1. Understanding the Exam Structure | 理解考试结构

The WJEC Year 12 Accounting unit test typically includes three sections: multiple-choice questions, short structured tasks, and one or two extended scenario-based questions. The assessment is designed to test both knowledge of accounting concepts and the application of bookkeeping techniques. You will be expected to complete ledger accounts, draft a trial balance, and prepare final accounts from given data.

WJEC 12 年级会计单元测试通常包含三个部分：选择题、简短的结构化任务以及一至两道基于场景的拓展题。该评估旨在同时考察会计概念的理解和簿记技巧的应用。你需要根据给定数据完成分类账户、编制试算平衡表并生成期末报表。

Familiarity with the command words is essential. Terms such as ‘State’, ‘Calculate’, ‘Prepare’, and ‘Explain’ require different levels of response. ‘Prepare’ means you must present a full financial statement in an acceptable format, while ‘Explain’ demands a written justification using accounting principles.

熟悉指令词至关重要。“State”（陈述）、“Calculate”（计算）、“Prepare”（编制）和“Explain”（解释）等术语要求的作答深度不同。“Prepare”意味着你必须按认可的格式编制完整财务报表，而“Explain”则要求使用会计原则进行书面解释。

Time management in the mock is a common challenge. Allocate roughly 1.5 minutes per mark. For a 60-mark paper, you have 90 minutes; leave 15 minutes for checking. Practise under timed conditions so you become comfortable moving from theory questions to numerical exercises.

模拟考试中的时间管理是一个常见挑战。大致按照每题 1.5 分钟分配时间。对于一份 60 分的试卷，你有 90 分钟；留出 15 分钟检查。在限时条件下练习，这样你在从理论题转向计算题时会更加自如。

2. Key Accounting Principles Tested | 考核的核心会计原则

Before tackling the numerical tasks, you need to identify which accounting concepts underpin the adjustments. The mock paper will embed fundamental principles such as the business entity concept, historical cost, going concern, accruals (matching), prudence, and consistency.

在着手处理计算题之前，你需要明确哪些会计概念是调整分录的基础。模拟卷会融入会计主体、历史成本、持续经营、权责发生制（配比）、谨慎性和一致性等基本原则。

Business entity concept — The owner’s personal transactions must be kept separate from the business records. 会计主体概念——业主的个人交易必须与企业的账簿完全分开。
Historical cost — Assets are recorded at their original purchase price, not at current market value. 历史成本——资产按其原始购置成本入账，而非当前市场价值。
Going concern — Financial statements are prepared assuming the business will continue operating for the foreseeable future. 持续经营——编制财务报表时假设企业将在可预见的未来持续经营。
Accruals (matching) — Expenses and revenues are recognised in the period they are incurred or earned, not when cash is paid or received. 权责发生制（配比）——费用和收入在实际发生或赚取的期间确认，而非在现金收付时。
Prudence — Profits are not anticipated, but all potential losses are provided for. 谨慎性——不预计利润，但对所有潜在损失计提准备。
Consistency — The same accounting treatment is applied from one period to the next to enable comparability. 一致性——同一会计处理方法连续使用，以便各期数据可比。

In the mock paper, you might be asked to justify why closing inventory is valued at the lower of cost and net realisable value. This directly tests prudence and matching. Be prepared to state the principle and link it to the adjustment.

在模拟卷中，你可能会被要求解释为何期末存货按成本与可变现净值孰低法计价。这直接考核谨慎性和配比原则。请准备好陈述原则并将其与调整分录联系起来。

3. Double-Entry Bookkeeping Questions | 复式记账题

A typical Section B task gives several raw transactions and asks you to enter them into the appropriate ledger accounts. The examiner is checking your ability to determine which accounts are debited and credited, and whether you understand the dual effect.

典型的 B 部分题目会给出若干原始交易，要求你将其过入恰当的分类账户。考官在考察你能否判断需借记和贷记哪些账户，以及你是否理解双重影响。

Sample transactions and entries (each transaction is shown in English followed by Chinese):

示例交易及分录（每笔交易先英文后中文）：

Transaction 1: Owner injects £15,000 cash into the business bank account. Debit Bank £15,000, Credit Capital £15,000. 交易1：业主将 15,000 英镑现金注入企业银行账户。借记银行账户 15,000 英镑，贷记资本账户 15,000 英镑。
Transaction 2: Purchased goods for resale on credit from Z Ltd, £3,000. Debit Purchases £3,000, Credit Trade Payables (Z Ltd) £3,000. 交易2：向 Z 公司赊购用于再出售的商品 3,000 英镑。借记采购账户 3,000 英镑，贷记应付贸易账款（Z 公司）3,000 英镑。
Transaction 3: Sold goods on credit to Customer A for £4,500. Debit Trade Receivables (A) £4,500, Credit Sales £4,500. 交易3：向客户 A 赊销商品 4,500 英镑。借记应收贸易账款（A）4,500 英镑，贷记销售收入 4,500 英镑。
Transaction 4: Paid rent by cheque, £800. Debit Rent expense £800, Credit Bank £800. 交易4：以支票支付租金 800 英镑。借记租金费用 800 英镑，贷记银行存款 800 英镑。
Transaction 5: Withdrew £500 cash from bank for office use. Debit Cash £500, Credit Bank £500. 交易5：从银行提取现金 500 英镑供办公室使用。借记现金 500 英镑，贷记银行存款 500 英镑。

Always reference the names of accounts exactly as they appear in the chart of accounts provided. For trade receivables and payables, ensure you use the individual customer or supplier name if the question requires subsidiary ledgers.

始终严格按照提供的会计科目表中所列账户名称进行记录。对于应收和应付贸易账款，如果题目要求使用明细账，请务必使用个别客户或供应商的名称。

Many students lose marks by omitting the date, narrative, or folio column in ledger accounts. In WJEC, neat presentation matters. Draw a three-column running balance format or T-accounts as instructed.

许多学生因在分类账户中遗漏日期、摘要或过账索引栏而丢分。在 WJEC 考试中，整洁的格式很重要。按题目要求画出三栏式序时余额格式或 T 型账户。

4. Trial Balance and Error Correction | 试算平衡表与错误更正

The trial balance section tests whether you can detect errors that do not affect the equality of debits and credits, as well as those that cause an imbalance. You may be asked to prepare a corrected trial balance after identifying errors from a given narrative.

试算平衡表部分考察你能否发现不影响借贷平衡的错误以及导致不平衡的错误。你可能会被要求在根据给定叙述找出错误后，编制更正后的试算平衡表。

Types of errors in a mock paper:

模拟卷中的错误类型：

Error (English)	错误（中文）	Correction (English)	更正（中文）
Commission error: £450 received from J. Lee was posted to J. Leach’s account.	账户记错错误：从 J. Lee 收到的 450 英镑被过入 J. Leach 的账户。	Debit J. Lee, credit J. Leach (to correct personal accounts).	借记 J. Lee，贷记 J. Leach（以更正个人账户）。
Error of principle: Purchase of computer equipment for £1,200 was debited to Purchases account.	原则性错误：购买计算机设备 1,200 英镑被借记到采购账户。	Debit Computer equipment, credit Purchases.	借记计算机设备，贷记采购账户。
Complete reversal: Payment of wages £900 was debited to Bank and credited to Wages.	完全颠倒：支付工资 900 英镑被借记银行、贷记工资费用。	Debit Wages £1,800, credit Bank £1,800 (double correction to reverse the original error and record the correct entry).	借记工资费用 1,800 英镑，贷记银行存款 1,800 英镑（双倍更正以冲销原错误并记录正确分录）。

When the trial balance totals do not agree, a suspense account is opened. You must show how the difference is eliminated after corrections. A typical task asks: ‘Open a suspense account and correct the following errors.’ Always recalculate the trial balance after adjustments to confirm it now balances.

当试算平衡表合计数不一致时，需开设暂记账户。你必须展示更正后差额是如何消除的。典型题目要求：“开设暂记账户并更正下列错误。”调整后务必重新计算试算平衡表，以确认其现在平衡。

5. Income Statement Preparation | 利润表编制

The income statement question normally provides a trial balance together with adjustments for closing inventory, accruals, prepayments, and depreciation. You are required to prepare the income statement for the year ended.

利润表题目通常给出试算平衡表以及期末存货、应计费用、预付费用和折旧等调整项。你需要编制截至某日的年度利润表。

Sample adjustment walkthrough:

调整步骤示例：

English: The trial balance shows Rent £12,000 debit. At the year-end, £3,000 rent has been prepaid. This means the expense for the year should be £9,000. Subtract the prepayment from the trial balance figure in the income statement, and show the £3,000 prepayment as a current asset in the balance sheet.

中文：试算平衡表显示租金费用借方 12,000 英镑。在年末，有 3,000 英镑租金是预付的。这意味着本年费用应为 9,000 英镑。在利润表中从试算平衡表数额中减掉预付部分，并将 3,000 英镑预付租金作为资产负债表中的流动资产列示。

English: Closing inventory is valued at £5,600 at the lower of cost and net realisable value. In the income statement, you must deduct closing inventory from the cost of sales: Cost of sales = Opening inventory + Purchases – (Purchase returns) + Carriage inwards – Closing inventory.

中文：期末存货按成本与可变现净值孰低法计价为 5,600 英镑。在利润表中，你必须从销售成本中减去期末存货：销售成本 = 期初存货 + 采购 -（采购退回）+ 购货运费 – 期末存货。

Gross Profit = Sales − Sales Returns − Cost of Sales / 毛利 = 销售收入 − 销售退回 − 销售成本

Many candidates forget to include carriage inwards in the cost of sales. It is treated as part of the cost of purchasing goods. Carriage outwards, however, is a selling expense listed below gross profit. Always check the nature of each carriage.

很多考生忘记将购货运费计入销售成本。它被视为采购货物成本的一部分。而销货运费则是毛利下列示的一项销售费用。务必区分两种运费的性质。

Ensure the final income statement shows clear headings: name of business, title ‘Income Statement for the year ended [date]’. Present gross profit and net profit prominently. Format marks can be earned easily.

确保最终利润表标题清晰：企业名称、标题“截至[日期]的利润表”。毛利和净利润要突出列示。格式分很容易拿到。

6. Balance Sheet and Adjustments | 资产负债表与调整

After the income statement, you are typically asked to prepare a balance sheet (statement of financial position) incorporating the year-end adjustments. The balance sheet must be classified into non-current and current assets, capital, and non-current and current liabilities.

在利润表之后，通常要求你编制反映年末调整的资产负债表（财务状况表）。资产负债表必须分类为非流动资产、流动资产、资本、非流动负债和流动负债。

Key adjustments to capture in the balance sheet:

资产负债表中需体现的关键调整：

Show the net book value (NBV) of non-current assets: Cost − Accumulated depreciation. 列示非流动资产的账面净值：成本 − 累计折旧。
Include closing inventory under current assets. 将期末存货列入流动资产。
Separately show prepayments (e.g., Prepaid rent) and accruals (e.g., Accrued electricity) as current assets and current liabilities respectively. 分别将预付项目（如预付租金）和应计项目（如应计电费）列为流动资产和流动负债。
Ensure the bank balance matches the corrected cash book after any reconciliation. 确保银行存款余额与经调节后的现金账簿余额相符。
Transfer the net profit from the income statement to the capital section, and deduct drawings. 将净利润从利润表转入资本部分，并减去业主提款。

In a WJEC mock, you might see a note: ‘Inventory at 31 December is valued at £8,200. A provision for doubtful debts is to be created at 5% of trade receivables.’ You would calculate the provision, offset it against trade receivables in the balance sheet, and also charge the increase in provision as an expense in the income statement.

在 WJEC 模拟卷中，你可能会看到这样的注释：“12 月 31 日存货价值 8,200 英镑。应按应收贸易账款余额的 5% 计提坏账准备。”你需要计算准备金额，在资产负债表中将其与应收贸易账款相抵，并在利润表中将准备增加额确认为费用。

Always verify the accounting equation: Total assets = Capital + Total liabilities. If it balances, you have likely handled adjustments correctly.

始终验证会计等式：总资产 = 资本 + 总负债。如果等式平衡，说明你可能正确处理了各项调整。

7. Depreciation and Provisions | 折旧与准备

Depreciation is tested regularly. You must know both the straight-line method and the reducing (diminishing) balance method. The straight-line method charges an equal amount each year: (Cost − Residual value) ÷ Useful life. The reducing balance method applies a fixed percentage to the carrying amount.

折旧经常被考核。你必须掌握直线法和余额递减法。直线法每年计提等额折旧： (成本 − 残值) ÷ 使用年限。余额递减法则对账面净值按固定百分比计提折旧。

Straight-line annual depreciation = (Cost − Residual value) ÷ Useful life (years)
直线法年折旧额 = (成本 − 残值) ÷ 使用年限（年）

Reducing balance depreciation = Carrying amount × Depreciation rate (%)
余额递减法折旧 = 账面净值 × 折旧率（%）

In your mock, you may be given a part-exchange disposal of a non-current asset. The steps: remove the asset’s cost from the account, remove the accumulated depreciation to date, record the part-exchange allowance as proceeds, and post the profit or loss on disposal to the income statement.

在模拟卷中，你可能会遇到以旧换新处置非流动资产的题目。步骤如下：从账户中移除资产成本，移除截至处置日的累计折旧，记录以旧换新折抵额作为处置收入，并将处置损益过入利润表。

Provision for doubtful debts: An increase in provision is an expense in the income statement and is deducted from trade receivables on the balance sheet. A decrease is credited to the income statement. Remember the prudence concept – do not overstate assets.

坏账准备：准备增加额是利润表中的一项费用，并在资产负债表上从应收贸易账款中扣除。准备减少额则贷记利润表。记住谨慎性概念——不要高估资产。

Present depreciation calculations clearly in a separate working note. This earns method marks even if the final figure is wrong. Label your workings as ‘Workings for depreciation charge for the year ended…’

在单独的工作底稿中清晰展示折旧计算过程。这样即使最终数字错误，也能获得方法分。将计算过程标注为“截至…年度的折旧费用计算工作底稿”。

8. Control Accounts and Reconciliations | 控制账户与调节

Sales ledger control account and purchases ledger control account questions are common. These accounts summarise the total receivables and payables from the subsidiary ledgers. You may have to start with a given balance and adjust for credit sales, receipts from customers, discounts allowed, returns inwards, and bad debts written off.

销售总账控制账户和采购总账控制账户的题目很常见。这些账户汇总了来自明细分类账的应收和应付账款总额。你可能需要从给定余额开始，并根据赊销额、客户回款、给予的折扣、销售退回以及坏账注销进行调整。

Item (English)	项目（中文）	Sales Ledger Control Account effect (English)	销售总账控制账户影响（中文）
Credit sales	赊销额	Debit side (increase)	借记（增加）
Receipts from trade receivables	来自应收贸易账款的收款	Credit side (decrease)	贷记（减少）
Discounts allowed	给予的折扣	Credit side	贷记
Bad debts written off	坏账注销	Credit side	贷记

Bank reconciliation: You compare the cash book (bank columns) with the bank statement. Items in the cash book but not on the statement (unpresented cheques, deposits in transit) and vice versa (bank charges, direct debits, credit transfers) must be reconciled. The adjusted cash book balance should equal the adjusted bank statement balance.

银行余额调节表：你将现金账簿（银行栏目）与银行对账单进行比较。现金账簿已记录但对账单未显示的项目（未兑付支票、在途存款），以及对账单已显示但现金账簿未记录的项目（银行手续费、直接借记、贷项转账），都必须进行调节。调整后的现金账簿余额应等于调整后的银行对账单余额。

In the mock, you might be asked to update the cash book first, then prepare the bank reconciliation statement. Always start by entering the missing items into the cash book, calculate the revised balance, and then reconcile to the bank statement.

在模拟卷中，你可能会被要求先更新现金账簿，然后编制银行余额调节表。一定要先将缺失项目计入现金账簿，计算出修正后的余额，然后再与银行对账单进行调节。

9. Interpretation of Financial Information | 财务信息的解读

The final section often assesses your ability to calculate and comment on accounting ratios. The WJEC specification includes profitability ratios (gross profit margin, net profit margin, return on capital employed) and liquidity ratios (current ratio, quick ratio / acid test).

最后一部分常常考核你计算和评述会计比率的能力。WJEC 考纲包括盈利能力比率（毛利率、净利率、运用资本报酬率）和流动性比率（流动比率、速动比率/酸性测试比率）。

Gross Profit Margin = (Gross Profit ÷ Sales Revenue) × 100
毛利率 = (毛利 ÷ 销售收入) × 100

Current Ratio = Current Assets ÷ Current Liabilities
流动比率 = 流动资产 ÷ 流动负债

When commenting, don’t just state the change in percentage points; link it to possible business causes. For example, a fall in gross margin could be due to increased purchase costs without a corresponding rise in selling price, or inventory theft. A declining quick ratio may signal poor cash management.

在评述时，不要仅仅陈述百分点的变化；要将其与可能的业务原因联系起来。例如，毛利率下降可能是由于进货成本上升而售价未相应提高，或者存货被盗。速动比率下降则可能表明现金管理不佳。

Practice writing short evaluative sentences: ‘The net profit margin has improved from 12% to 15%, suggesting better control of operating expenses. However, the current ratio has fallen below 1.2:1, which could concern short-term creditors.’

练习撰写简短的评述性语句：“净利润率从 12% 提高到 15%，表明企业更好地控制了营业费用。然而，流动比率已降至 1.2:1 以下，这可能引起短期债权人的担忧。”

If a mock question provides comparative figures, you can calculate the ratios for both years and discuss trends. Always show full workings; a correct formula and substitution earn marks even if the final answer has a small rounding difference.

如果模拟题提供了比较数据，你可以计算两年度的比率并讨论其变化趋势。始终展示完整的计算过程；即使最终答案存在微小的四舍五入差异，正确的公式和代入数据都能得分。

10. Mock Exam Tips and Common Mistakes | 模拟考试技巧与常见错误

Avoiding frequent pitfalls can significantly boost your score. One of the most common mistakes is confusing profit mark-up with profit margin. Mark-up is profit expressed as a percentage of cost of sales, while margin is profit as a percentage of selling price. The examiner often uses this to test the cost of missing inventory.

避免常见错误可以显著提高你的分数。最常见的错误之一是混淆加成率与利润率。加成率是利润占销售成本的百分比，而利润率是利润占售价的百分比。考官常常利用这一点来测试失踪存货的成本。

Another error is misclassifying expenses. Always check whether an item is a selling and distribution cost or an administrative expense. For instance, carriage outwards is a selling expense, while office salaries are administrative. Correct classification ensures accurate ratio analysis.

另一个错误是费用分类错误。一定要确认某个项目属于销售与配送费用还是行政费用。例如，销货运费是销售费用，而办公室薪金是行政费用。正确的分类能确保比率分析的准确性。

Many candidates lose time by writing lengthy narratives where only figures are required. Read the instructions carefully; if the question asks ‘Prepare’, focus on the numbers in the proper format. Only write explanations when the command word is ‘Explain’ or ‘Advise’.

许多考生在只需列出数字的地方却写了冗长的文字说明，从而浪费了时间。仔细阅读答题指令；如果题目要求“编制”（Prepare），就专注于用恰当格式呈现数字。只有当指令词是“解释”（Explain）或“建议”（Advise）时才写解释。

Finally, always cross-check the balance sheet with the adjusted trial balance or previous statements. If the net assets at the end of the year do not equal the opening capital plus net profit less drawings, there is an error. Use this built-in check to catch mistakes.

最后，务必将资产负债表与调整后的试算平衡表或之前编制的报表进行交叉核对。如果年末净资产不等于期初资本加净利润减去提款，则存在错误。利用这种内置验证来发现错误。
