GCE A/L Accounting common mistakes
GCE A/L Accounting · Understand the traps and how to avoid them.
When preparing a statement of financial position, candidates add the draft profit to the opening capital instead of the adjusted profit after corrections, or they omit drawings and the closing capital reconciliation entirely.
Correction-of-errors questions often give a trial balance that already balances, so candidates assume the profit figure is final and never rebuild it. They also treat drawings as an expense in the income statement rather than a deduction from capital, because the double entry (Dr Capital, Cr Drawings) is learned mechanically without linking it to the capital account format.
What to do instead
Always produce a working: opening capital + additional capital introduced + adjusted net profit − drawings = closing capital, and post every correction through the profit figure before it enters that working. Mark each correction as affecting profit only, capital only, or both (e.g. an overcast purchase affects profit; drawings affect capital only). Reconcile the resulting capital figure to the statement of financial position total before moving on.
Candidates treat a revaluation surplus as income in the statement of profit or loss, or they depreciate the revalued asset on original cost in the year of revaluation and subsequent years.
The revaluation model is taught alongside the cost model, and candidates conflate the two. The idea that a gain bypasses profit or loss and goes to other comprehensive income (or a revaluation reserve) feels counterintuitive when the asset is still held and no cash has moved, so candidates default to the familiar 'gain = income' pattern.
What to do instead
Memorise the rule as a decision tree: increase above carrying amount → other comprehensive income and accumulated in equity (revaluation surplus); decrease reversing a prior surplus on the same asset → other comprehensive income; all other decreases → profit or loss. After revaluation, recompute depreciation on the new carrying amount over the remaining useful life, and transfer the excess depreciation (revaluation surplus amortisation) from revaluation reserve to retained earnings if the exam's convention requires it. Show the revaluation reserve movement as a separate line in the statement of changes in equity.
In partnership questions, candidates admit or retire a partner without revaluing the assets, or they calculate goodwill and credit the full amount to the retiring partner's capital account instead of sharing the adjustment between continuing partners through the old and new profit-sharing ratios.
Goodwill is the least intuitive adjustment: candidates see the retiring partner 'deserving' the goodwill and forget that the continuing partners are effectively buying that share. Revaluation is skipped because candidates copy the admission template and forget that the revaluation gain or loss must be shared in the old ratio before the new partner is admitted.
What to do instead
Use a fixed sequence for every admission/retirement: (1) revalue assets and share the gain/loss in the old ratio; (2) raise goodwill and share it in the old ratio; (3) write off goodwill against the new ratio (or record the purchase of the retiring partner's share); (4) admit or remove the partner and record capital introduced or paid out; (5) restate the profit-sharing ratio. Show each step as a separate column so the marker can see the ratio used.
Candidates prepare a bank reconciliation by adjusting the cash book for unpresented cheques and deposits not yet credited, or they adjust the bank statement balance for items that belong in the cash book.
Both documents are 'about cash', so candidates apply corrections to whichever balance they are holding at the time. The direction of each adjustment (add or deduct) is also memorised as a list rather than derived, so a small change in wording flips the sign.
What to do instead
Sort every item into one of two buckets first: items already in the cash book but not the bank statement (unpresented cheques, uncredited lodgements, bank errors) go to the bank reconciliation; items on the bank statement not yet in the cash book (bank charges, interest, standing orders, direct credits, dishonoured cheques) go to the cash book. Then derive the sign by asking 'what would the bank statement show if this cleared?'. Present the reconciliation as: balance per bank statement + lodgements not credited − unpresented cheques ± bank errors = balance per adjusted cash book.
Candidates open a suspense account and leave the balance unexplained, or they clear it by posting the difference to a nominal 'suspense' expense rather than correcting the underlying error.
When a trial balance fails to agree, the suspense account is the quickest way to make it balance, and candidates stop there. They also confuse errors that affect the trial balance (one-sided entries, transposition, omission of one side) with errors that do not (errors of principle, compensating errors, complete omission), so they post corrections that create new imbalances.
What to do instead
Classify every error before correcting it: does it affect the agreement of the trial balance? Only one-sided, transposition, and addition errors do. For each, write the journal with both sides explicitly and state which account the suspense entry clears. Finish by proving the suspense account to nil and re-extracting the trial balance. If a suspense balance remains, treat it as a red flag and find the missing entry rather than writing it off.
In incomplete-records questions, candidates compute the purchases figure from the bank payments to suppliers without adjusting for opening and closing payables, or they use the gross profit margin and mark-up interchangeably.
Mark-up and margin are both percentages of profit, but on different bases (cost vs sales), and candidates grab whichever formula they remember. The payables control account is often skipped because candidates go straight to the cash book, ignoring credit transactions and the opening/closing balances.
What to do instead
Write the formula before substituting: mark-up = gross profit / cost of sales; margin = gross profit / sales. Convert explicitly (margin = mark-up / (1 + mark-up)) and label the base in the working. Build purchases through the payables control account: opening payables + purchases − payments − discounts received = closing payables. Then close the loop: opening inventory + purchases − closing inventory = cost of sales, and check it against sales × (1 − margin).
Candidates record a debenture issue as a share issue, crediting share capital and share premium, or they omit the accrued debenture interest and the tax treatment of interest from the finance cost line.
Both are long-term finance raised by the company, and the journal for each starts with a debit to bank, so the distinction blurs. Debenture interest is also often paid half-yearly, and candidates forget to accrue the unpaid half-year, understating the finance cost and the liability.
What to do instead
Fix the journal in memory: debenture issue → Dr Bank, Cr Debentures (liability); share issue → Dr Bank, Cr Share Capital at nominal value, Cr Share Premium for the excess. For interest, accrue the full period charge regardless of payment dates: Dr Finance Cost, Cr Debenture Interest Payable (or Bank if paid). Present debentures separately from equity in the statement of financial position, and show interest as a finance cost before tax, not as an appropriation of profit.
In standard costing, candidates calculate the material price variance using actual quantity purchased when the exam requires quantity used, or they mix up the labour rate and labour efficiency variances and report adverse variances as favourable.
The formulas look symmetric, so candidates learn them as a list without the underlying logic. The sign convention (adverse when actual cost or usage exceeds standard) is also easy to invert when the numbers are close, and candidates rarely check their answer against a common-sense reading of the situation.
What to do instead
Derive each variance from a labelled diagram: standard quantity × standard price, actual quantity × standard price, actual quantity × actual price; the gap between adjacent boxes is the variance. State the formula and the sign convention at the top of the answer. After computing, sanity-check the direction: if actual price or usage is higher than standard, the variance is adverse. For material price, confirm whether the syllabus convention uses quantity purchased or used and apply it consistently.
When preparing a cash budget, candidates include depreciation, bad debts written off, and other non-cash items as cash outflows, or they record credit sales in the month of sale rather than the month of receipt.
The budget is built from the income statement figures, and candidates carry over every expense line without asking whether cash moves. Receipts timing requires reading the credit terms carefully, and candidates default to the sales month because it is the first column they see.
What to do instead
Before building the budget, list every item as cash or non-cash and strike out depreciation, provisions, and accruals that do not settle in the period. For receipts, apply the credit terms explicitly: month of sale × percentage paid in that month, month + 1 × percentage paid the following month, and so on, with a separate line for irrecoverable amounts. Show a workings column so the marker can trace each receipt to its sales month.
In ratio analysis questions, candidates compute ratios and stop, without interpreting them, comparing them to a prior year or industry benchmark, or linking them to the business context given in the scenario. They also mix up return on capital employed with return on equity and use closing rather than average figures where the convention requires averages.
Candidates treat ratio questions as calculation exercises because the marks look numerical, and they run out of time before the interpretation. The distinction between ROCE (operating profit / capital employed) and ROE (profit after tax / equity) is blurred, and average-versus-closing is rarely stated in the question, so candidates pick arbitrarily.
What to do instead
Structure the answer as: calculate, compare, explain, conclude. For each ratio, state the formula, the result, the movement against the comparator, and one business reason for the movement drawn from the scenario. Use average balances for return and turnover ratios where opening and closing figures are both given, and state that you have done so. Keep ROCE and ROE separate and define capital employed explicitly (total equity + non-current liabilities, or total assets − current liabilities).
