What is the difference between GCSEs and A Levels?
GCSEs (General Certificates of Secondary Education) and A Levels (Advanced Levels) sit on different rungs of the national qualifications ladder. On the Regulated Qualifications Framework (RQF) maintained by Ofqual, a GCSE at grades 9 to 4 is a Level 2 qualification, while an A Level is a Level 3 qualification, the same level as BTEC Nationals and T Levels (gov.uk: what qualification levels mean).
The practical differences matter more than the labels:
| Column 1 | GCSE | A Level |
|---|---|---|
| Qualification level | Level 2 (grades 9 to 4); grades 3 to 1 are Level 1 | Level 3 |
| Typical age | 14 to 16 (school Years 10 to 11) | 16 to 18 (sixth form), or any age online |
| Grading | 9 to 1 (9 highest) | A* to E |
| Subjects taken | 8 to 10 at school; adults usually take one or two at a time | 3 typical at school; one at a time is common online |
| Study depth | Broad foundation across a subject | Deep, specialised, essay- and problem-heavy |
| Exam boards | AQA, Pearson Edexcel, OCR, WJEC/Eduqas, CCEA (UK-wide) | AQA, Pearson Edexcel, OCR, WJEC/Eduqas, CCEA (UK-wide) |
| UCAS points | None | Yes: A* = 56, A = 48, B = 40, C = 32, D = 24, E = 16 |
| Used for | College/sixth form entry, apprenticeships, job screening (English and maths) | University entry, higher apprenticeships, career changes |
The headline distinction: employers screen on GCSE English and maths; universities select on A Levels.
Do you need GCSEs to do A Levels?
Formally, no. The main exam boards set no age restrictions or prior-qualification prerequisites for sitting an A Level as a private candidate. Anyone can register at an approved exam centre.
In practice, schools and sixth forms set their own entry bars, often grade 6 or above in the subject you want to study. Online providers are more flexible: Lift College A Level courses have no formal entry qualifications, though Lift College recommends being comfortable working at GCSE level in related subjects, for example grade 5 or above in GCSE English Language for A Level Psychology. See our A Level entry requirements guide for more detail.
Two GCSEs are worth having regardless: English Language and Maths at grade 4 or above. Most universities and many employers require them alongside A Levels, whatever your degree subject.
Can you skip GCSEs and go straight to A Levels?
Yes. If you're an adult learner, you can usually skip straight to A Levels, with two caveats.
When skipping ahead works:
- You left school before finishing GCSEs but have work experience or self-taught knowledge in the subject
- You studied abroad and hold equivalent qualifications
- You need a specific A Level (for example, Biology for nursing, Psychology for a psychology degree) and don't want to spend a year on a GCSE you don't need
When to take the GCSE first:
- Maths-heavy A Levels (Maths, Physics, Chemistry) assume fluent GCSE-level algebra. Starting without it is a common reason learners struggle
- Your target university course requires GCSE English and Maths at grade 4 or above and you don't hold them (you can study them alongside your A Level)
A sensible middle route many adults take: enrol on the A Level, and add a GCSE course in English or Maths alongside it if a university offer demands it.
Which is harder, GCSEs or A Levels?
A Levels, clearly. The move from GCSE to A Level is widely described as a big step up. Content is deeper, questions demand analysis rather than recall, and grade boundaries are less forgiving. Subjects like Physics, Chemistry and Further Maths are often rated hardest: see our guide to the hardest A Levels.
That said, adults often find A Levels more manageable than they feared: you choose subjects you care about, study one at a time, and bring real-world context a 16-year-old doesn't have.
How long does each take?
At school: GCSEs take two years (Years 10 to 11), A Levels two years (sixth form).
Online, you set the pace. Lift College GCSE and A Level courses typically take 12 to 18 months per subject, studied at your own pace, and your real deadline is the exam series you enter. Exams run in the May to June series (plus November resits for GCSE English Language and Maths). Read how studying A Levels online works for the full picture.
GCSEs or A Levels for university?
Universities select primarily on A Levels (or equivalent Level 3 qualifications). They carry UCAS tariff points; GCSEs don't. But GCSE English and Maths at grade 4 or above are a common baseline requirement, and competitive courses (medicine, law, education) also look at GCSE profiles. A common route into university for adult learners is two or three A Levels plus GCSE English and Maths. See our guide to university progression with A Levels.
What order should adult learners take them in?
- Check your target first. Find the actual entry requirements for the job, apprenticeship or degree you want, then work backwards.
- English and Maths GCSE first if you need them. They unlock everything else and are required almost everywhere.
- Go straight to A Level if you have GCSE-level knowledge in the subject (formal or not) and your goal needs a Level 3 qualification.
- Don't collect qualifications you don't need. One targeted A Level often beats three GCSEs for career change.

Whether you need GCSEs first or can start at A Level depends on where you are heading and what you already know.
