IB Biology

Welcome to all IB Biology students. I have created this blog for you – it is primarily a revision resource so virtually everything on here you need to know. There are some ‘extras’ to extend your knowledge further than the syllabus but they will be clearly labelled.

I have tried to cover every sub-topic with a powerpoint (that includes the assessment statements from the IBO) and revision notes (downloadable as a word document). I have also added YouTube clips and tutorials (lessons/podcasts that are particularly good at explaining parts of the syllabus), as well as links to other sites and the odd song.

For the complete IB Biology guide for the new syllabus (first exams in 2016), click here.

Further help:
