Calculation and written-answer questions

0:00 Calculation and written questions

Here's something examiners say again and again in their reports. Many candidates who lose marks on written questions actually knew the material. They just wrote generic points that could apply to any company, instead of applying their knowledge to the scenario in front of them. And on calculations, many marks are lost not through ignorance, but through a misread requirement or a wrong sign. In this lecture you'll learn a method for calculations, formula mastery, calculator skills, how to structure written answers, what command words demand, and how to use examiner reports.

0:40 Why it matters

Why does this matter? Because calculation and written questions often carry significant marks, and they reward method as well as final answers. In many exams, marks are available for correct workings and well-applied points, even if the final number or conclusion isn't perfect. That means a systematic approach earns marks reliably, while a rushed, unstructured answer throws them away. These are also the skills you'll use every day at work.

1:10 Calculation method

Here's the concept for calculations: ask, formula, substitute, calculate, sense-check, label. Ask: what exactly is required, including units, period, per unit or total, and rounding. Formula: write it before any numbers. Substitute step by step, labelling each figure. Calculate with your permitted calculator, keeping full precision until the end. Sense-check: is the sign right, is the size plausible, does it match the scenario's direction? And label with units and, if asked, a one-line interpretation. Here's the key idea: the method protects you when you're tired and under time pressure.

1:49 The pharmacist's routine

Here's an analogy. Think of a pharmacist making up a prescription. They don't eyeball it. They read the prescription carefully, check the formula and dose, measure step by step, check the result against what's plausible for this patient, and label the bottle clearly. A tiny error, a misplaced decimal point, can matter enormously, so the routine is always the same. Calculation questions deserve that pharmacist's discipline. And a sense-check is your final safety check before it goes to the patient.

2:24 Formulas and calculators

Formula mastery and calculator skills matter too. Understand formulas, not just memorise them: what each part means, and when the formula applies. Then write the key formulas from memory for five minutes daily, and check. Find out from the handbook which formulas the exam provides and which it doesn't. And practise with your permitted calculator model, not your phone. Learn its memory functions and key shortcuts. Many candidates lose time on exam day fumbling with an unfamiliar calculator.

2:58 Written answers

Now written answers. Start with the command word: explain, evaluate, recommend, discuss. Each demands something different. Explain means make clear why or how. Evaluate means weigh up strengths and weaknesses and reach a judgement. Recommend means propose a specific course of action with reasons. Then use the marks as a guide to depth: more marks usually means more distinct, developed points. Plan briefly, using headings that mirror the requirement. And for each point, use the pattern: point, apply it to the scenario, then the consequence or implication. Finish with a clear conclusion if one is asked for.

3:40 Worked example 1: CM ratio (illustrative)

A simple worked example. An illustrative calculation: find the contribution margin ratio, with sales of five hundred thousand and variable costs of three hundred thousand. Ask: a ratio, not an amount. Formula: sales minus variable costs, divided by sales. Substitute: five hundred thousand minus three hundred thousand, over five hundred thousand. Calculate: two hundred thousand divided by five hundred thousand is zero point four. Sense-check: between zero and one, and variable costs are below sales, so it's plausible. Label: forty per cent, meaning forty cents of each sales dollar contributes to fixed costs and profit.

4:21 Worked example 2: Lahore candidate (illustrative)

Now a realistic scenario, illustrative. A candidate in Lahore preparing for an ACCA-style written paper consistently scores low on written sections despite strong knowledge. Examiner reports for her paper say candidates often write generic points. She changes her approach. For every answer, she first lists three to five specific facts from the scenario she'll use. She uses headings that mirror the requirement. Each point follows point, apply, consequence. She ends with a clear recommendation. When she self-marks against model answers, she highlights sentences that use a scenario fact. Her highlighted share rises, and so do her practice marks, within a month.

5:05 Examiner reports

Examiner reports are one of the most underused resources in exam preparation. Many awarding bodies publish reports after each sitting, describing what good answers did, where candidates lost marks, and common misunderstandings. Read the reports for your paper, especially for question types you find hard. Keep a list of the repeated criticisms, such as not applying to the scenario, not answering the requirement, or poor time allocation, and check your practice answers against that list. It's like being told in advance what the examiner will be looking for.

5:43 Watch me: planning an 'evaluate' answer

Watch me do it. I plan an illustrative ten-mark evaluate question about whether a company should outsource its payroll. Command word: evaluate, so I need both sides and a judgement. Ten marks suggests around five developed points. Scenario hooks: frequent errors in payroll, one in-house specialist about to retire, and sensitive employee data. Headings: benefits, risks, conclusion. First point: reduced key-person risk, because the specialist is retiring, so continuity improves. Then a risk: data protection, because payroll data is sensitive, so due diligence on the provider is essential. Conclusion: outsource, with contract controls. Planning takes about two minutes.

6:26 AI feedback on written answers

Can AI help with written answers? It can be a useful practice partner. Paste the requirement and your own answer, and ask for feedback against specific criteria: did I use the command word correctly, did I apply each point to the scenario, is my conclusion clear, and what are the three most important improvements? That kind of structured feedback is valuable when you don't have a tutor. But remember two limits. AI feedback isn't the examiner's marking scheme. And never ask it to write your answer for you to memorise. The exam tests your ability to produce the answer, under time pressure, on your own.

7:12 Measuring improvement

How do you measure improvement? For calculations, track errors by type: misread requirement, formula error, arithmetic slip, sign error. For written answers, self-mark against model answers or marking guides, and track the share of your sentences that apply a scenario fact. Track time per mark, to make sure you're not over-writing early questions. And if you can get feedback from a tutor or peer who knows the marking approach, that's even better.

7:43 Common mistakes

Common mistakes. Jumping into numbers before reading the requirement. Not showing workings, so no method marks are possible. Rounding too early. Never sense-checking. Practising on a phone instead of the permitted calculator. In written answers: ignoring the command word, writing generic textbook points, one long paragraph with no structure, and no conclusion when one is asked for. And using AI-written model answers without checking them against official marking guides.

8:13 Recap and try this now

Let's recap. For calculations: ask, formula, substitute, calculate, sense-check, label. Master formulas through understanding and daily recall, and practise with your permitted calculator. For written answers: decode the command word, let marks guide depth, plan with headings, and use point, apply, consequence, with a clear conclusion. Read examiner reports. Your try this now: use the calculation routine and the written-answer template from the lesson on one practice question of each type today, then self-mark with the highlighting method. Next, we'll manage time in the exam.
