A Level Biology is a facilitating subject that expands on the principles taught at GCSE and allows students to increase their knowledge and understanding of different topics through detail and use of relevant mathematical techniques and calculations.

Course content:

Year 12

Focuses on the structure, function and interaction of biological molecules, and moves on to study cells and their organelles. This is extended to cover transport of substances across cell membranes and the way the immune system works. Following this, the mechanisms through which organisms exchange substances with their environment are examined. There is a lead into ecology by considering variation, genetic information and relationships between organisms which continues in the second year.

Year 13

Addresses how energy transfers in and between organisms and how organisms respond to changes in their environment. This is followed by study of genetics, populations, evolution and ecosystems. The course finishes with a look at recent developments in gene technology and the control of gene expression.

Assessment criteria:

Three two-hour exams, each of approximately equal weighting and covering topics from the whole course (Paper 1 – Year 1 content, Paper 2 – Year 2 content, Paper 3 – whole content) as short and long answer, extended response, comprehension and questions on practical techniques, critical analysis of experimental data and an essay (Paper 3).

10% of marks assess mathematical skills at higher tier GCSE level, 15% are for practical knowledge and understanding. Students also have to successfully complete the Practical Endorsement via the 12 required practical activities over the two-year A Level course.
