Calculator Policy

Use only calculators on the HKEAA Approved List, bearing the 'H.K.E.A.A. APPROVED' (or older 'H.K.E.A. APPROVED') label. Programmable scientific models (e.g. Casio fx-50FH II, fx-3650P II) are allowed, and you MAY keep your own formulas/programs stored in memory — HKDSE does not require you to clear it. Graphic-display (graphing) and CAS/symbolic calculators are not on the approved list and must not be used.

  • AO1: To demonstrate knowledge and understanding of business concepts and accounting principles. (40%)
  • AO2: To apply such knowledge and understanding to solve problems in various business contexts. (35%)
  • AO3: To analyse and evaluate business issues and financial statements for decision-making. (25%)

Tips & Strategies

The Real Battleground: Where Marks Hide in BAFS

In HKDSE BAFS, top scorers aren't just those who memorize formulas; they are the candidates who master accounting principles and apply business theories to specific real-world contexts. Many students lose critical marks not because of a lack of knowledge, but due to structural and conceptual slips. Understanding the examiner's mindset is your biggest asset on exam day.

The 5-Minute Habit: Managing Time Across Papers

Time management is the ultimate divider between a Level 5** and a Level 4 candidate. For Paper 1 (Compulsory Part), you have only 60 minutes for 72 marks. This requires a rapid, highly disciplined pace:

  • Section A (MCQs): Spend no more than 1.5 minutes per question (36 minutes total).
  • Section B (Short Qs): Allocate 8 minutes per 8-mark question. Use the remaining 4 minutes for a final sweep.

For Paper 2A (Accounting Elective), you have 150 minutes for 88 marks. This gives you roughly 1.7 minutes per mark. Spend the first 5 minutes scanning the entire paper to assess the complexity of the ledger adjustments and final accounts before putting pen to paper.

Cracking Command Words: Explaining vs. Listing

Examiner reports repeatedly highlight a common pitfall: candidates fail to adapt their answers to command words. Here is the golden rule for structuring written responses:

  • 'Identify' or 'State': Provide only the name of the principle or term (e.g., 'Going Concern Concept'). No elaboration is required.
  • 'Explain': State the point, then link it logically to the consequence. For example, when discussing the Prudence concept, explain that assets/profits must not be overstated, and liabilities/losses must not be understated, so as to protect stakeholders.
  • 'Illustrate with examples' / 'With reference to the context': Generic answers will be penalized. If the question mentions Candy's skincare business, your answer must explicitly refer to her inventory of olive oil skincare products, not generic goods.

What Top Scorers Do Differently

High achievers separate themselves in two main areas: structural accuracy in financial statements and precision in cost accounting.

1. Perfect Ledger Preparation

Never balance off accounts before recording all adjusting entries. When dealing with partner admission or dissolution, always create a revaluation account first to determine the profit or loss sharing before updating the capital accounts. Additionally, ensure that revaluation fees are written off as expenses rather than added to revaluation gains.

2. Multi-Product CVP Clarity

In cost accounting, when calculating the breakeven point for multi-product scenarios, top scorers calculate the contribution margin based on the sales mix ratio rather than computing individual product breakeven points in isolation. This distinction is critical for gaining full marks in Paper 2A's structured questions.

Calculator Programmes

Gross Profit Margin

Casio fx-50FH II / fx-3650P II (HKEAA-approved programmable)

Purpose: \(\text{GP margin}=\dfrac{\text{gross profit}}{\text{net sales}}\times100\%\).

When to use it: Profitability analysis.

Steps
Prompt gross profit, net sales; outputs the margin %.
Program
?→G:?→S:G÷S×100

Exam note: Use net sales (after returns), not gross sales.

Current Ratio

Casio fx-50FH II / fx-3650P II (HKEAA-approved programmable)

Purpose: \(\text{Current ratio}=\dfrac{\text{current assets}}{\text{current liabilities}}\).

When to use it: Short-term liquidity analysis.

Steps
Prompt current assets, current liabilities; outputs the ratio.
Program
?→A:?→L:A÷L

Exam note: Expressed as a ratio (e.g. 2 means 2:1).

Straight-line Depreciation

Casio fx-50FH II / fx-3650P II (HKEAA-approved programmable)

Purpose: \(\text{annual dep.}=\dfrac{\text{cost}-\text{residual}}{\text{useful life}}\).

When to use it: Depreciation schedules.

Steps
Prompt cost, residual, life; outputs annual depreciation.
Program
?→C:?→R:?→N:(C-R)÷N

Exam note: Residual (scrap) value is subtracted before dividing.

Common Mistakes

  1. 1highMarks at stake: 2Hong Kong Business Environment

    Confusing the objective of WTO, incorrectly believing that it 'eliminates' trade barriers rather than 'lowering' them.

    How to avoid it: Remember that WTO aims to reduce and lower tariff and non-tariff trade barriers gradually, not to fully eliminate them instantly.
  2. 2highMarks at stake: 4Cost Accounting for Decision-making

    Calculating CVP breakeven sales volume at the individual product level instead of the overall company level for multi-product scenarios.

    How to avoid it: Use the sales mix ratio to calculate the weighted average contribution margin per unit, then divide fixed costs by this weighted average to find the overall breakeven point.
  3. 3mediumMarks at stake: 3Accounting for partnership

    Omitting the transfer of realization expenses to the capital accounts of partners upon partnership dissolution.

    How to avoid it: In partnership dissolution, ensure all liquidation and realization expenses are debited to the Realisation Account and subsequently distributed to partners' capital accounts in their profit-sharing ratio.
  4. 4mediumMarks at stake: 2Accounting for partnership

    Including professional valuation fees as part of revaluation gains rather than writing it off as an expense in the revaluation process.

    How to avoid it: Treat valuation fees as an administrative expense in the Profit and Loss Account; do not add or subtract them from the carrying value adjustments of the asset.
  5. 5lowMarks at stake: 2Trial balance

    Mistaking 'Loans to Employees' as a liability in the Trial Balance and placing it in the credit column.

    How to avoid it: Classify 'Loans to Employees' as an asset (other receivables) and place it in the debit column of the Trial Balance.
  6. 6highMarks at stake: 2Accounting Assumptions, Principles and Conventions

    Using liquidation values instead of historical cost or carrying book value for equipment, failing to apply the 'Going Concern' concept correctly.

    How to avoid it: Unless the company is actively preparing to wind up, always value assets based on historical cost less accumulated depreciation under the Going Concern assumption.
