What Cambridge examiners say about Chemistry
Verbatim quotes from 11 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.
Imprecise curly arrows in organic mechanisms
A curly arrow should start clearly on a bond or on a lone pair and the arrowhead should point clearly in the direction of the destination of the electron pair.
Stating facts without explaining HOW or WHY
Candidates are reminded to address 'explain' questions fully — not merely to state facts or rules of thumb, but then to show how these combine to give reasons for chemical phenomena.
Imprecise or incomplete definitions
Most answers omitted that the elements were required to be in their 'standard states'.
Most Common Mistakes — Chemistry (9701)
Based on analysis of 11 official Cambridge examiner reports (2023, 2024, 2025). Avoid these errors to maximise your marks.
Imprecise curly arrows in organic mechanisms
Paper 2, Paper 4 · Criticised in every examiner report across all sessions (2021–2025)
Stating facts without explaining HOW or WHY
Paper 2, Paper 4 · Flagged in every examiner report as a Key Message
Imprecise or incomplete definitions
Paper 2, Paper 4 · Mentioned in every session across Papers 2 and 4
Using incorrect practical observation language
Paper 3, Paper 5 · Flagged every session in Paper 3 and Paper 5
Premature rounding and significant figure errors in calculations
Paper 2, Paper 3, Paper 4, Paper 5 · Every session, Papers 2, 3, 4, 5
Topics Students Struggle With Most
Electrophilic substitution mechanism
The single most poorly drawn mechanism across all sessions. Errors include: arrow not starting inside the ring, positive charge on sp³ carbon instead of inside the ring, second arrow starting on H instead of C–H bond, missing H⁺ product.
Paper 2, Paper 4
Nitrogen chemistry — basicity of amines and amides
Examiners report: 'The lack of basicity of an amide is due to the lone pair of electrons on the nitrogen atom being delocalised into the C=O group.' Also: 'attract a proton' is NOT equivalent to 'accept a proton' — the lone pair must FORM A COORDINATE BOND to a proton.
Paper 4
Period 3 reactions and properties (oxides and chlorides)
Candidates frequently mispredicted pH values: 'AlCl₃ was often omitted and considered to react with water to form a neutral solution.' NaCl is incorrectly described as acidic. SiCl₄ appearance at room temperature poorly known.
Paper 2
Lattice energy and Born-Haber cycles
Definition errors recur every session. Candidates confuse the direction of enthalpy arrows, use 'increases' instead of 'more exothermic', and make vague comparisons like 'BaSO₄ has greater attractions' without specifying which ions.
Paper 4
Kinetics — purpose of excess reagent and half-life evidence
Examiners: 'Many candidates did not understand that a large concentration was used to keep its concentration constant so that it did not affect the rate. A common error was to allow the reaction to go to completion.' Half-life claims without numerical evidence are not credited.
Paper 4
Buffer solutions — definition, pH calculation, and mechanism
Buffer definition must say 'resists changes in pH' not 'maintains constant pH'. At half-neutralisation, pH = pKa (because [acid] = [conjugate base]). Henderson-Hasselbalch errors include reversing acid and salt, and using wrong moles after acid/base addition.
Paper 4
Equilibrium — Le Chatelier's principle applied to novel situations
Candidates can state the principle but struggle to apply it to unfamiliar equilibria. Common errors: confusing 'amounts' with 'concentrations', ignoring physical states of reactants, and confusing equilibrium yield with rate.
Paper 2, Paper 4
Practical techniques — standard solution preparation and titration
Despite frequent testing, candidates struggle with: volumetric flask technique (stopper and invert to mix), when to rinse (beaker → flask = rinse; burette/pipette → flask = no rinse), and concordant titre selection (within 0.10 cm³).
Paper 3, Paper 5
Percentage error calculations
The uncertainty for instruments requiring TWO readings (balance, burette, thermometer) must be DOUBLED: e.g. burette = 2 × 0.05 cm³ = 0.10 cm³ total uncertainty. Balance = 2 × half-graduation. Few candidates apply this correctly.
Paper 3, Paper 5
Chemistry (9701) — Cambridge AS & A Level Full Archive 2002–2026
This page contains all 1793 available papers for Cambridge A Level Chemistry (9701) — 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 Chemistry (9701) 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, 9701_qp_12 is Paper 1, Variant 2.
Mark schemes for 9701 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.
