BIOLOGY

Biology A-level will give you the skills to make connection and associations with all living things around you.  Biology literally means the study of life and if that's not important, what is?  Being such a broad topic, you're bound to find a specific area of interest, plus it opens the door to a fantastic range of interesting careers.

Assessments

Biology, at A Level, builds on the knowledge and practical skills gained at KS4 as scholars embark upon a journey through the AQA A-level Biology 7402 course.

In A Level Biology, scholars work towards 100% terminal examinations, comprising of three papers.  At least 15% of the marks for A-level Biology are based on what you learned in your practicals.

Paper 1 (35%)

Any content from topics 1-4, including relevant practical skills

  • 76 marks: a mixture of short and long answer questions
  • 15 marks: extended response questions

Paper 2 (35%)

Any content from topics 5-8, including relevant practical skills

  • 76 marks: a mixture of short and long answer questions
  • 15 marks: comprehension question

Paper 3 (30%)

Any content from topics 1-8, including relevant practical skills

  • 38 marks: structure questions, including practical techniques
  • 15 marks: critical analysis of given experimental data
  • 25 marks: one essay from a choice of two titles
