Complete guide to 9700 Biology A-Level: paper structure, how Cambridge mark schemes work, common mistakes, revision plan, and marking your answers with MarkScheme.
Cambridge Biology (9700) is one of the most searched A-Level subjects for past papers and mark scheme help. This guide explains how the syllabus is examined, how marks are awarded, and how to turn practice into real marks — not just completed pages.

Past papers are labelled 9700/XX where XX is the component (paper) number for that session. Always check you are practising the right component for your route.
How the papers are structured
Multiple choice (Paper 1), AS structured (Paper 2), A2 structured (Paper 4), and practical skills (Paper 3/5).
Download papers from Cambridge International or your school portal, then mark with the official mark scheme for that exact session and question number.
How mark schemes work for Biology
Mark schemes use acceptable answers, allow lists, and reject lists. Precision matters: wrong terminology often scores zero even if the idea is right.
When you self-mark, read the scheme before you look at your answer — otherwise you unconsciously accept partial credit.
Common mistakes students make on 9700
- Vague answers where the scheme demands a named process
- Confusing similar terms (e.g. transcription vs translation)
- Not linking data in graph questions to biological mechanism
If the same mistake appears twice in one week of marking, it is a revision priority, not bad luck.
A practical revision plan with past papers
- Learn definitions as mark-scheme phrases, not paraphrases
- Practice data-analysis questions with past Paper 4
- Pair content revision with MCQ timed sets
Rule of three: attempt → mark with scheme → rewrite the weakest part. Skipping step two is why students feel they are "doing past papers" without grades moving.
Marking homework and textbook questions
Not every question comes from a past paper. On MarkScheme, choose My question, select Biology (9700), add the question (photo or text), upload your answer, and get Cambridge-style feedback (method marks, bands, or point marks depending on the question type).
