HKDSE BAFS Paper 1: How to Drill Multiple Choice and Short Questions
TUTORZONE EXAM DRILL GUIDE · HKDSE BAFS PAPER 1
Paper 1 rewards what can be shown, not what can be memorised: the debit and credit side of every entry, the reason behind each cost classification, the benchmark behind every ratio. Multiple choice tests definitions and judgement, short questions test steps and explanation, and they need different drilling. This page sets out the order, a 12-week timetable and the error log.
How is HKDSE BAFS Paper 1 assessed, and what does each part carry?
Section A (multiple-choice): Compulsory Part; 17% of the subject mark (17%); Section B (three short questions): Compulsory Part; 8% of the subject mark (8%); Paper 2 (Elective Part, separate paper): 75% over 2 h 30 min: Section A 33%, Section B 27%, Section C 15% (one (75%)
Assessment at a glance (2027)
| Component | Content | Weighting | Duration |
|---|---|---|---|
| Section A (multiple-choice) | Compulsory Part; 17% of the subject mark | 17% | 30 min |
| Section B (three short questions) | Compulsory Part; 8% of the subject mark | 8% | 25-30 min |
| Paper 2 (Elective Part, separate paper) | 75% over 2 h 30 min: Section A 33%, Section B 27%, Section C 15% (one question) | 75% | 2 h 30 min |
Sixty minutes splits roughly 30 for the MC section and 25-30 for the three short questions. Accounting calculations such as depreciation, contribution and break-even carry both method and answer marks, so write every step.
What each paper is actually testing
| Paper | Drill focus | How marks are lost |
|---|---|---|
| Section A (multiple-choice) | Know the accounting equation and ratios; calculation marks are non-negotiable | Answers are guessed without doing the arithmetic first, so one wrong debit or credit side loses the whole item. |
| Section B (three short questions) | Both sides of every entry; show the working | Short questions give the final figure only, missing steps, the reason for the classification and the conclusion. |
| Paper 2 (Elective Part, separate paper) | This paper covers Paper 1 only | The elective is read from textbook examples only, never worked by hand, so presentation marks go. |
What is each HKDSE BAFS Paper 1 paper really testing, and what should you drill?
Section A (multiple-choice): Know the accounting equation and ratios; calculation marks are non-negotiable; Section B (three short questions): Both sides of every entry; show the working; Paper 2 (Elective Part, separate paper): This paper covers Paper 1 only
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: drill by question type. Start with multiple choice, marked but untimed; for every wrong item go back to the textbook definition and rewrite it in one sentence of your own.
Weeks 4-6: move to short questions with a fixed three-step answer: the working, the reason for the classification or judgement, then one concluding sentence. Mark against the scheme immediately and log which step was missing.
Weeks 7-9: timed whole papers. Warm up on the multiple choice, then hold each short question to its budget; only correct, never recopy.
Weeks 10-12: redo the recurring errors in the log, and give the elective its own slots so the statement formats and terminology are automatic before the exam.
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 (multiple-choice) | 30 min | about 30 min |
| Section B (three short questions) | 25-30 min | about 25-30 min |
| Paper 2 (Elective Part, separate paper) | 2 h 30 min | not covered here |
How should the time be split inside each HKDSE BAFS Paper 1 paper?
Section A (multiple-choice): about 30 min; Section B (three short questions): about 25-30 min; Paper 2 (Elective Part, separate paper): not covered here
The drilling mistakes that cost the most marks
| Mistake | What it looks like | What actually happens | Instead |
|---|---|---|---|
| One-sided entries | Debit only, or an amount with no double entry | Double entry must balance; a single side earns nothing | Write the debit, then the credit, then check they match |
| Forgetting residual value | Cost ÷ life | Residual value must come out first | Depreciation = (cost − residual) ÷ life |
| Wrong base for break-even | Using the price instead of the contribution | Break-even = fixed costs ÷ unit contribution | Work out the contribution first |
| Reconciliation direction | Adding unpresented cheques to the bank balance | They make the bank balance too high, so they are deducted | Decide which book has not yet recorded the item |
The error log and the mark scheme
One question type per page, three columns: (1) the question and its unit; (2) the failing action, whether that was reversing debit and credit, omitting the reason for a classification, or computing a ratio without comparing it; (3) the wording to reuse next time, for example “write Dr receivables, Cr sales, then a separate sentence for the allowance rationale”. Three hits in one column and that wording should need no thought.
How many years should you drill?
The BAFS syllabus has been revised, so older papers do not always match the current unit names or statement formats. Check question types and weighting against current-syllabus papers and the official specimen first, then work back through three to five years of matching questions. Where years are thin, lean on school mocks and questions you build yourself.

Frequently asked questions
Is this page a mock paper or a drilling guide?
This is the HKDSE BAFS Paper 1 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 HKDSE BAFS Paper 1 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 my accounting is weak, should I get tutoring or start drilling Paper 1?
Build the skeleton first. Spend a week getting the accounting cycle, the classifications and the statement formats straight, then drill; drilling before that just fills the error log with the same mistake.
Should I memorise model answers for the short questions?
Memorise sentence patterns, not answers. Learn a few classification sentences and a few ratio comparison sentences, then pour the numbers the question gives you into them; memorised figures are useless the moment the question changes.

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.
