How to get an A or A* in Cambridge IGCSE Accounting (0452)

Explain the transaction before recording it

For every transaction, identify what the business receives or gives up and which accounts are affected. Decide whether each item is an asset, liability, capital, income or expense. Then apply the debit and credit entries. This prevents the familiar mistake of treating every receipt as income.

Use a small imaginary business to practise a sequence of transactions. Record an owner’s investment, a credit purchase, a cash sale and a payment to a supplier. Follow how the balances change rather than learning each entry as an isolated trick.

Make adjustments visible and traceable

Give each adjustment its own working and label it clearly. For accruals and prepayments, ask which part of the expense belongs to the current accounting period. For depreciation, distinguish the period’s expense from accumulated depreciation and the carrying amount.

After completing a statement, check whether each adjustment has had every required effect. A correct expense figure can still leave an incomplete answer if the related asset or liability has been forgotten. Tick the adjustment only when you have accounted for both sides.

Use reconciliations to investigate differences

A reconciliation is a reasoned explanation of why two records differ. Identify whether an item belongs in the business’s records, in the reconciliation or elsewhere. Do not force the final balances to agree by inventing an unexplained figure.

For errors, identify what was recorded and what should have been recorded. Work out the correcting entry from that comparison. This is more reliable than memorising a list of error names while remaining unsure how to correct the accounts.

Interpret ratios with their context

Learn each required ratio as a relationship between quantities, not just a formula. Show the calculation with the appropriate units or form, then explain what the result indicates. A change in a ratio needs a comparison and a plausible explanation based on the information given.

Avoid treating a higher ratio as automatically better in every circumstance. Consider profitability, liquidity and the nature of the business. Check your exam-year syllabus for the required ratios because Cambridge has revised them for 2027–2029.

Keep presentation part of your checking routine

Use clear headings, dates and labels so another person can follow your answer. Keep workings close enough to identify which figures they support. If you make an arithmetic error, a visible method also makes it easier for you to diagnose and repair the underlying step.

Alternate multiple-choice reasoning with longer record-preparation tasks. After marking, classify errors as transaction analysis, adjustment, arithmetic or presentation. A balanced trial balance alone does not prove that every transaction was recorded correctly.
