Why choose A level biology?

A level biology explores the living world, from the molecular and cellular levels to the interactions between organisms and their environments. Students study the structure and function of biological molecules, cells, genetics, and ecosystems – as well as advanced topics such as homeostasis, energy transfers, gene expression, and evolution.

The course builds strong scientific thinking and practical skills, including analysis, evaluation, and experimental design. Students also develop synoptic essay writing skills, which are highly valued by universities.

This course can be taken at AS or A level.

Course type: A level

Board: AQA

Entry requirment: Grade 7-7 in GCSE combined science or grade 7 or above in GCSE biology with grade 6 in maths, physics and chemistry

How will A level biology be delivered?

The course is delivered through a combination of theory lessons, practical work, and independent study over two years. Students will complete required practical activities and learn to apply their understanding in a range of contexts.

In year 12, you will study:

  • Biological molecules
  • Cells
  • How organisms exchange substances with their environment
  • Genetic information, variation, and relationships between organisms

In year 13, you will study:

  • Energy transfers in and between organisms
  • How organisms respond to changes in internal and external environments
  • Genetics, populations, evolution, and ecosystems
  • The control of gene expression

Assessment

Assessment is through written examination at the end of each course:

AS Level (if taken as a standalone qualification)

  • Two written papers – each 1 hour 30 minutes
  • Each paper contributes 50% of the AS grade
  • Assesses content from year 12 only

A Level

  • Paper 1: Year 12 content – 2 hours – 35% of A Level
  • Paper 2: Year 13 content – 2 hours – 35% of A Level
  • Paper 3: Synoptic and practical-based questions – 2 hours – 30% of A Level

Students will also complete a series of required practicals, which are reported separately as a practical endorsement but do not contribute to the overall A Level grade.

Progression

A level biology is a versatile and well-regarded qualification that supports entry into a wide range of higher education courses and careers. It is especially relevant for science, healthcare, and environmental fields.

Studying this course can help students to:

  • Access university degrees such as medicine, veterinary science, nursing, dentistry, physiotherapy, and psychology
  • Enter careers in biomedical sciences, genetics, neuroscience, forensics, ecology, botany, or zoology
  • Develop transferable skills in research, analysis, scientific writing, and problem-solving
  • Pursue roles in the NHS, pharmaceutical industry, conservation, education, or science communication
