Biology A-Level (AQA)

Course Overview

Biology is the study of life, from the molecular level, through cells and organisms to populations and ecosystems. Biologists strive to understand the world around them, from the complex workings of living organisms to the ecological phenomena affecting our planet.

“This course involves a lot of hard work; which requires much understanding on a variety of subjects/topics. Although hard work, Biology is fun and interesting most of the time, with a good teacher/student relationship”


  • Biology and disease – In this unit you will learn about the systems through which we exchange substances with our environment and the diseases that affect them. You will study the transport of substances, the role of enzymes and the immune system and you will interpret data relating to the risk factors associated with disease.
  • The variety of living organisms – You will learn how the extensive variety of living organisms is reflected in similarities and differences in their DNA, biochemistry and cellular organisation.
  • Populations and environments – This unit involves the study of ecosystems. You will learn about energy flow and nutrient cycles, photosynthesis and respiration , environmental issues and evolution.
  • Control in cells and organisms – You will learn about control systems, nerves and muscles, sensitivity and coordination. You will study the genetic code and the applications of recombinant DNA technology.
  • Investigative and practical skills – Throughout your study you will develop your ability to make, record and communicate reliable and valid observations and measurements. You will be able to analyse, interpret, explain and evaluate the methodology, results and impact of your own and others’ investigations.

One of the most popular A-level courses, Biology attracts students studying a wide range of other subjects and opens up a vast array of career options. Biology is a prerequisite for Medicine, Dentistry and many other health and clinical professions. Many biology students go on to study biology related degree courses such as Marine Biology, Forensic Science and Environmental Sciences, while others go on to pursue degree courses unrelated to Biology such as Law or Accounting.

Whatever field you choose to work in, you will find A-level Biology a rewarding and challenging course which develops many of the skills essential for a successful career.

You should be on track to achieve a minimum of 5 GCSEs at grades 4 - 9, including at least grade 5 in Biology/Combined Science, Maths and English. To be successful on this course you should ideally have a grade 6+ in Sciences and Maths.
