Cambridge 0452 and 0985 · Sub-topic 3.1
The trial balance
The 3 skills the syllabus asks for, the slips that cost marks, and how our teachers explain it.
What students must be able to do
- Explain the purpose and limitations of a trial balance.
- Prepare a trial balance from a list of balances and amend one containing errors.
- Identify the six errors that do not affect a trial balance: commission, compensating, complete reversal, omission, original entry and principle.

How our teachers teach it
A trial balance proves only that total debits equal total credits, nothing more. Our teachers teach the six errors it cannot reveal as a set, each with its own tiny example, because Paper 1 questions test exactly that distinction. For preparation questions we teach a column-by-column routine, so no balance is placed on the wrong side.
Mini-example: listing the balances
A new business has these closing balances: equipment RM12,000, inventory RM5,000, bank RM6,000 and receivables RM2,000 (all debit balances), against capital RM20,000 and payables RM5,000 (credit balances).
Debit total: 12,000 + 5,000 + 6,000 + 2,000 = RM25,000. Credit total: 20,000 + 5,000 = RM25,000. The columns agree, which is the arithmetic check a trial balance provides.
Now suppose a RM200 credit sale was never recorded. The trial balance still agrees, because neither the debit to receivables nor the credit to sales was made. This is an error of omission, one of the six errors the syllabus lists as invisible to the trial balance. A balanced total proves matching columns, not correct books.
A different slip does show up: if the bank balance (an asset, so a debit) is written in the credit column, the totals differ by twice RM6,000. The cure is a column-by-column routine: asset and expense balances on the debit side, liability, capital and income on the credit side.
If any of these slips sound familiar, we can help. A teacher can mark your child's answers on the trial balance line by line and show where the marks go. Book a trial class.
Unchanged between 2026 and 2027
The official wording of this sub-topic is essentially the same in both syllabuses, so students on either version can prepare in the same way.
Where it is examined
The trial balance can appear in either paper, as a short question or as part of a longer task. Cambridge bases both papers on the whole syllabus. See the guides to Paper 1 and Paper 2 for the format.
