1. Overview of the Mock Paper | 模拟试卷概览
The mock paper is structured to mirror the WJEC Unit 1 assessment, combining multiple-choice questions, short structured questions, and one extended scenario-based task. It tests foundational accounting knowledge under timed conditions, with a total of 80 marks available over 90 minutes.
模拟试卷仿照 WJEC 第一单元测评结构，包含选择题、简答题以及一道基于情境的拓展题。它在限时条件下考查基础会计知识，总分 80 分，考试时长 90 分钟。
Topics include recording transactions in ledger accounts, preparing a trial balance, adjusting for accruals and prepayments, drafting financial statements, calculating depreciation, and applying accounting concepts. The exam also requires you to identify and correct errors using journal entries and a suspense account.
考查主题包括在分类账中记录交易、编制试算平衡表、处理应计与预付款项调整、起草财务报表、计算折旧以及运用会计概念。考试还要求你通过日记账分录和暂记账户识别并更正差错。
2. Question 1: Double-Entry Bookkeeping | 问题 1：复式记账法
Question 1 presents a series of transactions for a sole trader and asks you to complete the relevant ledger accounts. You must correctly identify the debit and credit entries, apply the duality concept, and balance off the accounts at the end of the period.
问题 1 列出某个体经营者的若干交易，要求你完成相关分类账账户。你必须正确区分借方和贷方分录，运用复式记账原则，并在期末对账户进行结平。
A typical transaction involves purchasing inventory on credit: debit Purchases, credit Trade Payables. For a cash sale, debit Cash, credit Sales. Always check that the total debits equal total credits for every transaction before moving on.
典型交易如赊购存货：借记采购，贷记应付账款。对于现金销售，借记现金，贷记销售收入。务必在继续下一笔之前检查每笔交易的借方总额等于贷方总额。
- English: Debit the receiving account, credit the giving account.
- 中文：借记接收账户，贷记付出账户。
- English: For expenses, debit the expense account; for income, credit the income account.
- 中文：费用发生时借记费用账户；收入实现时贷记收入账户。
3. Question 2: Trial Balance Adjustments | 问题 2：试算平衡调整
The trial balance extract includes year-end adjustments such as accrued rent, prepaid insurance, and depreciation. You need to show how these adjustments affect the trial balance or prepare an extended trial balance with adjusted columns.
试算平衡表摘录包含期末调整项，如应付租金、预付保险费和折旧。你需要展示这些调整如何影响试算平衡表，或编制带有调整栏的扩展试算平衡表。
An accrual increases an expense in the income statement and creates a current liability. For example, unpaid wages of £500 require a debit to Wages £500 and a credit to Accruals (Wages Payable) £500. A prepayment reduces the expense: if Insurance was prepaid by £200, the prepayment is deducted from the trial balance figure before it enters the income statement.
应计费用增加利润表中的费用并产生流动负债。例如，未付工资 £500 需借记工资 £500，贷记应计负债（应付工资）£500。预付款项则减少费用：如果保险费预付 £200，预付额从试算平衡表数字中扣除后再计入利润表。
| Adjustment Type | 调整类型 | Income Statement Effect | 利润表影响 | Statement of Financial Position Effect | 财务状况表影响 |
|---|---|---|---|---|---|
| Accrual | 应计 | Increase expense | 增加费用 | Add to current liabilities | 加至流动负债 |
| Prepayment | 预付 | Decrease expense | 减少费用 | Add to current assets | 加至流动资产 |
4. Question 3: Income Statement Preparation | 问题 3：利润表编制
Using an adjusted trial balance, you must prepare an income statement for the year ended. This includes calculating gross profit, adding other income, deducting operating expenses, and arriving at net profit.
你需要根据调整后的试算平衡表编制年度利润表。包括计算毛利、加上其他收益、扣减营业费用，最终得出净利润。
Start with Revenue less Cost of Sales. Cost of Sales is calculated as Opening Inventory + Purchases – Closing Inventory. Then list expenses such as rent, wages, utilities, and depreciation. Remember to use the adjusted figures after accruals and prepayments.
首先从销售收入中减去销售成本。销售成本计算公式为：期初存货 + 采购 – 期末存货。然后列出各类费用，如租金、工资、水电费和折旧。务必使用经过应计和预付调整后的数字。
Gross Profit = Revenue – Cost of Sales 毛利 = 销售收入 – 销售成本
Cost of Sales = Opening Inventory + Purchases – Closing Inventory 销售成本 = 期初存货 + 采购 – 期末存货
A common mistake is omitting carriage inwards from the cost of sales calculation. Carriage inwards is added to purchases, while carriage outwards is treated as a selling expense in the income statement.
常见错误是在销售成本计算中遗漏了购货运费。购货运费应加至采购成本，而销货运费则在利润表中列为销售费用。
5. Question 4: Statement of Financial Position | 问题 4：财务状况表
The statement of financial position (balance sheet) must be prepared in accordance with the accounting equation, classifying items as non-current assets, current assets, current liabilities, non-current liabilities, and equity.
财务状况表（资产负债表）必须按照会计等式编制，将项目分为非流动资产、流动资产、流动负债、非流动负债和所有者权益。
Start with non-current assets at carrying amount (cost less accumulated depreciation). Then current assets (inventory, trade receivables, prepayments, cash). Deduct current liabilities (trade payables, accruals, bank overdraft) to show net current assets. Then deduct non-current liabilities, and finally add capital and retained profit to complete the equity section.
首先列示非流动资产的账面净值（成本减累计折旧）。然后是流动资产（存货、应收账款、预付款、现金）。扣除流动负债（应付账款、应计负债、银行透支）得到流动资产净额。再减去非流动负债，最后加上资本和留存利润以完成权益部分。
Always ensure that total assets equal total equity plus liabilities. If the statement does not balance, double-check the net profit figure transferred from the income statement and adjustments for drawings.
务必确保总资产等于总权益加负债。如果报表不平，需复核从利润表转入的净利润数据以及提款调整。
6. Question 5: Accounting Concepts | 问题 5：会计概念
This section tests your understanding of fundamental accounting concepts such as going concern, accruals (matching), consistency, prudence, and business entity. You may be asked to define them and apply them to a given scenario.
本节测试你对基本会计概念的理解，如持续经营、应计制（配比）、一致性、谨慎性和企业主体。你可能需要给出定义并应用于给定情境。
The going concern concept assumes the business will continue operating for the foreseeable future, justifying the valuation of assets at cost rather than forced-sale value. The accruals concept requires transactions to be recorded in the period they occur, not when cash is received or paid.
持续经营概念假定企业在可预见的未来继续运作，从而可以按成本而非强制出售价值评估资产。应计制概念要求交易在发生当期记录，而非在收到或支付现金时记录。
- English: Prudence dictates that losses should be anticipated but profits only recognised when realised.
- 中文：谨慎性原则要求预计损失，而利润仅在实现时确认。
- English: Consistency means applying the same accounting methods from period to period to allow meaningful comparison.
- 中文：一致性意味着在不同期间采用相同的会计方法，以便进行有意义的比较。
7. Question 6: Depreciation Methods | 问题 6：折旧方法
The question requires calculating annual depreciation using both the straight-line method and the reducing (diminishing) balance method. You must also show the impact on the income statement and the carrying amount on the statement of financial position.
题目要求分别用直线法和余额递减法计算年折旧额，并展示对利润表的影响及财务状况表中的账面净值。
For straight-line depreciation, the formula is:
对于直线法折旧，公式为：
Annual Depreciation = (Cost – Residual Value) ÷ Useful Life 年折旧额 = (成本 – 残值) ÷ 使用年限
For the reducing balance method, a fixed percentage is applied to the net book value (cost less accumulated depreciation). The exam may provide the percentage, e.g. 20% p.a. reducing balance. Be careful to calculate the second year’s depreciation on the reduced net book value.
余额递减法则是对账面净值（成本减累计折旧）应用固定百分比。考试可能提供该百分比，例如每年 20% 余额递减法。注意第二年折旧需按减少后的账面净值计算。
| Year | 年份 | Depreciation Charge (Straight-Line) | 折旧费用（直线法） | Carrying Amount | 账面净值 |
|---|---|---|---|---|---|
| 1 | 第 1 年 | £1,000 | £1,000 | £4,000 | £4,000 |
| 2 | 第 2 年 | £1,000 | £1,000 | £3,000 | £3,000 |
8. Question 7: Ratio Analysis | 问题 7：比率分析
You are given extracts from the financial statements and asked to calculate and interpret profitability and liquidity ratios. Typical ratios include gross profit margin, net profit margin, and current ratio.
题目提供财务报表摘录，要求计算并解读盈利能力和流动性比率。典型比率包括毛利率、净利率和流动比率。
Ratio formulas must be memorised. Gross profit margin is (Gross Profit ÷ Revenue) × 100. It indicates how efficiently the business controls its cost of sales. A decline may suggest increased purchase costs or markdowns.
比率公式必须熟记。毛利率 = (毛利 ÷ 销售收入) × 100。它反映企业管理销售成本的效率。比率下降可能暗示采购成本上升或降价销售。
Net Profit Margin = (Net Profit ÷ Revenue) × 100 净利率 = (净利润 ÷ 销售收入) × 100
Current Ratio = Current Assets ÷ Current Liabilities 流动比率 = 流动资产 ÷ 流动负债
Interpretation is crucial. A current ratio of 1.5:1 suggests adequate short-term liquidity, but if trade receivables are slow to collect, cash may still be tight. Always link ratio analysis to the business context.
解读至关重要。流动比率 1.5:1 表明短期流动性充足，但如果应收账款回款慢，现金仍可能紧张。分析比率时务必结合企业实际背景。
9. Question 8: Errors and Suspense Accounts | 问题 8：差错与暂记账户
This question requires you to identify types of errors that affect or do not affect the trial balance agreement. You must correct the errors using journal entries and, where necessary, clear the suspense account.
此题要求识别会影响或不影响试算平衡的差错类型。你必须使用日记账分录更正错误，并在必要时结清暂记账户。
Errors that do not affect the trial balance include omission, commission, principle, original entry, and compensating errors. These require correcting journal entries. Errors that do affect the trial balance — such as a single entry or a transposition error — will produce a difference posted to a suspense account.
不影响试算平衡的差错包括遗漏、账户记错、原则性错误、原始分录错误和抵消性错误。这些需要更正日记账。影响试算平衡的差错——如单边分录或数字换位错误——会产生差额，记入暂记账户。
To clear the suspense account, first correct the original error by debiting/crediting the correct account and crediting/debiting suspense. Once all errors are corrected, the suspense account balance should be zero.
要结清暂记账户，首先更正原错误，借记/贷记正确账户并贷记/借记暂记账户。所有错误更正后，暂记账户余额应为零。
10. Common Mistakes to Avoid | 常见错误防范
Many students lose marks by misclassifying expenses or failing to apply year-end adjustments consistently. Double-check that carriage inwards is added to purchases, not treated as a separate expense.
许多学生因错误分类费用或未能一致运用期末调整而失分。务必复查购货运费是否加至采购，而非当作单独费用处理。
Another frequent error is producing a statement of financial position that does not balance. This usually occurs because the net profit is incorrectly calculated or drawings are deducted from capital in the wrong section. Always re-calculate the closing capital.
另一个常见错误是财务状况表无法平衡。这通常是由于净利润计算有误，或提款被错误地从资本中扣除。务必重新计算期末资本。
Closing capital = Opening Capital + Net Profit – Drawings. If this figure does not match the total equity on your statement, review the income statement and any additional capital introduced.
期末资本 = 期初资本 + 净利润 – 提款。如果该数字与报表上的总权益不符，请复核利润表以及是否有追加资本投入。
11. Key Revision Tips | 关键复习提示
Practice past papers under timed conditions to improve speed and accuracy. Focus on the ‘why’ behind each adjustment — understanding the accruals concept is more valuable than memorising journal entries alone.
在限时条件下练习历年真题，提高速度和准确性。关注每项调整背后的“原因”——理解应计制概念比单纯记忆日记账分录更有价值。
Create summary sheets for formulas and concept definitions. Use mnemonics to recall the order of the income statement and statement of financial position. Regularly test yourself on double-entry rules by writing out journal entries for sample transactions.
为公式和概念定义制作摘要表。运用记忆术回想利润表和财务状况表的编制顺序。通过为样题交易写出日记账分录，定期自测复式记账规则。
Finally, allocate your exam time wisely. Spend approximately 1 minute per mark on calculation questions, and leave 10 minutes at the end to check arithmetic and financial statement balancing.
最后，合理分配考试时间。计算题每分值约花 1 分钟，并留出最后 10 分钟检查计算准确性和财务报表的平衡关系。
