Advanced Higher Biology Course Specification

What the Course Is

Advanced Higher Biology is a senior-level biology qualification in the Scottish curriculum, taken after Higher Biology or Higher Human Biology. It builds on earlier study and usually prepares learners for university-level biological science or related courses such as medicine, veterinary science, environmental science, or biological research.

The course aims to develop:

• A deep understanding of cellular and organismal biology

• Practical investigative biology skills

• Analytical thinking and scientific literacy

• Ability to evaluate biological research and communicate scientific ideas effectively

Course Structure

The Advanced Higher Biology course is divided into three core units:

1. Cells and Proteins

Covers:

• Laboratory techniques used by biologists

• Proteins and their functions

• Membrane proteins and transport

• Cellular communication and signalling

• Protein control of cell division and regulation

2. Organisms and Evolution

Focuses on:

• Field techniques and sampling methods

• Evolutionary processes like natural and sexual selection

• Variation and sexual reproduction

• Behavioural ecology (sex and behaviour)

• Parasitism and inter-organism interactions

3. Investigative Biology

Develops practical research skills, including:

• Scientific principles and experimental design

• Conducting valid biological investigations

• Data collection and statistical analysis

• Reporting results and critically reviewing scientific work

Assessment Breakdown

Assessment in Advanced Higher Biology includes two main components:

1. Question Paper (External Exam)

• Typically 100 marks (scaled so the exam accounts for roughly 75% of total assessment)

• Includes multiple-choice, structured, and extended-response questions

• Assesses broad understanding, application of knowledge, data handling, and analytical skills

2. Project (Coursework)

• Often worth 30 marks (about 25% of total assessment)

• Students carry out an independent investigation on a chosen biology topic

• Requires planning, experimental or research work, data analysis, and a written report

• Encourages autonomy and critical evaluation skills

Skills and Learning Outcomes

Learners engaging in Advanced Higher Biology will develop:

✅ Deep biological knowledge — at molecular, cellular, and organismal levels
✅ Practical and laboratory skills — including designing and conducting experiments
✅ Analytical thinking — interpreting and evaluating biological data
✅ Scientific communication — clear explanation of methods and findings
✅ Independent research skills — planning and completing a substantial project

Recommended Entry Requirements

While entry is at the discretion of schools/colleges, candidates typically need a strong pass (often A or B) in Higher Biology or Higher Human Biology before progressing to Advanced Higher Biology.
