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 even 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 in the UK recommend (or require) at least a grade 5 or 6 (B) in GCSE Biology, or in Combined Science, before you can enrol on A Level Biology.

This is because A Level Biology builds on knowledge and skills from the GCSE syllabus, and jumps in complexity and depth.

However, some distance learning and online providers offer more flexibility.

Is It Possible to Enrol Without GCSE Biology?

Yes, especially for adult learners or those with relevant experience.

At Study from Home, we may accept learners without a GCSE in Biology if you have a good GCSE in another science subject (such as Chemistry or Physics), or if you can demonstrate an understanding of basic science concepts.

For students who haven’t studied biology for several years, we strongly recommend brushing up on your science knowledge before starting the course.

What are the entry requirements for A Levels?

What If I Don't Meet the Entry Requirements?

Don’t worry—there are several ways to boost your chances:

• GCSE Biology or Combined Science: You can study for and take GCSE Biology or Combined Science as a private candidate first.
• Preparatory Courses: Consider an introductory science or biology course to refresh your skills.
• Demonstrate Experience: If you have work or volunteer experience in science, healthcare, or a related field, let your provider know.
