AQA, Pearson Edexcel, OCR, and WJEC. In Scotland, the equivalent qualification is the Scottish Highers, which follows a different structure.
Each A level covers a single subject — Biology, Maths, History, Psychology, Business, English Literature, Chemistry, and many others. The qualification is assessed primarily through written examinations sat at an approved exam centre at the end of the course, with some subjects including a coursework or practical element.
Who studies A levels online as an adult?
Adults choose online A levels for several reasons. Some left school with GCSEs but not A levels and now want to progress to university. Others are changing career direction and need specific subject knowledge — for example, Biology for a nursing degree application or Maths for an engineering conversion. A smaller group take A levels for personal development or to meet a professional licensing requirement.
- Adults aged 19+ who left school without A levels and want to enter university
- Career changers who need a specific subject to meet a degree entry requirement
- Professionals in fields such as teaching, science, or law who need a subject-level qualification
- Anyone who failed or did not complete their A levels at school and wants to retake them
- Mature learners who want the intellectual challenge and formal recognition of A level study
How does online A level study work?
When you study an A level online, you receive learning materials — typically written modules, video explanations, and practice questions — from your course provider. You work through the content at your own pace, supported by tutor feedback on assignments and practice papers. You do not attend a classroom.
To sit the actual A level examination, you register as a private candidate at an approved exam centre. This is separate from your online course provider. Exam centres are run by schools, colleges, and independent centres that are registered with the relevant awarding body. You pay the exam fee directly to the centre.
Most online A level providers align their materials to a specific awarding body specification — for example, AQA A level Biology or Pearson Edexcel A level Maths. The choice of specification matters because it determines which exam centre you need to register with and what content you will be tested on.
How long does an A level take online?
The standard timeline for an A level is two years, matching the school-based route. Many adult learners, however, choose a fast-track approach and complete in 9–12 months by studying more intensively. The right timeline depends on the subject (Maths and sciences tend to require more practice hours than essay-based subjects) and how many hours per week you can dedicate.
