O Level Biology 5090 topical question sets 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. Questions here are grouped by syllabus topic, so you can practise one area at a time before returning to full papers.
Check that 5090 is the code on your course outline and which examination years your syllabus version covers, because content and paper structure can change between syllabus versions. Files are published by Cambridge Assessment International Education; 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 O Level Biology 5090.
How to identify the paper, session and variant
Cambridge papers are named from the syllabus code, the session, the type of document and the paper number. A file such as 5090_s23_qp_12 reads as: syllabus 5090, May/June 2023, question paper, paper 1 variant 2.
In Cambridge file names m means February/March, s means May/June and w means October/November, followed by the two-digit year.
The two digits after the document type are the paper number and the variant: 12 is paper 1, variant 2. Variants are different versions of the same paper set to the same standard, so use the one that matches your entry or practise several.
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 CAIE'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
Check that 5090 is the code on your course outline and which examination years your syllabus version covers, because content and paper structure can change between syllabus versions.
