DSE Mathematics Paper 2: Multiple-Choice Timing and Triage
Marks in the multiple-choice paper are won by triage
Paper 2 is multiple choice throughout, and the clock bites harder than the content: Section A carries about two-thirds of the marks, Section B one-third, and one stuck question drags the rest down. Fix a three-pass rhythm before the bell: obvious items first, written calculation second, hard items and review last.
How is DSE Mathematics Paper 2 assessed, and what does each part carry?
Section A: Questions carrying two-thirds of the paper mark; foundation topics of (~2/3); Section B: Questions carrying one-third of the paper mark; Compulsory Part plus f (~1/3)
Assessment at a glance (2027)
| Component | Content | Weighting | Duration |
|---|---|---|---|
| Section A | Questions carrying two-thirds of the paper mark; foundation topics of the Compulsory Part and S1-S3 | ~2/3 | 45-48 min |
| Section B | Questions carrying one-third of the paper mark; Compulsory Part plus foundation and non-foundation S1-S3 | ~1/3 | 25-27 min |
Thirty questions in 75 minutes is about 1.5 minutes each, so skipping fast is the core skill: three minutes on one item costs you two others. Mark answers straight onto the answer sheet rather than transcribing twice.
What each paper is actually testing
| Paper | Drill focus | How marks are lost |
|---|---|---|
| Section A | 1-1.5 min per item; recall and concept, not long computation | Stuck in Section A past two minutes, with everything after it rushed. |
| Section B | Do the ones you know first; flag and skip anything with no route after two minutes | Section B working skipped, leaving no way to locate the error on review. |
What is each DSE Mathematics Paper 2 paper really testing, and what should you drill?
Section A: 1-1.5 min per item; recall and concept, not long computation; Section B: Do the ones you know first; flag and skip anything with no route after two minutes
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: Weeks 1-3: a question-type list, grouping five years of Section A items by topic and writing the fastest method for each.\nWeeks 4-6: timed sets of fifteen questions in twenty minutes, stopping dead at the bell and logging whether the overrun was calculation or reading.\nWeeks 7-9: three-pass runs, obvious items only in pass one, a four-minute cap in pass two, review of answered items in pass three.\nWeeks 10-12: two full papers a week, alternating with written calculation practice.
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 | 45-48 min | 45-48 min (aim 80%+) |
| Section B | 25-27 min | 25-27 min plus 5 min checking |
How should the time be split inside each DSE Mathematics Paper 2 paper?
Section A: 45-48 min (aim 80%+); Section B: 25-27 min plus 5 min checking
The drilling mistakes that cost the most marks
| Mistake | What it looks like | What actually happens | Instead |
|---|---|---|---|
| Three minutes on one item | “Let me try once more” | It costs the two items behind it; Paper 2 is a speed paper | No route after two minutes: flag, skip, return |
| Working on the question paper | Computing on the stem | Transcription errors and double the time | One key step on rough paper, answer straight to the sheet |
| Ignoring the options | Full working every time | MC allows substitution, estimation and elimination | Read the options first: many items only need a range or a substitution |
The error log and the mark scheme
Three columns: the question and the option chosen; the first move the correct method needs; whether the loss was conceptual, arithmetic or comprehension. Copy the exact wording missed on comprehension slips.
How many years should you drill?
Section A recycles question types heavily, so five years covers most of it, while Section B non-foundation items change their packaging and are better drilled by topic.
How many years of past papers is enough?
Section A recycles question types heavily, so five years covers most of it, while Section B non-foundation items change their packaging and are better drilled by topic.
Frequently asked questions
Is this page a mock paper or a drilling guide?
This is the DSE Mathematics Paper 2 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 DSE Mathematics Paper 2 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.
Should working be written for multiple choice?
Only the answer is marked, but working beside the question is what makes review possible, and mental shortcuts are the main source of error.
What should the last minutes be spent on?
Uncertain items and calculations first, then changed answers; re-reading settled questions wastes the review window.

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.
