A-Levels (Advanced Level Qualifications) are the primary qualification for university entry in the UK. Successfully completing A-Levels opens doors to thousands of degree programmes and career paths. Here's everything you need to know.
A-Levels are Advanced Level qualifications awarded after two years of post-secondary study (typically ages 16-18 in Years 12-13). Each A-Level is a separate qualification in a specific subject, similar to GCSEs but pitched at a higher academic level.
Most students take 3-4 A-Levels, though some take more. Universities expect students to provide their strongest 3 A-Level grades for degree applications.
| Factor | GCSE | A-Level |
|---|---|---|
| Age | 14-16 | 16-18 |
| Duration | 2 years (Y10-11) | 2 years (Y12-13) |
| Difficulty | Foundation | Advanced |
| Assessment | Broader content | Deeper, more specialized |
| University relevance | Secondary | Primary |
Universities evaluate your best 3 A-Level grades. Taking a 4th is worthwhile if you can maintain high grades across all four. Taking 5+ risks diluting grades and exam performance.
A-Levels are graded A* (highest) to E (lowest), plus U (ungraded). Grade A* is exceptional, representing top 10% of students nationally.
Year 12: Study first year of A-Level content
Year 13: Complete second year, sit final exams
May/June (end of Y13): Final exams, results released August
August: Results day, university decisions made
Common A-Level subjects include Maths, Sciences, English, History, Geography, Languages, Economics, Psychology, Business Studies, Law, and many others. Over 50 subjects are typically available nationally, though individual schools offer 10-30 options.
Most schools require grade 5+ in related GCSEs. However, some schools may accept grade 4 with evidence of ability. Check with your school.
A-Levels are significantly harder than GCSEs. Content is deeper, more abstract, and requires independent thinking. Most students find Year 12-13 more challenging than Y10-11.
Requirements vary: typical competitive universities want AAB or AAA, whilst less selective universities may accept ABB or BBC. Check individual university website for specific requirements.
Rarely possible after Year 12, as most schools require commitment. Some schools allow changes early in Year 12 with evidence of struggle.
You can retake A-Levels. Universities typically accept resit grades, though some competitive programmes prefer first attempts.
