Write essays
that earn marks.
Written assessments don't have a quiz to fail first — so the standard Stack approach needs adapting. This guide shows you two simple techniques that fix the most common problems in student writing: thin content and shallow analysis. Use both together to produce richer, deeper, higher-scoring work.
/The two techniques you'll use
The first technique expands your content. The second deepens your analysis. Together they cover the two failure modes that lose the most marks in written work.
- The 5 Ws and 1 H — Who, What, Where, When, Why, How. Used to make sure you've covered every angle of a topic.
- The Why-Why-Why method — Ask "why" three to five times in a row to push past surface-level answers into real analysis.
/Technique 1: The 5 Ws and 1 H
This is borrowed from journalism. Reporters use it to make sure they cover every angle of a story. It works just as well for essays, reports, and coursework. Before you write a paragraph, run the six questions against your topic. Any unanswered question is a content gap.
The six questions
| Question | What it uncovers |
|---|---|
| Who | The people, organisations, groups, or stakeholders involved |
| What | The event, concept, action, or outcome you're discussing |
| Where | The location, context, sector, or setting |
| When | The time period, date, sequence, or duration |
| Why | The reasons, motives, causes, or drivers behind it |
| How | The process, mechanism, or method used |
Worked example — a business essay
Essay question: "Discuss the impact of remote working on small businesses."
If you start writing without the 5 Ws, you'll likely produce a vague paragraph along the lines of "Remote working has affected small businesses by changing how people work." Thin. Generic. Low marks.
Now run the questions:
Who: Small business owners, employees, customers, suppliers, IT providers.
What: A shift from office-based to home-based work, including hybrid models, full remote, and asynchronous teams.
Where: UK small businesses (under 50 staff), particularly in services, tech, consulting, and creative sectors.
When: Accelerated by Covid-19 in March 2020, but trend continues into 2026 with 38% of UK workers still hybrid (ONS).
Why: Cost savings on office space, employee preference for flexibility, talent access beyond local area, and technology making it viable.
How: Cloud platforms (Microsoft 365, Google Workspace), video conferencing, asynchronous tools (Slack, Notion), and updated HR policies.
Now you've got six clear angles. Each one becomes a paragraph or section. The essay writes itself.
Worked example — a history essay
Essay question: "Analyse the causes of the French Revolution."
Who: Louis XVI, Marie Antoinette, the Third Estate, the bourgeoisie, the peasants, Enlightenment thinkers (Voltaire, Rousseau).
What: A political and social upheaval that ended the absolute monarchy and led to the First Republic.
Where: France, with major events in Paris and Versailles. Spread to influence the rest of Europe.
When: 1789 to 1799, with key flashpoints including the storming of the Bastille (14 July 1789) and the execution of Louis XVI (1793).
Why: Financial crisis from war debt, regressive taxation falling on the poor, food shortages, growing influence of Enlightenment ideas, and an inflexible monarchy.
How: Through political protest, the Estates-General, the National Assembly, mob violence, and eventually military revolution.
How to use it in practice
- Read the question carefully and identify the topic
- Write the 5 Ws and 1 H down the side of a blank page
- Fill in each one with what you know — cold, no research yet
- Spot the gaps — any question you can't answer becomes a research target
- Research only what's needed to fill the gaps
- Use the filled-in answers as the skeleton of your essay
/Technique 2: The Why-Why-Why method
This one comes from root cause analysis — originally used by Toyota to find the real reason behind manufacturing problems. The principle: the first answer is rarely the deepest. Keep asking "why" and you uncover the layers underneath. In essay writing, it forces you past surface-level statements into proper analysis.
You ask "why" three to five times. Each answer leads to the next question. By the fifth round, you've usually arrived at a much more interesting and original point than where you started.
Worked example — a business essay
Surface statement: "Remote working has reduced office costs for small businesses."
Why has it reduced costs? Because businesses need less physical office space.
Why does that reduce costs? Because they can downsize to smaller offices or shared workspaces, cutting rent, rates, and utilities.
Why is that significant for small businesses specifically? Because office rent is often one of the top three fixed costs for a small business, second only to wages and stock.
Why does that matter strategically? Because cutting fixed costs gives small businesses more cash flow flexibility, allowing them to weather downturns or invest in growth.
Why is that especially important now? Because UK small businesses face rising costs from inflation, energy prices, and tax changes — making flexible cost structures essential for survival.
Notice how the final point is far more sophisticated than where you started. That's the kind of analysis that earns top marks.
Worked example — a literature essay
Surface statement: "Lady Macbeth is ambitious."
Why is she ambitious? Because she pushes Macbeth to kill Duncan and seize the throne.
Why does she push so hard? Because she believes Macbeth lacks the ruthlessness to act on his own desire.
Why does she believe that? Because she sees his hesitation as weakness, while she equates ruthlessness with masculinity and strength.
Why does she equate masculinity with strength? Because in the gender norms of the play, women lack the power to act — so she must channel "unsexed" male traits to achieve her goals.
Why does this matter to the play's meaning? Because it shows ambition isn't just a character flaw — it's a response to a power structure that denies her direct agency. Her tragedy becomes a tragedy of gender as much as of ambition.
You've gone from a one-line observation to a layered argument that connects character, theme, and historical context. That's the difference between a C and an A.
Worked example — a science report
Surface statement: "The experiment showed that plants grow taller in red light."
Why did they grow taller in red light? Because red light triggers a specific growth response in plants.
Why does red light specifically? Because chlorophyll absorbs red wavelengths most efficiently for photosynthesis.
Why does more efficient photosynthesis lead to taller growth? Because it produces more glucose, which fuels cell division and stem elongation.
Why might that matter practically? Because commercial growers can use red LED lighting to accelerate growth in indoor farms, reducing time-to-harvest.
Why is this commercially significant? Because faster harvest cycles mean higher annual yields, lower energy costs per unit of food produced, and a smaller environmental footprint compared to outdoor farming.
How to use it in practice
- Write your first surface-level statement at the top of a page
- Underneath, write "Why?" and answer it in one sentence
- Take your answer. Ask "Why?" again. Answer it.
- Repeat three to five times
- The final answer is usually your best paragraph or thesis point
- Use the chain of answers as the structure of your analysis
/Combining both techniques
The two techniques work best together. Use the 5 Ws to map out your content. Use Why-Why-Why to deepen each point.
Here's the workflow:
- Read the question and identify the topic
- Use the 5 Ws to generate six angles — this becomes your essay structure
- For each angle, write a surface-level statement
- Run Why-Why-Why on each statement to build out the analysis
- You now have a fully mapped essay with both breadth (5 Ws) and depth (Why-Why-Why)
- Draft, then check against the marking rubric
/Where this fits in The Stack
These techniques live inside Scenario 5 of The Stack Guide (the written assessments scenario). They're the "research and analysis" step that comes after your cold draft and before your final write-up.
- After your cold draft (your fail-first equivalent for writing), use the 5 Ws to identify which angles you missed
- Before your final draft, use Why-Why-Why to deepen the analysis in your weakest paragraphs
- For revision, build Anki cards for the key concepts, theorists, and evidence uncovered by both techniques
/Common mistakes
- Using the 5 Ws as a checklist without actually integrating the answers into your writing
- Stopping at the second "why" — the gold is usually at the fourth or fifth
- Applying Why-Why-Why without evidence — each layer still needs supporting facts, quotes, or data
- Treating these as a replacement for research — they're tools to organise and deepen research, not skip it
- Skipping the marking rubric — both techniques help you produce more content, but the rubric tells you what content earns marks
/ The two-line summary
5 Ws stops your essay being thin. Why-Why-Why stops your analysis being shallow. Run both before every written assessment and your work moves up a grade.
