Components & time pressure
Marks per minute shows how fast you have to work — the higher the number, the tighter the time pressure in that paper.

What Cambridge examiners say about Biology
Verbatim quotes from 6 official Cambridge examiner reports (2023–2025). Every quote is attributable to a specific paper and session — these are the things Cambridge markers flag year after year.
Confusing similar scientific terms with very different…
Pairs of similar scientific terms with very different meanings were sometimes confused. For example, some candidates mixed up antibiotics and antibody, antibodies and antigens, and introns and exons.
Using 'water concentration' instead of 'water potential'…
Candidates should use the terms 'water potential' and 'water potential gradient'. The terms 'water concentration' and 'water concentration gradient' are not appropriate.
Imprecise membrane naming
Candidates should be clear when referring to a specific membrane. If it is the membrane that surrounds the cell, it must be referred to as a cell surface membrane.
Most Common Mistakes — Biology (9700)
Based on analysis of 6 official Cambridge examiner reports (2023, 2024, 2025). Avoid these errors to maximise your marks.
Confusing similar scientific terms with very different meanings
Paper 2, Paper 4 · Every examiner report across all sessions (2023–2025)
Using 'water concentration' instead of 'water potential' in osmosis
Paper 2, Paper 4 · Every session, Papers 2 and 4
Imprecise membrane naming — saying 'membrane' instead of the specific membrane
Paper 2, Paper 4 · Flagged in every Paper 2 and Paper 4 report
Saying energy is 'made', 'lost', or 'produced' instead of released/transferred
Paper 4 · Every Paper 4 report
Hardy-Weinberg calculation errors — wrong starting point for p and q
Paper 4 · Every Paper 4 report with genetics questions
Topics Students Struggle With Most
Protein structure — secondary vs tertiary vs quaternary
Hydrogen bonds in secondary structure (between backbone NH and CO groups) confused with those in tertiary structure (between R-groups). Collagen fibres vs collagen molecules repeatedly confused.
Paper 1, Paper 2
Respiration — locations, NAD, and oxidative phosphorylation
Glycolysis placed in mitochondria instead of cytoplasm. NAD called an 'electron carrier' instead of 'hydrogen atom carrier'. Matrix wrongly identified as site of oxidative phosphorylation.
Paper 4
Sources and sinks in phloem transport
'Many identified storage cells of seeds as sinks. This is true as seeds develop but when seeds start to grow (germinate), the storage cells become sources.' Leaves can be sinks for amino acids.
Paper 1, Paper 4
Phospholipid bilayer — counting membrane crossings
'Many thought a molecule of oxygen would pass through 5 or 6 phospholipid layers.' Each membrane = 2 phospholipid layers (bilayer). Students confuse membranes with layers.
Paper 1
Hardy-Weinberg equation application
q confused with q². p² + 2pq lumped together when calculating dominant phenotype. Heterozygote frequency (2pq) frequently halved incorrectly.
Paper 4
Meiosis stages — chromosome behaviour at each stage
Telophase II products: 'Few candidates recognised that telophase II results in four daughter cells.' Chromatids drawn joined at centromere after anaphase II (should be separated).
Paper 4
Immune system — T-cell differentiation and memory cells
'Many thought T-lymphocytes differentiate into T-helper and T-killer cells only at the time of immune response.' They differentiate during maturation in the thymus. Memory CELLS (not antibodies) provide long-lived immunity.
Paper 2, Paper 4
Genetic technology — restriction enzymes, recombinant DNA
'Most candidates had difficulty recalling knowledge from 19.1 Principles of genetic technology.' Restriction enzymes cut DNA (not mRNA). Role of ligase poorly known.
Paper 4
Biology (9700) — Cambridge AS & A Level Full Archive 2002–2026
This page contains all 1711 available papers for Cambridge A Level Biology (9700) — 60 exam sessions from 2002 to 2026. Each session includes question papers, mark schemes, and where available, examiner reports and grade threshold documents. All files are free to download as PDF — no account required.
Cambridge A Level Biology (9700) is examined through multiple paper components. Question papers are available in two or three variants per session (v1, v2, v3) — each variant is sat in a different time zone but covers the same syllabus content and is equivalent in difficulty. The paper number in the filename indicates which component: for example, 9700_qp_12 is Paper 1, Variant 2.
Mark schemes for 9700 show the exact marking points accepted by Cambridge examiners. Many questions have multiple acceptable phrasings — look for 'accept', 'allow', and 'credit' in the mark scheme to understand the full range of valid responses. Examiner reports (where available) reveal the most common errors made by the cohort and what top-band answers looked like, making them essential reading before the actual exam.
The most effective way to use this archive is to attempt past papers under timed exam conditions, then analyse your mark scheme results by component. Track which paper components and question types you score lowest on — this tells you exactly where to focus revision. Grade threshold documents show the minimum mark needed for each grade in that specific session, which helps calibrate how your practice scores translate to actual grades.
