A-Level Chemistry 9701 Drill Guide: Method, Drill Order and Pacing
TUTORZONE EXAM DRILL GUIDE · CAMBRIDGE A LEVEL CHEMISTRY 9701
Built on the Cambridge 9701 syllabus (2025-2027): Paper 2 (AS structured, 1 h 15 min, 60 marks, 46% of AS / 23% of A Level) is the main battleground, alongside Paper 1 (multiple choice, 1 h 15 min, 40 marks) and Paper 3 (practical skills, 2 hours, 40 marks); the A Level adds Paper 4 (A2 structured, 2 hours, 100 marks) and Paper 5 (planning, analysis and evaluation, 1 h 15 min, 30 marks). Method only: what each paper tests, the drill order, pacing, the usual mark losses, the error log and a 12-week timetable.
How is A-Level Chemistry 9701 assessed, and what does each part carry?
Paper 2 (AS structured questions): Structured questions, 60 marks (AS 46% / A Level 23%); Paper 1 (AS multiple choice): 40 multiple-choice questions, 40 marks (AS 31% / A Level 15.5%); Paper 3 (AS practical skills): Practical work and structured questions, 40 marks (AS 23% / A Level 11.5%); Paper 4/5 (A2 level): A2 structured 100 + planning 30 (A Level 38.5% / 11.5%)
Assessment at a glance (2027)
| Component | Content | Weighting | Duration |
|---|---|---|---|
| Paper 2 (AS structured questions) | Structured questions, 60 marks | AS 46% / A Level 23% | 1 h 15 min |
| Paper 1 (AS multiple choice) | 40 multiple-choice questions, 40 marks | AS 31% / A Level 15.5% | 1 h 15 min |
| Paper 3 (AS practical skills) | Practical work and structured questions, 40 marks | AS 23% / A Level 11.5% | 2 h |
| Paper 4/5 (A2 level) | A2 structured 100 + planning 30 | A Level 38.5% / 11.5% | 2 h / 1 h 15 min |
Eight questions for 60 marks in 1 h 15 min is about 8 minutes each. For calculations write the equation and formula first (n = m/M, c = n/V, q = mcT, Kc), then substitute, then give the unit; for explanations give the cause and then the consequence.
What each paper is actually testing
| Paper | Drill focus | How marks are lost |
|---|---|---|
| Paper 2 (AS structured questions) | equation and formula first, then numbers | Calculations drop the unit or the significant figures, equations are left unbalanced, and explanations stop at the conclusion instead of giving cause then effect |
| Paper 1 (AS multiple choice) | speed paper, sweep every question once | Too long on one hard stem, then guessing the last few; a cm^3 to dm^3 slip costs a mark the paper never gives back |
| Paper 3 (AS practical skills) | readings, sig figs, uncertainty | Readings are written without the instrument precision, the titration end point is misjudged, and uncertainty and significant figures ignore the printed instruction |
| Paper 4/5 (A2 level) | solid AS base first | At A2 the organic routes and electrochemistry are memorised rather than derived, and Paper 5 planning questions are never practised |
What is each A-Level Chemistry 9701 paper really testing, and what should you drill?
Paper 2 (AS structured questions): equation and formula first, then numbers; Paper 1 (AS multiple choice): speed paper, sweep every question once; Paper 3 (AS practical skills): readings, sig figs, uncertainty; Paper 4/5 (A2 level): solid AS base first
Drill order: by topic, then by year, then the mark scheme
| Step | What you do | Why |
|---|---|---|
| 1. By topic | Work through each topic, starting with the paper that allows least help (no calculator / closed book) | Exposes what is genuinely not understood |
| 2. By year | Whole papers to time, one or two a week | Trains pace, stamina and question selection |
| 3. Mark scheme | Go through the marking scheme question by question and log the scoring steps you missed | Most lost marks are written wrong, not thought wrong |
Should drilling go by topic first or by year?
By topic first, then whole papers by year, then the mark scheme. The first third of the time goes topic by topic (8-10 years of the same topic back to back), the middle switches to timed whole papers, and the last fortnight only redoes the recurring errors from your log.
A 12-week drilling timetable
| Week | Phase | What to do |
|---|---|---|
| Weeks 1-3 | By topic: foundation | Topic by topic, starting with the easiest marks, building habits and recall |
| Weeks 4-6 | By topic: core | 8-10 years of the same topic back to back, errors classified by topic |
| Weeks 7-8 | By topic: advanced and electives | Elective and higher-order topics, now under time pressure |
| Weeks 9-10 | By year: timed papers | One full paper a week, timed, no reference materials |
| Week 11 | Mark scheme work | Question by question against the marking scheme; list the scoring steps you omitted |
| Week 12 | Plug holes and simulate | Only the recurring errors from your log, then one full exam simulation |
Subject-specific weighting for this timetable: Chemistry runs in four blocks: quantities and structure, physical chemistry, inorganic and organic, then A2 extension. Weeks 1-3 redo the Paper 2 mole and stoichiometry questions, always writing equation, formula, substitution and unit as four steps. Weeks 4-6 take energetics, equilibria and kinetics, eight to ten years of the same topic back to back, until Kc, enthalpy and rate graphs are quick. Weeks 7-9 cover inorganic and organic structured questions and sit a full Paper 2 in 1 h 15 min. Week 10 practises the Paper 3 titration and readings, instrument precision, significant figures and uncertainty. Week 11 drills Paper 1 multiple choice, one full paper per sitting, sorting errors into concept, unit and misread. Week 12 redoes only the recurring error types, and only then adds Paper 4 and Paper 5.
Use it properly: this is not a checklist to finish. Every week must keep time for redoing errors, or from week 9 you will be repeating the same batch.
Pacing
| Paper | Time | Suggested split |
|---|---|---|
| Paper 2 (AS structured questions) | 1 h 15 min | about 8 min a question, 8 to check |
| Paper 1 (AS multiple choice) | 1 h 15 min | about 1.9 min a question |
| Paper 3 (AS practical skills) | 2 h | about 30 min a part |
| Paper 4/5 (A2 level) | 2 h / 1 h 15 min | A2 route only |
How should the time be split inside each A-Level Chemistry 9701 paper?
Paper 2 (AS structured questions): about 8 min a question, 8 to check; Paper 1 (AS multiple choice): about 1.9 min a question; Paper 3 (AS practical skills): about 30 min a part; Paper 4/5 (A2 level): A2 route only
The drilling mistakes that cost the most marks
| Mistake | What it looks like | What actually happens | Instead |
|---|---|---|---|
| Missing units | The number only | Loses every value mark | Add mol, dm^3, mol/dm^3 |
| cm^3 not converted | 25.0 multiplied by 0.100 directly | Concentration out by 1000x | 25.0 cm^3 = 0.0250 dm^3 |
| Wrong molar volume | 22.4 dm^3 used at r.t.p. | Gas volume all wrong | Use 24 dm^3/mol at room temperature |
| Bond energy not scaled | Subtracting 432 only once | Wrong sign and value | 2 mol HCl formed, so multiply by 2 |
| Conclusion only | ‘Because it is more reactive’ | Half marks at best | Give the cause (ionisation energy falls), then the effect |
The error log and the mark scheme
Four columns: equation and stoichiometry (was the equation balanced, was the mole ratio right), units and significant figures (cm^3 converted to dm^3, answer rounded as asked), explanation depth (cause and consequence, or just the conclusion) and data reading (titration end point, graph gradient, position of equilibrium). Only an error type that fills a cell three times deserves the last fortnight.
How many years should you drill?
Cambridge 9701 has official past papers for Papers 1-5 every session. Start with the last five years of Paper 2 and Paper 1 (AS content, the most stable shape), then add Paper 3; only A Level candidates need Paper 4 and Paper 5. The current syllabus covers the 2025-2027 sessions, so older sessions are best taken topic by topic rather than as whole-paper mocks. Five years is the minimum, and topic-by-topic drilling wants eight to ten.

Frequently asked questions
Is this page a mock paper or a drilling guide?
This is the A-Level Chemistry 9701 drilling guide: assessment structure, drill order, a 12-week timetable, pacing, common mark losses and the error-log method. For questions with answers, use the A-Level Chemistry 9701 mock papers linked under Related.
By topic or by year first?
By topic. Eight to ten years of the same topic back to back is what exposes repeating errors; going straight to whole papers just repeats the same batch under time pressure.
How should the error log be written?
Do not copy out questions. Per error record four things: question reference, which step failed (concept, wording, calculation), what the mark scheme requires, and the correct action next time.
If I sit only the AS Level, do I need Papers 4 and 5?
No. The AS Level is Paper 1 (40 marks), Paper 2 (60 marks) and Paper 3 (40 marks); Papers 4 and 5 belong to the A Level. If you plan to continue a year later, make sure the AS work on moles, energetics and equilibria is solid, because A2 electrochemistry and organic synthesis rest on it.
Should chemistry formulas be memorised or derived?
Both, but derive first. The four core relationships (n = m / M, c = n / V, q = mcT and the Kc expression) should be reproducible on blank paper before they become five-second recall. What separates candidates is the writing: equation, formula, substitution, unit, in that order. An answer with only the final number loses the method marks.
