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

This is because A Level Biology builds directly on GCSE content and introduces more advanced scientific concepts, practical skills, and analytical techniques.

However, many 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 science experience.

At Study from Home, we may accept learners without a GCSE in Biology if you have a good GCSE in Combined Science, Chemistry, or Physics, or if you can demonstrate strong literacy and numeracy skills.

For students who haven’t studied biology before, we strongly recommend brushing up on GCSE-level science 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 as a private candidate first.
• Preparatory Courses: Consider an introductory science course to refresh your knowledge.
• Demonstrate Experience: If you have work or volunteer experience in healthcare, lab work, or a science-related field, let your provider know.
