If you’re considering A Level Biology but didn’t take (or pass) GCSE Biology, you’re not alone.

Many adult learners, international students, and recent school leavers wonder if it’s possible to study A Level Biology without the usual background.

What do providers typically require?

Most schools and colleges recommend (or require) at least a grade 5/6 (B) in GCSE Biology or Combined Science before you enrol on A Level Biology.

That’s because A Level Biology builds directly on GCSE content and introduces more advanced concepts, practical techniques, and data analysis.

However, many distance-learning providers (including us) can be flexible for adult learners with strong motivation and suitable literacy/numeracy.

Can I enrol without GCSE Biology?

Often, yes — especially for adult learners or those with relevant science experience. At Study from Home, we may accept learners who have:

• Good grades in GCSE Combined Science, Chemistry or Physics
• Evidence of strong literacy and numeracy (e.g., GCSE English/Maths)
• Relevant experience (healthcare, lab work, science-related roles)

If you haven’t studied science recently, we recommend a quick refresher on GCSE Biology topics before starting the course.

What are the entry requirements for A Levels?

If you don’t meet the recommended requirements

• Take GCSE Biology first: Build confidence by sitting GCSE Biology (or Combined Science) as a private candidate.
• Use free refreshers: BBC Bitesize has concise GCSE Biology summaries and quizzes.
• Strengthen maths skills: Biology includes graphs, magnification, percentage change and basic statistics.

Frequently Asked Questions

Can I take A Level Biology with GCSE Combined Science instead of separate Biology?

Usually yes, especially with a good grade (5/6+). Check provider entry rules.

Do I need the Practical Endorsement to sit the written exams?

No. You can sit the exams without it, but some universities ask for the Endorsement for science courses.

How much maths is involved?

Expect graphs, magnification, rates, percentage change and some basic statistics across the papers.

Is A Level Biology much harder than GCSE?

Yes — there’s a clear step up in depth, application and data-handling. With a good plan, adult learners do well.

Can international or mature students apply without GCSEs?

Many providers (including us) are flexible for adults and international learners — ask our team for guidance.
