IB Biology Past Papers and Revision Resources
IB Biology papers are being added to this page, so the list below may be empty for now.
Biology papers test recall of keywords, interpretation of data and diagrams, and longer written answers that need a complete chain of reasoning. IB papers differ by paper number, level and time zone, so the sections below explain how to pick the right ones for Biology.
IB subject guides are revised on a cycle, with a first-assessment year, so confirm that your guide version matches the papers you practise. Internal assessment work is not part of past papers. Files are published by International Baccalaureate; Trinity Tutors is an independent tutoring service and is not endorsed by or affiliated with the board.

How to Use Biology Past Papers Effectively
Past papers are most useful when each one ends with a marked script and a short list of things to fix. This is a simple routine for IB Biology.
How to identify the paper, session and variant
IB papers are named by subject, paper number and level. Paper 1, Paper 2 and, in some subjects, Paper 3 are separate examinations, and many papers are set for either Standard Level (SL) or Higher Level (HL).
IB examinations take place in the May and November sessions, and some papers are set in more than one time zone (TZ1, TZ2) in the same session.
Check the level (SL or HL), the paper number and the time zone, and use the papers that match the level you take.
Attempt a paper under timed conditions
Choose a paper that matches your course, set the time allowed on the front page, and work without notes. Stopping early to look something up hides the gaps you are trying to find.
Answer in the language of the question: when a command word says describe or explain, include the process and the reason.
Learn keywords in context, because mark schemes often credit a specific term and not a general description.
Read the data or diagram first, because many marks come from quoting figures; then write answers with one point per mark available.
Checking your answers
No mark schemes have been added for Biology yet. Until they are, ask your teacher to check your work or look for the matching mark scheme on IB's website.
Compare the key terms in the mark scheme with your own wording, and check how many separate points a question expects.
Typical slips are an answer that is true but not specific enough, missing the comparative word in a comparison, and describing when the question asks for an explanation.
Keep an error log and plan your revision
After each paper, write down every lost mark in a log. Record whether a mark was lost because a keyword was missing, an explanation stopped halfway, data was not quoted, or the command word was misread.
Then turn the log into a short weekly plan: choose two or three topics, revise them from your notes, and test them with fresh questions. Spread the papers you have across several weeks instead of attempting them all at once.
A good week pairs one paper with a keyword review of the topics you missed, followed by rewriting two long answers from memory.
Revise by body system or topic, then use topic questions to practise writing complete, point-by-point answers.
Check that the syllabus version matches
IB subject guides are revised on a cycle, with a first-assessment year, so confirm that your guide version matches the papers you practise. Internal assessment work is not part of past papers.
Frequently Asked Questions
How do I find the correct IB Biology paper?
Check three things on the paper: the session and year, the paper number, and the variant or level when there is one. IB papers are named by subject, paper number and level. Paper 1, Paper 2 and, in some subjects, Paper 3 are separate examinations, and many papers are set for either Standard Level (SL) or Higher Level (HL).
Which Biology syllabus version should I choose?
IB subject guides are revised on a cycle, with a first-assessment year, so confirm that your guide version matches the papers you practise. Internal assessment work is not part of past papers.
Where can I find the matching mark scheme?
No mark schemes have been added for this subject yet. Check IB's website or ask your teacher, and see the list above as new files are added.
Are all IB Biology past papers on this page?
No. This page lists only the files that have been added so far, and some sessions may be missing. For the full official list, use IB's own website.
Should I use Standard Level or Higher Level papers?
Use the papers that match the level you take. Check the level (SL or HL), the paper number and the time zone, and use the papers that match the level you take.
Are these files endorsed by IB?
No. The papers are published by International Baccalaureate. Trinity Tutors is an independent tutoring service and is not endorsed by or affiliated with the board, and it cannot promise any particular grade or result.
How detailed should Biology answers be?
Match the marks available: one clear, specific point for each mark, using the keywords from the syllabus. A mark scheme shows what a single credited point looks like.
Can a tutor help me with Biology?
You can browse a Biology tutor or contact us with the board, level and topics that cost you marks, and we will say honestly whether we have a suitable tutor.
Past papers, mark schemes and reports are the property of their exam boards. They are shared here for study and practice; always check the board's own website for the current syllabus and rules.
