1. Mock Paper Overview | 模拟卷概览
This mock paper simulates a typical AS Unit test, covering both financial and management accounting topics in line with the OCR specification. It includes ten structured questions that test definitions, calculations, journal entries, and the preparation of financial statements. Total marks are set at 60, and students should allocate approximately 1.5 minutes per mark.
该模拟卷模拟了典型的AS单元测试，涵盖OCR考纲中的财务会计与管理会计主题。试卷包含十道结构化题目，测试定义、计算、日记账分录和财务报表编制。总分设为60分，考生应分配约每分1.5分钟的作答时间。
2. Question 1 – Adjusting for Prepayments & Accruals | 问题1 – 预付与应计调整
A business paid an annual insurance premium of £2,400 on 1 April 20X4. Its financial year ends on 30 September 20X4. To apply the accruals concept, we must match the expense to the period benefited. Six months (April–September) relate to the current year: £2,400 × 6/12 = £1,200 expense. The remaining £1,200 is a prepayment. The adjusting journal removes the prepaid portion from insurance expense: Dr Prepaid Insurance (current asset) £1,200, Cr Insurance Expense £1,200. Failure to record this would overstate expenses and understate profit.
某企业于20X4年4月1日支付年度保险费£2,400，会计年度截止于20X4年9月30日。根据应计概念，费用必须与服务受益期相匹配。六个月（4月至9月）归属本年度：£2,400 × 6/12 = £1,200费用，剩余£1,200为预付费用。调整分录将预付部分从保险费中转出：借 预付保险费（流动资产）£1,200，贷 保险费费用 £1,200。若遗漏该分录，将导致费用高估、利润低估。
3. Question 2 – Depreciation: Straight-Line vs Reducing Balance | 问题2 – 折旧方法：直线法与余额递减法
A machine costs £20,000 with an estimated residual value of £2,000 and a useful life of 5 years. Under the straight-line method, annual depreciation is:
Annual Depreciation = (Cost − Residual Value) / Useful Life = (£20,000 − £2,000) / 5 = £3,600
This gives a constant charge each year. In contrast, the reducing balance method uses a fixed percentage, say 30%, applied to the net book value. Year 1 charge: £20,000 × 30% = £6,000; Year 2: (£20,000 – £6,000) × 30% = £4,200. The reducing balance method front-loads depreciation, lowering profit earlier and being more prudent for assets that lose value quickly.
一台机器成本£20,000，预计残值£2,000，使用年限5年。直线法下，年折旧额计算为：
年折旧额 = (成本 − 残值) / 使用年限 = (£20,000 − £2,000) / 5 = £3,600
该方法每年计提等额费用。而余额递减法使用固定百分比，例如30%，基于账面净值计算。第一年费用：£20,000 × 30% = £6,000；第二年：(£20,000 – £6,000) × 30% = £4,200。余额递减法在前几年计提更多折旧，降低早期利润，对价值快速下降的资产更为谨慎。
4. Question 3 – Bad Debts and Provision for Doubtful Debts | 问题3 – 坏账与呆账准备金
A business has trade receivables of £80,000 at year-end. It estimates that 5% may not be collected and currently holds an allowance of £2,800. The required allowance is £80,000 × 5% = £4,000. Since the existing allowance is £2,800, an increase of £1,200 is needed. The adjusting entry is: Dr Irrecoverable Debts Expense £1,200, Cr Allowance for Doubtful Debts £1,200. If a specific debt is later written off, we would Dr Allowance, Cr Trade Receivable without hitting the income statement again, provided the allowance is adequate.
某企业年末应收账款余额为£80,000。估计5%可能无法收回，当前准备金余额为£2,800。所需准备金为£80,000 × 5% = £4,000。因已有£2,800，需调增£1,200。调整分录为：借 坏账费用 £1,200，贷 呆账准备金 £1,200。若后续实际核销某笔具体债务，只要准备金足够，应借记准备金、贷记应收账款，不再重复冲击损益表。
5. Question 4 – Bank Reconciliation Statement | 问题4 – 银行存款调节表
The cash book shows an overdraft of £3,500, while the bank statement shows an overdraft of £3,200. Reconciling items: unpresented cheques totalling £500 (already deducted in cash book), and bank charges of £200 not yet recorded. Updated cash book: start with overdraft (£3,500) and deduct bank charges = £3,700 overdraft. The bank reconciliation then adjusts the bank statement balance: overdraft per bank statement (£3,200) less unpresented cheques (£500) = £3,700 overdraft. Now both figures match, confirming accuracy. Common mistake: forgetting to update the cash book before reconciling.
现金账簿显示透支£3,500，银行对账单显示透支£3,200。调节项目：未兑现支票合计£500（现金账簿已扣减），以及尚未入账的银行手续费£200。更新后现金账簿：起始透支£3,500，扣减银行手续费后为透支£3,700。银行调节表对银行余额进行调整：银行对账单透支£3,200减去未兑现支票£500，得到透支£3,700。两者一致，确认无误。常见错误：在调节前忘记更新现金账簿。
6. Question 5 – Income Statement Preparation | 问题5 – 利润表编制
Given an unadjusted trial balance and year-end adjustments, the income statement for the year ended 30 September 20X4 is prepared. Revenue: £180,000; opening inventory: £12,000; purchases: £95,000; closing inventory per physical count: £15,000. Cost of sales = opening inventory + purchases – closing inventory = £12,000 + £95,000 – £15,000 = £92,000. Gross profit = £180,000 – £92,000 = £88,000. Adjust for operating expenses: wages £28,000 + accrual £800 = £28,800; rent £6,000 – prepaid £300 = £5,700; insurance expense per prepayment adjustment £1,200; depreciation £3,600. Total expenses = £28,800 + £5,700 + £1,200 + £3,600 = £39,300. Net profit = £88,000 – £39,300 = £48,700.
根据未调整试算平衡表和期末调整，编制截至20X4年9月30日的利润表。收入£180,000；期初存货£12,000；采购£95,000；期末存货盘点£15,000。销售成本 = 期初存货 + 采购 – 期末存货 = £12,000 + £95,000 – £15,000 = £92,000。毛利= £180,000 – £92,000 = £88,000。调整营业费用：工资£28,000 + 应计£800 = £28,800；租金£6,000 – 预付£300 = £5,700；保险费按预付调整后为£1,200；折旧£3,600。费用合计=£39,300，净利润= £88,000 – £39,300 = £48,700。
7. Question 6 – Statement of Financial Position Adjustments | 问题6 – 财务状况表调整
The statement of financial position as at 30 September 20X4 reflects all adjustments. Non-current assets: machinery at cost £20,000 less accumulated depreciation £3,600 = £16,400. Current assets: closing inventory £15,000, trade receivables £80,000 less allowance £4,000 = £76,000, prepaid insurance £1,200, prepaid rent £300, bank overdraft (£3,700). Total current assets less overdraft = £88,800. Capital: opening balance + net profit – drawings. Current liabilities: trade payables £22,000, accrual for wages £800. The statement balances when total assets equal total equity and liabilities. Students must classify assets correctly and net off the overdraft.
截至20X4年9月30日的财务状况表反映所有调整。非流动资产：机器成本£20,000减去累计折旧£3,600 = £16,400。流动资产：期末存货£15,000，应收账款£80,000减准备金£4,000 = £76,000，预付保险费£1,200，预付租金£300，银行透支(£3,700)。流动资产合计减去透支为£88,800。资本：期初余额 + 净利润 − 提款。流动负债：应付账款£22,000，工资应计£800。当资产总计等于权益加负债时，报表平衡。学员须正确分类资产并将透支冲抵流动资产。
8. Question 7 – Ratio Analysis: Profitability & Liquidity | 问题7 – 比率分析：盈利性与流动性
Using the above financial statements, key ratios are calculated. Gross profit margin = (Gross Profit / Revenue) × 100 = (£88,000 / £180,000) × 100 = 48.9%. Net profit margin = (£48,700 / £180,000) × 100 = 27.1%. Current ratio = Current Assets / Current Liabilities = (£15,000 + £76,000 + £1,200 + £300) / (£22,000 + £800 + £3,700*) = £92,500 / £26,500* = 3.49:1. (*Note: the overdraft may be treated as a current liability depending on exam instructions; here we include it for a conservative view). Acid test ratio = (Current Assets – Inventory) / Current Liabilities = (£92,500 – £15,000) / £26,500 = 2.92:1. These ratios indicate strong liquidity and profitability, but candidates should comment on benchmarks.
利用上述报表计算关键比率。毛利率 = (毛利 / 收入) × 100 = (£88,000 / £180,000) × 100 = 48.9%。净利率 = (£48,700 / £180,000) × 100 = 27.1%。流动比率 = 流动资产 / 流动负债 = (£15,000 + £76,000 + £1,200 + £300) / (£22,000 + £800 + £3,700*) = £92,500 / £26,500* = 3.49:1。（*注：银行透支可按考题要求视为流动负债，此处保守处理。）速动比率 = (流动资产 – 存货) / 流动负债 = (£92,500 – £15,000) / £26,500 = 2.92:1。这些比率表明流动性和盈利能力强劲，但考生应结合行业基准进行评价。
9. Question 8 – Correction of Errors and Suspense Account | 问题8 – 错误更正与暂记账户
A trial balance shows a difference of £450 debit, placed in a suspense account. Investigations reveal: (i) Sales of £500 were recorded as £550; (ii) Carriage inwards of £50 was debited to carriage outwards (both in expenses). Correction: (i) Sales overstated by £50 – Dr Sales £50, Cr Suspense £50. (ii) The £50 carriage inwards should not be in carriage outwards, but it is still an expense; however, the misclassification does not affect profit or trial balance totals. To clear the suspense, further errors must be found. In this scenario, assume a missed posting of £400 purchase returns – Dr Trade Payables £400, Cr Suspense £400. After all corrections, suspense is eliminated. The key principle: suspense is only a temporary account for unresolved differences.
试算平衡表出现借方差异£450，暂记账户存入差额。经查：(i) 销售收入£500被误记为£550；(ii) 购货运费£50被错误借记至销货运费（均属费用）。更正：(i) 销售多计£50——借 销售收入 £50，贷 暂记账户 £50。(ii) 该£50购货运费虽被错误归类，但仍为费用，不影响利润总额或试算平衡。要消除暂记，需查明其余错误。假设后来又发现一笔£400购货退回未过账——借 应付账款 £400，贷 暂记账户 £400。更正后暂记账户清零。核心原则：暂记账户只是未解决差异的临时存放科目。
10. Question 9 – Partnership Accounting Basics | 问题9 – 合伙会计基础
A and B share profits after allowing 5% interest on capital and splitting the remainder equally. Capital: A £100,000, B £80,000. Profit for the year is £40,000. Interest: A: £5,000, B: £4,000; total £9,000. Residual profit = £40,000 – £9,000 = £31,000, shared equally: £15,500 each. Total share: A £5,000 + £15,500 = £20,500; B £4,000 + £15,500 = £19,500. The appropriation account would show these allocations. A common exam error is forgetting to deduct interest before distributing the residual, or confusing the treatment of drawings (if interest on drawings was specified).
A和B合伙，约定按资本支付5%利息后，剩余利润平分。资本：A £100,000，B £80,000。本年利润£40,000。资本利息：A £5,000，B £4,000，合计£9,000。剩余利润=£40,000 – £9,000 = £31,000，平分各得£15,500。最终分配：A £5,000+£15,500=£20,500；B £4,000+£15,500=£19,500。利润分配账户将展示这些分配。常见考试错误：忘记在分配剩余前扣除利息，或混淆提款利息（若指定）的处理。
11. Question 10 – Concepts of Prudence and Accruals | 问题10 – 审慎性与应计概念
The prudence concept requires that assets and profits are not overstated and liabilities and expenses are not understated. For instance, creating an allowance for doubtful debts ensures trade receivables are stated at expected recoverable amount, not the full gross figure. The accruals (matching) concept dictates that income and expenses are recognised in the period to which they relate, not when cash is received or paid. For example, an electricity bill received after year-end for the previous period must be accrued. Together, these concepts ensure that financial statements faithfully represent the business’s performance and position.
审慎性概念要求不高估资产与利润，也不低估负债与费用。例如，计提呆账准备金确保应收账款按预计可收回额列示，而非全额总值。应计（配比）概念规定，收入和费用应在相关期间确认，而非现金收付时。例如，年末后收到的上一期间电费账单必须作为应计费用处理。这些概念共同确保财务报表如实反映企业的绩效与状况。
12. Final Tips for the AS OCR Accounting Exam | AS OCR 会计考试最后提示
Always show your workings, even for multiple-choice sections where appropriate, as OCR awards marks for correct method steps. Carefully read the requirement—whether to prepare a full statement or just an extract. Check the time allocation: if a calculation seems too long, you may be missing a short-cut. Before submitting, review adjustments for prepayments, accruals, and depreciation; these often differentiate grade boundaries. Finally, for written questions, use accurate accounting terminology and link to concepts, as examiners look for understanding beyond computation.
务必展示计算过程，即便在选择题部分，OCR也会对正确方法步骤给予分数。仔细审题，看清要求是编制完整报表还是仅需摘录。检查时间分配：若某计算看似耗时过长，可能意味着你错过了简便方法。交卷前重点复核预付、应计与折旧的调整，这类题目常划分不同等级。最后，在文字题中使用精确的会计术语并联系概念，考官看重的是超越计算的深层理解。
