HKDSE Maths Paper 2 (Multiple-choice): 75-Minute Pacing and Three Speed Methods
TUTORZONE EXAM DRILL GUIDE · HKDSE MATHS PAPER 2 (MC)
Paper 2 is only 35% of the grade but only 1 hour 15 minutes (75 minutes) long – the heaviest time pressure in the subject: the same content that gets 2 h 15 min in Paper 1 gets 75 minutes here. So drilling Paper 2 is not about whether you can do the questions, but how to finish in 75 minutes while protecting the foundation marks.
How many questions are in HKDSE Maths Paper 2?
Direct answer: the HKEAA 2027 HKDSE Mathematics Assessment Framework states only that Paper 2 has Section A (two-thirds of the paper mark) and Section B (one-third), all compulsory, and does not publish a question count. So a fixed ’45 questions’ is not part of the framework; pace by minutes per section instead.
Assessment at a glance (2027)
| Component | Content | Weighting | Duration |
|---|---|---|---|
| Section A (foundation) | Two-thirds of the paper mark; foundation topics of the Compulsory Part plus S1-S3 foundation topics; all MC compulsory | 全卷 2/3 | 45-50 min suggested |
| Section B (with non-foundation) | One-third of the paper mark, adding non-foundation S1-S3 topics | 全卷 1/3 | 20-25 min suggested |
| Whole paper (context) | The framework states the sections and their shares but does not publish a question count, so pace by minutes, not by a memorised number of questions | 35% | 1 h 15 min |
Paper 2 has the tightest pacing in the subject: about 0.47 percentage points a minute (35% over 75 minutes), against 0.48 in Paper 1 where you can work more slowly. So the skill to train is selection: which items must be right, and which should be abandoned.
What each paper is actually testing
| Paper | Drill focus | How marks are lost |
|---|---|---|
| Section A (foundation) | Target zero loss: this section sets your floor, so drill to 90%+ accuracy | Deriving slowly on easy items; one sticky question slowing the rest |
| Section B (with non-foundation) | Take your strongest items first and eliminate options by estimation and substitution | Spending 5+ minutes on one hard item and leaving the last three blank |
| Whole paper (context) | Time every attempt and note the question where you started to rush | Never timing, then discovering in the hall that you cannot finish |
How should the 75 minutes be split?
Direct answer: in three blocks: the first 45-50 minutes for Section A (two-thirds of the marks and the block you cannot afford to lose); the next 20-25 minutes for Section B; the final 5 minutes for the answer sheet and any skipped questions. If an item resists you for more than two minutes, flag it and move on.
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 |
What are the three speed methods?
Direct answer: (1) back-substitution – put the options into the condition, which beats forward derivation; (2) magnitude estimation – judge the order of magnitude or sign and eliminate two or three options; (3) sketches and special values – a quick graph, or 0, 1 and symmetry. These are legitimate MC-only shortcuts and are not allowed as working in Paper 1.
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: Two 75-minute timed Paper 2 sessions a week, and after each one note the question where you first started rushing. When that number falls, you are improving.
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 |
|---|---|---|
| Section A (foundation) | 建議 45–50 分鐘 | About 45-50 of the 75 minutes |
| Section B (with non-foundation) | 建議 20–25 分鐘 | About 20-25 min; last 5 min for the answer sheet |
| Whole paper (context) | 1 小時 15 分鐘 | 75 minutes total; keep 5 for checking |
Section A or Section B first?
Direct answer: Section A. It carries two-thirds of the paper and is built on foundation topics, so it is the block that must not be lost; banking it secures your floor even if Section B contains hard items. Do not march through in question order and get stuck in the middle.
The drilling mistakes that cost the most marks
| Mistake | What it looks like | What actually happens | Instead |
|---|---|---|---|
| Drilling Paper 2 untimed | Working slowly as if practising topics | The paper cannot be finished in the hall and the last items stay blank | Time every Paper 2 attempt at 75 minutes |
| Fighting one hard item | Spending five or more minutes on one question | The foundation items behind it suffer more | Flag and skip after two minutes, return at the end |
| No answer-sheet check | Handing in straight away | Blanks and skipped items are never recovered | Keep the final five minutes for the answer sheet |
The error log and the mark scheme
For Paper 2, log the topic and the seconds it took. A topic is only mastered when the time falls (say 90 to 60 seconds) while the answer stays correct.
How many years should you drill?
Paper 2 question types are stable and ten years covers most topics; sit the latest five fully timed and pull earlier years by topic.
Arithmetic slips are my biggest problem – what helps?
Direct answer: treat them as a separate topic: record whether each slip was a sign, a bracket, a unit or a rounding issue, then redo that type under time pressure. Paper 2 slips usually come from rushing rather than ignorance, so practise fast and accurate rather than simply faster.
Frequently asked questions
May I use a calculator?
Yes – HKEAA allows an electronic calculator and mathematical drawing instruments.
Does Paper 2 provide formulas?
Some are provided, but the common formulas and identities must be known cold or 75 minutes will not be enough.
What should I do with a skipped question?
Mark the most likely option on the answer sheet and flag the question, then return in the final five minutes.

Next step: find a tutor / register as a tutor
After drilling, the hard part is telling a conceptual error from a writing error. Tell us the year group, the school and your available times, and TutorZone will match you with a tutor who knows the HKEAA assessment requirements.
Demand for tutors in this subject is steady, and those who can explain the marking scheme and where marks are won are especially sought after. Register free; you pay only when a match succeeds.
