IB Biology

About the IB Biology

IB Biology is a course in Group 4 (Experimental Sciences) of the IB Diploma Programme. With interest, practice, focus, and the right guidance, IB Biology can be both a rewarding and important subject to study and excel at.

IB Biology typically involves a 2 year course with seamlessly interlinked practical and theoretical lessons that aim to enable the student to be scientifically creative and knowledgeable. One is expected to apply and evaluate scientific information, value scientific collaboration and communication, and be aware of the ethical implications and limitations of using science and technology.

IB Biology HL Syllabus

IB Biology tends to stick very closely to the published syllabus. However, many questions do appear ‘out-of-syllabus’ simply because students are also required to think out of the box instead of merely regurgitating facts and figures, and memorizing formulas. Hence it is not sufficient to be just familiar with with the Biology syllabus topics, but additionally, a student needs to understand and prepare to apply the concepts thoroughly.

The topics covered in the IB Biology HL can be divided into four categories:


Additional Higher Level (AHL)


Practical Scheme of Work

Cell biology

Nucleic acids

Neurobiology and

Topic chosen for internally assessed individual investigation

Molecular biology

Metabolism, cell respiration and photosynthesis

Biotechnology and bioinformatics

Practical work arranged by school and otherwise


Plant biology

Ecology and conservation



Genetics and evolution

Human physiology


Evolution and biodiversity

Animal physiology

Human physiology

*a practically or theoretically based collaborative activity between students (across or within schools) from different group 4 (experimental science) subjects to promote interdisciplinary cooperation, understanding of scientific processes, and appreciation of environmental, social, and ethical implications of science and technology

How can Prep Zone help?

Prep Zone offers premier training courses for IB Biology. Our individual classes are completely customisable. You decide how many sessions you want, you decide how long each session should be, you decide how frequently you would like to have sessions, and most importantly, you decide when you want the sessions. We work 9 a.m. to 10 p.m. every day of the year (except some public holidays). Sessions can be 1 hour long, or as much as 3-4 hours long – as we charge by hours. Individual sessions are ideal for focusing on stuff that you’re particularly weak at, clearing doubts, and revising practice material/mock exams.
