Assessment objectives: AO1 Knowledge and understanding 66%, AO2 Analysis 24%, AO3 Evaluation 10%. This is a knowledge- and technique-heavy subject: accuracy of layout and method matters more than argument.

Presentation earns marks. Use the correct heading (name of business, name of statement, and the date or period), rule your columns, put figures in the right column, and show your workings. A correct figure in the wrong column often scores nothing.
The one rule everything depends on

Double entry — quick reference

The golden ruleEvery transaction has two entries of equal value: one debit and one credit. Total debits must always equal total credits.
Debit the account that receives value (or where an asset or expense increases). Credit the account that gives value (or where a liability, capital or income increases).
Account typeIncreaseDecrease
Asset (machinery, inventory, bank, receivables)DebitCredit
Expense (rent, wages, insurance)DebitCredit
Liability (loan, payables)CreditDebit
CapitalCreditDebit
Income (sales, rent received)CreditDebit

A memory aid: DEAD CLICDebit Expenses, Assets, Drawings; Credit Liabilities, Income, Capital.

Worked example

Record these transactions: (a) the owner pays $20 000 into the business bank account; (b) goods bought on credit from Khan for $3000; (c) rent paid by cheque $800; (d) goods sold for cash $1200.

TransactionDebitCredit
(a) Owner invests $20 000Bank $20 000 (asset up)Capital $20 000
(b) Credit purchase $3000Purchases $3000Khan (payable) $3000 (liability up)
(c) Rent paid $800Rent $800 (expense up)Bank $800
(d) Cash sales $1200Cash $1200Sales $1200 (income up)
Confusing drawings with an expense. Drawings are the owner taking value out of the business — debit Drawings, credit Bank/Purchases. Drawings are deducted from capital in the statement of financial position, and never appear in the income statement.

The fundamentals of accounting

1.1The purpose of accounting 1.2The accounting equation

Book-keeping vs accountingBook-keeping is the detailed recording of all financial transactions. Accounting uses those records to prepare and interpret financial statements. Book-keeping records; accounting explains.

Purposes: to record transactions accurately, to calculate profit or loss, to show the financial position of the business, to help owners make decisions and control the business, and to provide information for other interested parties.

Assets = Capital + Liabilities
(and therefore Capital = Assets − Liabilities)

Every transaction keeps the equation in balance — that is exactly why double entry works.

Worked example

A business has assets of $85 000 and liabilities of $32 000. Find the capital. The owner then introduces a further $10 000 cash. Show the effect.

  1. Capital = Assets − Liabilities = 85 000 − 32 000 = $53 000
  2. New cash raises assets to $95 000 and capital to $63 000; liabilities unchanged at $32 000
  3. Check: 95 000 = 63 000 + 32 000 ✓ — the equation still balances
Skill check: A business buys a vehicle for $12 000 on credit. State the effect on assets, liabilities and capital.
Solution: Assets increase by $12 000 (the vehicle) and liabilities increase by $12 000 (amount owed to the supplier). Capital is unchanged — the owner has invested nothing new. The equation still balances.

Sources and recording of data

2.1The double entry system of book-keeping

Entries are made in ledger accounts, traditionally in "T" format with debits on the left and credits on the right. The ledger is divided into:

DivisionContains
Sales ledgerPersonal accounts of credit customers (trade receivables)
Purchases ledgerPersonal accounts of credit suppliers (trade payables)
Nominal (general) ledgerAll other accounts — income, expenses, assets, capital

Balancing an account: total both sides, insert the balancing figure as "Balance c/d" on the smaller side, total both sides to the same figure, and bring the balance down as "Balance b/d" on the opposite side below the totals.

Understand also the treatment of discounts: a cash (settlement) discount is for prompt payment and is recorded in the accounts (discount allowed is an expense, discount received is income); a trade discount is a reduction off the list price and is never recorded — the transaction is simply entered at the net figure.

Recording trade discount in the ledger. It is deducted before the entry is made, so it never appears in any account. Only cash/settlement discounts are recorded.

2.2Business documents 2.3Books of prime entry

DocumentPurposeRecorded in
InvoiceRequests payment for goods sold on creditSales journal / purchases journal
Credit noteIssued for returns or overchargesSales returns / purchases returns journal
Debit noteRequest to a supplier for a credit note
Statement of accountSummary of a customer's transactions for the month
Cheque counterfoil / receiptEvidence of payment made or receivedCash book
Book of prime entryRecords
Sales journalCredit sales
Purchases journalCredit purchases
Sales returns journalGoods returned by customers
Purchases returns journalGoods returned to suppliers
Cash bookAll receipts and payments (it is both a book of prime entry and a ledger account)
Petty cash bookSmall cash payments, usually on the imprest system
General journalEverything else: opening entries, purchase/sale of non-current assets on credit, corrections of errors, year-end transfers
The imprest systemA fixed float is set (say $200). At the end of the period the petty cashier is reimbursed exactly the amount spent, restoring the float to $200. Advantages: spending is controlled, and the totals are easy to check.

Verification of accounting records

3.1The trial balance

A trial balance lists every ledger balance at a date, in debit and credit columns. Its purposes: to check the arithmetical accuracy of the double entry, and to provide a starting point for the financial statements.

Which side? Debit balances: assets, expenses, drawings, purchases, returns inwards. Credit balances: capital, liabilities, income, sales, returns outwards, provisions and allowances.

A balanced trial balance does not prove the books are correct — six types of error do not affect agreement at all (see 3.2). Saying "the trial balance balances so there are no errors" is wrong and is regularly tested.

3.2Correction of errors

Errors NOT revealed by the trial balanceMeaning
OmissionA transaction completely left out of the books
CommissionCorrect amount, correct side, but in the wrong person's account of the same type
PrincipleEntered in the wrong class of account (e.g. a machine debited to Repairs)
Original entryThe wrong amount entered on both sides
Complete reversalThe correct amount, but debit and credit the wrong way round
CompensatingTwo errors of equal value on opposite sides that cancel out

Errors that do affect agreement (one-sided errors, wrong additions, an entry on the wrong side) are corrected through a suspense account, which is opened for the difference and closed once all corrections are posted.

Worked example

A machine costing $5000 was debited to the Repairs account. Correct the error and state its type.

  1. Type: error of principle — capital expenditure treated as revenue expenditure.
  2. Correcting journal entry: Debit Machinery $5000, Credit Repairs $5000.
  3. Effect on profit: repairs were overstated by $5000, so profit was understated by $5000; correcting it increases profit by $5000, and non-current assets rise by $5000.
Correction questions almost always ask for the effect on profit as well as the journal entry. Work it out by asking: was an expense or income wrongly included or excluded, and by how much? Set out your answer as a statement of corrected profit, showing each adjustment as an addition or subtraction.

3.3Bank reconciliation

The cash book balance and the bank statement balance differ because of timing differences and items the business does not yet know about.

Method — two stages, in this order
  1. Update the cash book for items on the statement that are not yet in the books: bank charges, interest, direct debits and standing orders, credit transfers received, dishonoured cheques, and any errors made by the business.
  2. Prepare the reconciliation statement for timing differences and bank errors:
    updated cash book balance + uncredited deposits (lodgements not yet on the statement) − unpresented cheques = bank statement balance.
Worked example

The cash book shows $4200 debit. Bank charges of $150 have not been recorded. Unpresented cheques total $900 and deposits not yet credited total $1300. Prepare the reconciliation.

  1. Updated cash book = 4200 − 150 = $4050
  2. Reconciliation: 4050 + 1300 (uncredited deposits) − 900 (unpresented cheques) = $4450 per the bank statement

3.4Control accounts

A sales ledger control account summarises all transactions with credit customers; a purchases ledger control account does the same for credit suppliers. Their balances should equal the total of the individual accounts in that ledger — providing a check on accuracy and helping to locate errors quickly.

Sales ledger control account
Debit side (increases owed to us)Opening balance, credit sales, dishonoured cheques, interest charged
Credit side (reductions)Receipts from customers, discount allowed, sales returns, irrecoverable debts written off, contra/set-off
Worked example

Opening trade receivables $18 000; credit sales $95 000; receipts from customers $88 000; sales returns $2500; discount allowed $1200; irrecoverable debts written off $800. Find the closing balance.

  1. Debits: 18 000 + 95 000 = 113 000
  2. Credits: 88 000 + 2500 + 1200 + 800 = 92 500
  3. Closing balance = 113 000 − 92 500 = $20 500

Digital recording reduces arithmetical errors and produces control account totals automatically, but the principle of checking remains — data entry errors and fraud are still possible.

Accounting procedures

4.1Capital and revenue expenditure and receipts

CapitalRevenue
ExpenditureBuying or improving a non-current asset, plus the costs of getting it ready for use (delivery, installation, legal fees). Shown in the statement of financial position.Day-to-day running costs — repairs, fuel, wages, insurance. Shown in the income statement.
ReceiptsFrom selling a non-current asset, or from capital introduced or a loan receivedFrom normal trading — sales, rent received, commission received
Treating an improvement as a repair. Repainting a van is revenue expenditure; fitting a refrigeration unit that extends what the van can do is capital. Misclassifying this both misstates profit and misstates non-current assets — which is why it is such a popular exam question.

4.2Depreciation and disposal of non-current assets

DefinitionDepreciation is the allocation of the cost of a non-current asset over its useful life. It is not a way of saving cash to replace the asset, and it is not a valuation. It applies the matching (accruals) concept.

Causes: physical wear and tear, passage of time, obsolescence, and depletion.

MethodCalculationSuits
Straight line(cost − residual value) ÷ useful life, or a fixed % of costAssets used evenly, e.g. buildings, fixtures
Reducing balanceA fixed % of the net book value each yearAssets losing value fastest early on, e.g. vehicles, IT
RevaluationValue at start + purchases − value at endMany small items, e.g. loose tools
Worked example — both methods

A machine costs $20 000 with a residual value of $2000 and a useful life of 4 years. Compare straight line with reducing balance at 25%.

  1. Straight line: (20 000 − 2000) ÷ 4 = $4500 per year, every year.
  2. Reducing balance at 25%: Year 1 = 25% × 20 000 = $5000 (NBV $15 000); Year 2 = 25% × 15 000 = $3750 (NBV $11 250); Year 3 = 25% × 11 250 = $2812.50 (NBV $8437.50).
  3. Reducing balance charges more in early years, which better matches assets that lose value quickly.
Worked example — disposal

A vehicle costing $16 000 with accumulated depreciation of $11 000 is sold for $4000. Calculate the profit or loss on disposal.

  1. Net book value = 16 000 − 11 000 = $5000
  2. Proceeds $4000 − NBV $5000 = loss on disposal of $1000, charged to the income statement
  3. Entries: debit Disposal with cost, credit Disposal with accumulated depreciation and with proceeds; the balance is the profit or loss.

4.3Other payables and other receivables

Accruals and prepaymentsAn accrued expense (other payable) is an expense incurred but not yet paid — add it to the expense in the income statement and show it as a current liability.
A prepaid expense (other receivable) is paid in advance for a future period — subtract it from the expense and show it as a current asset.
Worked example

Rent paid during the year was $11 000. Rent owing at the year end is $1500; there was a prepayment of $800 at the start of the year. Find the charge to the income statement.

  1. Start with cash paid: $11 000
  2. Add the opening prepayment (it relates to this year): + $800
  3. Add the closing accrual (this year's expense, unpaid): + $1500
  4. Charge to income statement = $13 300; the $1500 also appears as an other payable under current liabilities.

4.4Irrecoverable debts and allowance for irrecoverable debts

An irrecoverable debt (bad debt) is one the business is certain it will not collect — write it off: debit Irrecoverable debts, credit the customer's account. A recovery of a debt previously written off is credited to income.

Allowance for irrecoverable debtsAn estimate of receivables that may not be collected. It applies the prudence concept — profits and assets should not be overstated.
Only the change in the allowance goes to the income statement: an increase is an expense; a decrease is added to income. The full allowance is deducted from trade receivables in the statement of financial position.
Worked example

Trade receivables at the year end are $40 000 after writing off $1000 of irrecoverable debts. The allowance is to be 3% of receivables; last year's allowance was $900. Show the treatment.

  1. Required allowance = 3% × 40 000 = $1200
  2. Increase in allowance = 1200 − 900 = $300 → charged as an expense in the income statement
  3. Income statement also shows the $1000 irrecoverable debts written off
  4. Statement of financial position: trade receivables 40 000 − 1200 = $38 800
Charging the whole allowance to the income statement each year. Only the movement goes there — the full figure is only used to reduce receivables in the statement of financial position.

4.5Valuation of inventory

The ruleInventory is valued at the lower of cost and net realisable value. Net realisable value = expected selling price − costs necessary to make the sale. This applies the prudence concept.
Worked example

Inventory item A cost $5000 and could be sold for $7000. Item B cost $3000 but is damaged; it can be sold for $2600 after $300 of repairs. Value the inventory.

  1. A: cost $5000 vs NRV $7000 → take the lower = $5000
  2. B: cost $3000 vs NRV = 2600 − 300 = $2300 → take the lower = $2300
  3. Total inventory value = $7300

Effect of an error: overvaluing closing inventory overstates profit for the year (cost of sales is understated) and overstates current assets — and it then understates next year's profit, because closing inventory becomes next year's opening inventory.

Preparation of financial statements

5.1Sole traders

Income statement format — learn this order
Revenue − Sales returns = Net revenue − Cost of sales (opening inventory + purchases − purchases returns + carriage inwards − closing inventory) = GROSS PROFIT + Other income (rent received, discount received) − Expenses (wages, rent, insurance, depreciation, irrecoverable debts, carriage outwards) = PROFIT FOR THE YEAR
Carriage inwards (cost of getting goods in) belongs in cost of sales. Carriage outwards (delivering to customers) is an expense below gross profit. Swapping them changes the gross profit and costs several marks.
Statement of financial position format
Non-current assets (at cost − accumulated depreciation = net book value) + Current assets (inventory, trade receivables less allowance, other receivables, bank, cash) = TOTAL ASSETS Capital at start + Profit for the year − Drawings = Capital at end + Non-current liabilities (long-term loan) + Current liabilities (trade payables, other payables, bank overdraft) = TOTAL CAPITAL AND LIABILITIES (must equal total assets)
Worked example

Revenue $120 000; opening inventory $8000; purchases $70 000; closing inventory $10 000; expenses $25 000. Calculate gross profit and profit for the year.

  1. Cost of sales = 8000 + 70 000 − 10 000 = $68 000
  2. Gross profit = 120 000 − 68 000 = $52 000
  3. Profit for the year = 52 000 − 25 000 = $27 000

5.2Partnerships

A partnership agreement sets out profit-sharing ratios, salaries, interest on capital and interest on drawings. Without an agreement, the default is that profits and losses are shared equally with no salaries or interest.

The appropriation account
Profit for the year + Interest on drawings − Partners' salaries − Interest on capital = Residual profit, shared in the profit-sharing ratio
Capital accounts record permanent capital and stay fixed. Current accounts record the year's share of profits, salaries and interest less drawings — a debit balance on a current account means the partner has taken out more than they earned.
Worked example

Profit for the year is $60 000. A and B share profits 3 : 2. A receives a salary of $10 000; interest on capital is $4000 for A and $3000 for B. Show the appropriation.

  1. Profit available: 60 000 − 10 000 (salary) − 4000 − 3000 (interest) = $43 000 residual
  2. A's share = 3/5 × 43 000 = $25 800; B's share = 2/5 × 43 000 = $17 200
  3. Total credited to A = 10 000 + 4000 + 25 800 = $39 800; to B = 3000 + 17 200 = $20 200
  4. Check: 39 800 + 20 200 = 60 000 ✓

5.3Limited companies

TermMeaning
Ordinary sharesCarry voting rights; dividends vary with profit; paid last
Preference sharesFixed rate of dividend, paid before ordinary shareholders; usually no votes
DebenturesLong-term loans, not shares. Interest is an expense in the income statement and must be paid whether or not there is profit
Retained earningsAccumulated profits not distributed as dividends
General reserveProfit transferred and set aside for future use
Treating dividends as an expense. Dividends are an appropriation of profit, shown after profit for the year — not in the income statement. Debenture interest, by contrast, is an expense. Getting these the wrong way round is one of the most common errors in company questions.
Capital employed = issued shares + reserves + non-current liabilities

5.4Manufacturing accounts

Structure
Direct materials consumed (opening raw materials + purchases − closing raw materials) + Direct labour + Direct expenses = PRIME COST + Factory overheads (indirect labour, factory rent, factory depreciation, power) + Opening work in progress − Closing work in progress = COST OF PRODUCTION
The cost of production then replaces "purchases" in the trading section of the income statement.
Worked example

Opening raw materials $6000; purchases of raw materials $34 000; closing raw materials $5000; direct labour $22 000; factory overheads $15 000; opening work in progress $3000; closing work in progress $4000. Find prime cost and cost of production.

  1. Direct materials consumed = 6000 + 34 000 − 5000 = $35 000
  2. Prime cost = 35 000 + 22 000 = $57 000
  3. Cost of production = 57 000 + 15 000 + 3000 − 4000 = $71 000

Subscriptions are the classic difficulty: only the amount relating to the current year goes to the income and expenditure account. Subscriptions received in advance are a liability; subscriptions owing (in arrears) are an asset. Trading activities such as a refreshment bar are shown separately, with only the profit transferred to the income and expenditure account.

5.6Incomplete records

The three standard techniques
  1. Profit from capital: profit = closing capital − opening capital + drawings − capital introduced.
  2. Missing figures from control accounts: reconstruct the sales or purchases ledger control account to find credit sales or credit purchases.
  3. Using margins and mark-ups: to find missing sales, purchases or inventory figures.
mark-up = gross profit ÷ cost of sales × 100  ·  margin = gross profit ÷ revenue × 100
Worked example

A trader's capital was $30 000 at the start and $46 000 at the end of the year. Drawings were $12 000 and capital introduced was $5000. Calculate the profit.

  1. Profit = closing capital − opening capital + drawings − capital introduced
  2. = 46 000 − 30 000 + 12 000 − 5000 = $23 000
Worked example — mark-up

Cost of sales is $40 000 and the business uses a mark-up of 25%. Find revenue and gross profit.

  1. Gross profit = 25% × 40 000 = $10 000
  2. Revenue = 40 000 + 10 000 = $50 000
  3. (Note the margin here is 10 000 ÷ 50 000 = 20% — mark-up and margin are not the same.)
Confusing mark-up (on cost) with margin (on selling price). A 25% mark-up equals a 20% margin. Read carefully which one the question gives you.
Given in the syllabus — learn them anyway

Every ratio formula

6.1Calculating ratios 6.2Interpretation

RatioFormulaWhat a change suggests
Gross profit margin (%)(gross profit ÷ revenue) × 100Falling → selling prices cut, or cost of sales risen (supplier prices, theft, wrong inventory valuation)
Mark-up (%)(gross profit ÷ cost of sales) × 100The same information expressed on cost rather than on revenue
Profit margin (%)(profit for the year ÷ revenue) × 100Falling while gross margin steady → expenses have risen
Return on capital employed (%)(profit before interest ÷ capital employed) × 100
capital employed = issued shares + reserves + non-current liabilities
How efficiently the capital invested generates profit; compare with interest rates and with other firms
Current (working capital) ratiocurrent assets ÷ current liabilitiesToo low → may not meet short-term debts; too high → cash or inventory used unproductively
Acid test (liquid) ratio(current assets − inventory) ÷ current liabilitiesLiquidity ignoring inventory, which may be slow to sell
Rate of inventory turnover (times)cost of sales ÷ average inventoryHigher → stock sells faster; falling → obsolete or overstocked goods
Inventory turnover (days)(average inventory ÷ cost of sales) × 365Average days stock is held
Trade receivables turnover (days)(trade receivables ÷ credit sales) × 365Rising → customers paying more slowly; credit control weakening
Trade payables turnover (days)(trade payables ÷ credit purchases) × 365Rising → taking longer to pay suppliers; may risk losing discounts or goodwill
Worked example

Revenue $250 000; cost of sales $150 000; profit for the year $40 000; capital employed $200 000; average inventory $25 000; trade receivables $30 000 (all sales on credit); current assets $70 000; current liabilities $35 000. Calculate and interpret.

  1. Gross profit = 250 000 − 150 000 = $100 000 → gross margin = 40%
  2. Profit margin = 40 000 ÷ 250 000 × 100 = 16%
  3. ROCE = 40 000 ÷ 200 000 × 100 = 20% — a strong return versus bank interest
  4. Current ratio = 70 000 ÷ 35 000 = 2 : 1 — healthy liquidity
  5. Rate of inventory turnover = 150 000 ÷ 25 000 = 6 times a year (about every 61 days)
  6. Trade receivables turnover = 30 000 ÷ 250 000 × 365 = 44 days — slow if the stated credit period is 30 days, so credit control should be tightened
Never stop at the number. Every ratio question carries marks for interpretation: state whether it has improved or worsened, give a plausible reason, and suggest an action. "Receivables days rose from 32 to 44, so customers are paying more slowly, which strains cash flow; the business should send statements promptly and offer settlement discounts."

6.3Inter-business comparison 6.4Interested parties 6.5Limitations

Comparisons are only meaningful between businesses of similar size, in the same industry, using similar accounting policies, and for the same time period.

Interested partyWhat they want to know
Owners / shareholdersProfitability and return on their investment
ManagersPerformance, to plan and control
Banks and lendersLiquidity and ability to repay
SuppliersWhether they will be paid, and how quickly
CustomersWhether the business will continue supplying them
EmployeesJob security and prospects for pay rises
Government / tax authoritiesTax payable and compliance

Limitations of accounting statements: figures are historical and may not indicate the future; they ignore non-financial factors (staff skill, reputation, location, competition); different accounting policies (such as depreciation method) make comparison difficult; inflation distorts figures over time; and one year's figures may be untypical.

Accounting concepts, ethics and technology

7.1Accounting concepts

ConceptMeaningApplied in
Business entityThe business is separate from its ownerDrawings recorded separately from expenses
ConsistencyThe same accounting treatment is used each yearKeeping the same depreciation method
DualityEvery transaction has two effectsDouble entry itself
Going concernThe business will continue for the foreseeable futureAssets valued at cost, not break-up value
Historic costAssets recorded at their original costNon-current assets in the statement of financial position
Matching (accruals)Income and expenses recorded in the period they relate to, not when cash movesAccruals, prepayments, depreciation
MaterialitySmall items need not be treated strictlyWriting off a cheap stapler rather than depreciating it
Money measurementOnly items measurable in money are recordedStaff loyalty and reputation are excluded
PrudenceDo not overstate profits or assets; provide for foreseeable lossesAllowance for irrecoverable debts; inventory at lower of cost and NRV
RealisationRevenue is recognised when the goods or services change hands, not when cash is receivedCredit sales recorded at the date of sale
Questions frequently ask you to name the concept being applied by a treatment. Work backwards: "inventory at the lower of cost and net realisable value" → not overstating assets → prudence. "Depreciation charged although no cash is paid" → expense matched to the period benefiting → matching/accruals.

7.2Ethical considerations 7.3Technology and sustainability

Ethical principles for accountants: integrity (honest and straightforward), objectivity (no bias or undue influence), professional competence and due care (keeping skills current and working carefully), confidentiality (not disclosing client information), and professional behaviour (complying with laws and avoiding anything that discredits the profession).

Why it matters: financial statements are relied on by lenders, investors, employees and tax authorities. Manipulating figures — overvaluing inventory, hiding liabilities, recording fictitious sales — misleads those users, can amount to fraud, and destroys trust in the business and the profession.

Technology in accounting — benefitsRisks and limitations
Faster and more accurate processing; automatic totals and control accounts; instant reports; less physical storage; easier back-up and remote access; automatic ratio calculationCost of systems and training; risk of data loss, hacking or fraud; errors in data entry still produce wrong results; staff may need retraining or become redundant; dependence on power and internet

Sustainability increasingly affects accounting: businesses report on environmental and social impact alongside financial results, reduce paper through digital records, and consider the long-term costs of environmental damage. This gives users a fuller picture than profit alone.

Skill check: A manager asks the accountant to value closing inventory above cost so that reported profit looks better before a loan application. Explain which ethical principles are breached and the likely consequences.
Solution: This breaches integrity (the accountant would not be honest), objectivity (they would be improperly influenced by the manager) and professional behaviour (it may be fraudulent). It also breaks the prudence concept and the rule that inventory is valued at the lower of cost and net realisable value. Consequences: the bank would lend on false information; when the overvaluation reverses, next year's profit is understated; the business could face legal action and lose the bank's trust, and the accountant could lose their professional standing.

How to revise this subject

  1. Master the double-entry rule first. Everything else — ledgers, trial balance, control accounts, corrections — depends on it. Drill it until it is instant.
  2. Learn the statement formats by writing them out blank, from memory, once a week: income statement, statement of financial position, appropriation account.
  3. Do full questions to time. Paper 2 is 100 marks in 105 minutes — roughly a mark a minute, so speed of layout matters as much as understanding.
