You must login or register for free to save your progress!This is the full IB biology syllabus, built as an interactive checklist! The syllabus is broken down by the IB biology syllabus topics, for both IB biology SL and IB biology HL. We recommend you scroll through the IB biology syllabus to familiarise yourself with the content for your IB biology exams.
Your selections are saved and the relevant sub-topics from this IB biology syllabus page will appear alongside our matching videos, notes, flashcards and questions for IB biology. It will synchronise site-wide, so you can update your progress from any of our biology pages, not just this IB biology syllabus page.
