A level Biology

Are you interested in unravelling the mysteries of life, from the tiniest cells to the grandeur of ecosystems? The International A level in Biology sets you on a path of discovery that takes you through molecules and gene technology to biodiversity and immunity. But it’s not just about the study of living organisms; you’ll develop transferable skills in maths and practical techniques too. The 16 core practical experiments of the International A level are covered in depth within the course, and assessed via examination paper, ensuring you’re thoroughly versed in the procedures and techniques for testing out the theoretical knowledge covered in this course.

Progression to University

A Biology A level is an essential or highly desirable requirement for a range of university courses, including medicine, dentistry, pharmacy, veterinary science, biology, biochemistry, genetics, environmental science, and nursing. It serves as a foundational qualification for careers in healthcare, research, and life sciences. Additionally, a Biology A level can be beneficial for courses in fields like psychology, anthropology, and forensic science, as it provides a strong understanding of biological principles and scientific methods. Whether aspiring to become a doctor, researcher, or environmental scientist, a Biology A level opens doors to a wide array of academic and professional opportunities in the life sciences.

Pupils looking to study medicine at university may wish to combine Biology with a Chemistry A level, and will find that for some universities, a Chemistry A level is required, and Biology is optional.

We also offer the following A levels

Our core A level subjects are taught in group classes via a combination of interactive self-study lessons and live lessons led by an expert teacher: 

We have an even wider selection of A levels available via our independent learning and tutoring programmes, including:
