📚 Year 11 AQA Accounting: Unit Test Mock Analysis | Year 11 AQA 会计：单元测试模拟卷解析
Unit tests are a crucial checkpoint for Year 11 Accounting students. They bring together all the fundamental concepts, from double-entry to financial statements, and reveal exactly where strengths and weaknesses lie. This walkthrough of a typical AQA-style mock paper will not only explain the correct answers but also help you understand the reasoning behind each entry, adjustment and calculation.
单元测试是 Year 11 会计学生的重要检验节点。它把复式记账、财务报表等所有基础概念整合在一起，精准暴露强项和弱项。这份针对典型 AQA 风格模拟卷的解析不仅会给出正确答案，还会帮助你理解每一笔分录、调整和计算背后的逻辑。
1. Overview of the Unit Test | 单元测试概览
A standard Year 11 mock paper is usually divided into four sections. Section A contains 20 multiple-choice questions testing definitions, the accounting equation and basic classifications. Section B asks for short double-entry journal entries. Section C provides a trial balance with adjustments such as accruals, prepayments and depreciation. Section D requires the preparation of an income statement and a statement of financial position. The total mark is often 100, and time allowed is 90 minutes.
一份标准的 Year 11 模拟卷通常划分为四个部分。A 部分是 20 道选择题，考查定义、会计等式和基本分类。B 部分要求写出简短的复式记账分录。C 部分给出试算表以及应计、预付和折旧等调整。D 部分要求编制损益表和资产负债表。总分通常为 100 分，考试时间 90 分钟。
Understanding the weight of each section helps you allocate revision time wisely. Section A can be practised quickly, while Sections C and D demand deeper understanding of adjusting entries and financial statement structure.
了解各部分的权重有助于合理分配复习时间。A 部分可以快速练习，而 C 和 D 部分则要求对调整分录和财务报表结构有更深入的理解。
2. Section A Spotlight: The Accounting Equation | 选择题聚焦：会计等式
One common multiple-choice question tests whether you can predict the impact of a transaction on the accounting equation. Consider this example:
常见的一道选择题考查你是否能预测某笔交易对会计等式的影响。看这个例子：
"Which of the following transactions will increase total assets?"
A. Purchasing inventory on credit
B. Repaying a bank loan
C. The owner introduces additional capital in cash
D. Paying a trade payable
「以下哪项交易会增加资产总额？」
A. 赊购存货
B. 偿还银行贷款
C. 所有者投入额外现金资本
D. 支付应付账款
The correct answer is C. When the owner puts cash into the business, we debit Bank (asset up) and credit Capital (equity up). Total assets rise. In option A, inventory (asset) and trade payables (liability) both increase, so total assets are unchanged. In B, bank (asset) falls and the loan (liability) falls, keeping total assets unchanged. In D, bank decreases and trade payables decrease; again, no overall change in total assets.
正确答案是 C。当所有者把现金投入企业时，我们借记银行存款（资产增加）并贷记资本（权益增加）。资产总额上升。选项 A 中存货（资产）和应付账款（负债）同时增加，资产总额不变。选项 B 中银行存款（资产）减少而贷款（负债）减少，总额不变。选项 D 中银行存款减少而应付账款减少，资产总额仍不变。
3. Double-Entry: Recording Transactions | 复式记账：记录交易
In Section B you might be asked to journalise a straightforward transaction. For example: "On 5 April, the business bought office equipment costing £2,000, paying by cheque."
在 B 部分你可能需要为一笔直接交易编制分录。例如：「4 月 5 日，企业购买办公设备，成本 2,000 英镑，以支票支付。」
The correct journal is:
Debit Office Equipment £2,000
Credit Bank £2,000
正确的分录为：
借记 办公设备 2,000 英镑
贷记 银行存款 2,000 英镑
Always remember: debit the asset that comes in, credit the asset that goes out. Office equipment is a non-current asset, so it increases on the debit side. Bank is also an asset; when it decreases, we credit it.
请始终牢记：借记进入的资产，贷记离开的资产。办公设备是非流动资产，因此在借方增加。银行存款也是资产，当它减少时我们记在贷方。
A second common task is recording a cash sale. "Sold goods for cash £500 (cost of goods sold £300)." The double-entry involves two parts: Debit Cash £500, Credit Sales £500 and Debit Cost of Sales £300, Credit Inventory £300. This illustrates how the income statement accounts are updated at the same time.
另一个常见任务是记录现销。「以现金销售商品 500 英镑（销售成本 300 英镑）。」此复式分录包含两部分：借记现金 500 英镑，贷记销售收入 500 英镑，同时借记销售成本 300 英镑，贷记存货 300 英镑。这展示了损益表账户是如何同时更新的。
4. Constructing a Trial Balance | 编制试算表
In Section C, you are often given a list of ledger balances and asked to spot why the trial balance does not balance. Imagine the debit column totals £56,700 and the credit column totals £57,200. The difference is £500, and the credit side is larger.
在 C 部分中，通常会给你一份分类账余额列表，要求找出试算表不平衡的原因。假设借方栏合计数为 56,700 英镑，贷方栏合计数为 57,200 英镑。差额为 500 英镑且贷方较大。
A common error could be that a debit balance of £500 on the 'stationery' account has been incorrectly listed on the credit side, or a credit balance of £250 has been added twice. By checking each balance against the ledger, the mistake can be identified. Always calculate the difference, halve it if you suspect a transposition error, and search for a missing or duplicated entry.
常见的错误可能是「文具费」账户的 500 英镑借方余额被错误地列入贷方栏，或者一笔 250 英镑的贷方余额被加了两次。通过逐一核对分类账余额就能找出错误。请务必计算差额，如果你怀疑有换位错误可将差额除以二，并查找遗漏或重复的分录。
5. Accruals and Prepayments Adjustments | 应计与预付调整
Mock papers love testing whether you can adjust for accruals and prepayments. A typical question: "On 1 January the business paid an annual insurance premium of £1,200. The financial year ends on 31 March. Calculate the prepayment and the insurance expense for the year."
模拟卷热衷于考查你是否会对应计和预付进行调整。典型题目：「1 月 1 日企业支付了年度保险费 1,200 英镑。会计年度截止于 3 月 31 日。计算预付额和当年保险费。」
The insurance covers 12 months. By 31 March, only 3 months (January–March) have been used. Therefore, the expense for the year is 3/12 × £1,200 = £300. The remaining 9 months (£00) relate to the next financial year and must be shown as a prepayment (a current asset).
保险覆盖 12 个月。到 3 月 31 日，只使用了 3 个月（1 月至 3 月）。因此，当年费用为 3/12 × 1,200 英镑 = 300 英镑。剩下的 9 个月（900 英镑）属于下一个会计年度，必须列示为预付费用（一项流动资产）。
If the initial payment was debited entirely to insurance expense, the adjusting entry is:
Debit Prepayments £900
Credit Insurance Expense £900
如果初始付款时全部借记了保险费用，则调整分录为：
借记 预付费用 900 英镑
贷记 保险费用 900 英镑
6. Depreciation Calculation | 折旧计算
Depreciation is another core adjustment. A machine was bought for £10,000, with an estimated residual value of £1,000 and a useful life of 5 years. Using the straight-line method, the annual depreciation charge is:
折旧是另一项核心调整。一台机器以 10,000 英镑购入，预计残值 1,000 英镑，使用年限 5 年。采用直线法，年度折旧费用为：
Annual Depreciation = (Cost – Residual Value) ÷ Useful Life
年折旧额 = (成本 – 残值) ÷ 使用年限
= (£10,000 – £1,000) ÷ 5 = £1,800
The double-entry to record this is:
Debit Depreciation Expense £1,800
Credit Accumulated Depreciation £1,800
记录此折旧的分录为：
借记 折旧费用 1,800 英镑
贷记 累计折旧 1,800 英镑
In the statement of financial position, the machine is shown at its carrying amount: Cost £10,000 less accumulated depreciation £1,800 = £200. This approach matches the cost of the asset to the periods that benefit from its use.
在资产负债表中，该机器以其账面金额列示：成本 10,000 英镑减去累计折旧 1,800 英镑 = 8,200 英镑。这一方法将资产的成本与其使用期间相匹配。
7. Bad Debts and Provision for Doubtful Debts | 坏账与可疑债务准备
A mock question often combines specific bad debts with a general provision. At year-end, trade receivables total £50,000. A customer owing £2,000 is declared bankrupt, and the business maintains a general provision of 2% on the remaining receivables. The opening provision balance is £500.
模拟题经常把特定坏账与一般准备结合起来。年末应收账款总额为 50,000 英镑。一名欠款 2,000 英镑的客户宣告破产；企业按剩余应收账款的 2% 计提一般准备。期初准备余额为 500 英镑。
Step 1: Write off the specific bad debt.
Debit Bad Debts £2,000, Credit Trade Receivables £2,000.
Step 2: Calculate the required provision. After write-off, receivables = £48,000. Provision needed = 2% × £48,000 = £960.
Step 3: Compare with the opening provision. Increase needed = £960 – £500 = £460.
Debit Provision Expense (Income Statement) £460, Credit Provision for Doubtful Debts £460.
第 1 步：核销特定坏账。
借记 坏账费用 2,000 英镑，贷记 应收账款 2,000 英镑。
第 2 步：计算所需准备。核销后应收账款为 48,000 英镑。所需准备 = 2% × 48,000 英镑 = 960 英镑。
第 3 步：与期初准备比较。需增加额 = 960 英镑 – 500 英镑 = 460 英镑。
借记 准备费用（损益表）460 英镑，贷记 可疑债务准备 460 英镑。
The total charge in the income statement consists of the specific bad debt (£2,000) plus the increase in provision (£460), giving £2,460.
损益表中的费用总额包括特定坏账（2,000 英镑）加上准备增加额（460 英镑），共计 2,460 英镑。
8. Preparing an Income Statement | 编制损益表
Section D will present you with an adjusted trial balance. A condensed extract might show:
| Sales | £120,000 |
| Sales returns (Returns inwards) | £2,000 |
| Opening inventory | £18,000 |
| Purchases | £80,000 |
| Carriage inwards | £1,500 |
| Closing inventory | £22,000 |
Net sales = Sales – Returns inwards = £120,000 – £2,000 = £118,000.
净销售额 = 销售收入 – 销售退回 = 120,000 英镑 – 2,000 英镑 = 118,000 英镑。
Cost of sales = Opening inventory + Purchases + Carriage inwards – Closing inventory = £18,000 + £80,000 + £1,500 – £22,000 = £77,500.
销售成本 = 期初存货 + 购货 + 购货运费 – 期末存货 = 18,000 英镑 + 80,000 英镑 + 1,500 英镑 – 22,000 英镑 = 77,500 英镑。
Gross profit = £118,000 – £77,500 = £40,500. Additional overheads such as discount allowed (£500) and depreciation (£1,800) are deducted later to arrive at net profit.
毛利 = 118,000 英镑 – 77,500 英镑 = 40,500 英镑。其他间接费用如折扣允许（500 英镑）和折旧（1,800 英镑）需在后面扣除以得出净利润。
9. Statement of Financial Position Highlights | 资产负债表重点
Using adjustments from preceding sections, a simplified statement of financial position at 31 March would include:
| Non-current assets | |
|---|---|
| Office equipment at cost | £30,000 |
| Less Accumulated depreciation | (£5,000) |
| Carrying amount | £25,000 |
| Current assets | |
| Inventory | £22,000 |
| Trade receivables (£48,000 net of provision) | £47,040 |
| Prepayment | £900 |
| Bank | £5,000 |
| Total current assets | £75,940 |
| Current liabilities | |
| Trade payables | £15,000 |
| Accrued expenses | £200 |
| Total current liabilities | £15,200 |
Net current assets (working capital) = £75,940 – £15,200 = £60,740. Total net assets = £25,000 + £60,740 = £ to the closing capital, which includes the opening capital plus net profit less drawings.
净流动资产（营运资金）= 75,940 英镑 – 15,200 英镑 = 60,740 英镑。净资产合计 = 25,000 英镑 + 60,740 英镑 = 85,740 英镑。该数字必须等于期末资本，即期初资本加净利润减提款。
10. Common Errors and How to Avoid Them | 常见错误与避免方法
In a mock test, many students lose marks by mixing up capital and revenue expenditure. For instance, a repair that extends the life of an asset should be capitalised, not written off as an expense. Always ask: 'Does this spending create a benefit beyond the current year?'
在模拟测试中，许多学生因混淆资本性支出与收益性支出而失分。例如，能延长资产使用寿命的维修应资本化，而不是作为费用冲销。永远要问：「这笔支出是否能在本年度之后带来收益？」
Another trap is forgetting to adjust for closing inventory. If closing inventory is overlooked, cost of sales will be overstated and gross profit understated. Double-check that the closing inventory figure appears both in the income statement (as a deduction from cost of sales) and in the statement of financial position (as a current asset).
另一个陷阱是忘记对期末存货进行调整。如果忽略了期末存货，销售成本会被高估，毛利会被低估。务必检查期末存货数字是否同时出现在损益表（作为销售成本的抵减）和资产负债表（作为流动资产）中。
Many also stumble on accruals. Remember: an accrued expense means the expense has been incurred but not yet paid, so you
