You have 2 options: 

  • National 5 Biology
  • Higher Human Biology (if you have previously passed N5 in biology or another science).

Higher Human Biology contains 3 units: It presents DNA, cells and human body systems, making it an ideal choice for those interested in, for example, healthcare-based careers. 

Human Cells

Physiology and Health  

Neurobiology and Immunology



The S5 options are open to you but with the addition of Advanced Higher Biology (if you have passed Higher). 

This has 3 units: It gives you a deeper understanding of those aspects of biology which prepare you for the study of this subject beyond school level. 

You will carry out an independent investigation into a topic of interest, in addition to developing knowledge of investigative techniques, proteins, the cell cycle, evolution and behaviour.
