Quick answer
BioNinja is a free, independent IB Biology resource created by a teacher. Its current site is designed for the course first taught from 2023 and assessed from 2025, with content mapped to both the four themes and 12 biological topics.
About This Resource
The current BioNinja site provides topic notes, course and practical materials, presentations, review notes and worksheets. BioNinja's own 2026 update says the current-course site is still a work in progress: reporting-skills material and quizzes remain incomplete, and some proof-checking and broken-link work is ongoing. The separate old site serves earlier syllabuses, so students should confirm they are using the current version.

Sources and common questions
Is BioNinja updated for the current IB Biology course?
The current BioNinja site says it was built for the new curriculum first taught from 2023 and maps content to its themes and topics. It also states that some reporting-skills content, quizzes, proof-checking and broken-link work remain incomplete.
Does BioNinja cover both IB Biology SL and HL?
The current notes distinguish standard-level content from additional higher-level material. Students should still select the exact course level and verify required content with current school or IB documentation.
Is BioNinja an official IB resource?
No. BioNinja is a free independent educational resource created by a teacher and is not an official International Baccalaureate website.
What is the best way to revise with BioNinja?
Use it for concise explanation and retrieval practice: study one small section, reproduce the process or diagram without looking, complete the matching worksheet and verify any missing syllabus detail with your teacher or current guide.
Notes
How to use this resource
- Use the current ib.bioninja.com.au site for the course assessed from 2025; avoid mixing it with the separate old-syllabus site.
- Read one topic note, close it, draw the mechanism or process from memory and then use a worksheet to test retrieval.
- Check every required syllabus statement against current school or IB materials because BioNinja describes the site as still incomplete.
