In the Biology course, students will need to be able to: use standard form, use significant figures, rearrange equations, use logarithms and have a good grasp of algebra to succeed. A Level Biology is a linear qualification, with students sitting all the A Level examinations at the end of their A Level course. There are three assessments: paper 1 will assess any content from sections 1 to 4 of the course, including relevant practical skills; paper 2 will assess any content from sections 5 to 8 and relevant practical skills; paper 3 is a synoptic paper based on all content from sections 1 to 8, including practical skills. The subject content is broken down into eight sections, each of which has associated mathematical and practical skills (Sections 5 to 8 are designed to be taught in the second year of the A Level course) Section 1: Biological molecules Section 2: Cells Section 3: Organisms exchange substances with their environment Section 4: Genetic information, variation and relationships between organisms Section 5: Energy transfers in and between organisms Section 6: Stimuli, both internal and external, are detected and lead to a response Section 7: Genetics, populations, evolution and ecosystems Section 8: The control of gene expression
