HKDSE M2 Drill Guide: One Paper, 150 Minutes, Algebra and Calculus
- 2026-10-09
TUTORZONE EXAM DRILL GUIDE · HKDSE M2 (ALGEBRA AND CALCULUS)
M2 is assessed exactly like M1: one paper of conventional questions, 100%, 2 hours 30 minutes, with Section A at 50 marks (8 to 12 elementary short questions) and Section B at 50 marks (3 to 5 long questions), all compulsory. The difference is that trigonometric formulas are provided for reference, since M2 is built on algebra and calculus.
What is in HKDSE M2?
Direct answer: M2 (Algebra and Calculus) is a single paper of conventional questions worth 100% in 2 hours 30 minutes. The framework states two sections with all questions compulsory: Section A (50 marks) of 8 to 12 elementary short questions and Section B (50 marks) of 3 to 5 long questions, and notes that trigonometric formulas are provided. There is no SBA.

Assessment at a glance (2027)
| Component | Content | Weighting | Duration |
|---|---|---|---|
| Section A · elementary short questions (50 marks) | The framework sets Section A at 50 marks in 8 to 12 elementary short questions, all compulsory | 50 分 | 55-60 min suggested |
| Section B · long questions (50 marks) | Section B is 50 marks in 3 to 5 long questions, all compulsory | 50 分 | 80-85 min suggested |
M2 losses follow a pattern: it is rarely ignorance but a fast algebra slip. So M2 drilling should include a specific routine – recompute every arithmetic error after each paper – which usually yields the most direct gain.
What each paper is actually testing
| Paper | Drill focus | How marks are lost |
|---|---|---|
| Section A · elementary short questions (50 marks) | Build speed in symbol manipulation: matrices, vectors, inequalities and sequences | An algebra slip that carries through the rest of the question |
| Section B · long questions (50 marks) | In proofs, justify each step; in calculus applications, define the variables first | Skipped steps in proofs and applications with no diagram or variable definition |
How should M2 preparation be ordered?
Direct answer: tools before applications: algebra, matrices and vectors first as the foundation, then limits and differentiation, then integration techniques such as substitution and partial fractions, and only then applications and proofs. Starting with applications usually bleeds marks on the manipulation.
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 |
How should proofs be written?
Direct answer: give a reason for every step – name the theorem, identity or definition – and keep the algebra tidy, one step per line. M2 proofs usually award a mark per step, so skipped steps lose marks even with the right result, while a wrong final conclusion can still keep most method marks if the key steps are there.
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: One full 150-minute timed paper a week, recomputing every manipulation error afterwards and drilling one weak question type.
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 · elementary short questions (50 marks) | 建議 55–60 分鐘 | About 5 min per question |
| Section B · long questions (50 marks) | 建議 80–85 分鐘 | 20-25 min per question; 10 min checking |
How should the 150 minutes be split?
Direct answer: about 55-60 minutes for Section A and 80-85 for Section B, with 10 minutes to check. Section B is mostly proofs and long applications whose thinking time is hard to predict, so the buffer belongs there; Section A should be drilled to mechanical speed.
The drilling mistakes that cost the most marks
| Mistake | What it looks like | What actually happens | Instead |
|---|---|---|---|
| Skipping algebra steps | Mental arithmetic over several lines | One mark per step, so skipped work loses marks | One step per line, naming the theorem or identity |
| Starting with applications | Avoiding proofs as too hard | Weak manipulation sinks the applications anyway | Matrices, vectors and differentiation first, then applications |
| Short of time in Section B | Chasing full marks in Section A | Section B is 50 marks and takes longer | Keep Section A to 55-60 minutes |
The error log and the mark scheme
Two columns: manipulation errors and concept errors. Recompute the first kind and record the failing step; only the second kind needs a return to the topic.
How many years should you drill?
M2 has been examined since 2012 with stable content; with less time do the latest five fully timed.
How many years of M2 past papers should you drill?
Direct answer: no official figure. M2 has been examined since 2012 and the content is stable, so every past paper fits the current syllabus; with less time sit the latest five fully timed, then take earlier years by type: matrices, vectors, differentiation, integration and proof.
Frequently asked questions
Must M2 trigonometric formulas be memorised?
The framework provides them for reference, so fluency in using them matters more than memorising.
How much harder is M2 than the Compulsory Part?
M2 is more abstract, being built on algebra and calculus, but its question types repeat heavily and respond well to drilling.
Is there an SBA in M2?
No. The framework sets the public examination at 100%.

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.
