The 20+ Mark Essay

The 20-mark essay (or its equivalent: 16-mark, 25-mark, or 30-mark depending on the subject and board) is the centrepiece of most A-Level exams. It is where the most marks are concentrated, where the widest range of skills is tested, and where the biggest differences between grades emerge. Mastering the extended essay is the single most impactful thing you can do for your A-Level results.

The Structure That Works

After years of examining, marking, and teaching, one essay structure consistently delivers top-band results across virtually all A-Level subjects:

flowchart TD
    A[Introduction<br/>Thesis statement + signpost<br/>2-3 sentences] --> B[Body Paragraph 1<br/>Strongest argument FOR<br/>Point + Evidence + Analysis + Evaluation]
    B --> C[Body Paragraph 2<br/>Supporting argument<br/>Point + Evidence + Analysis + Evaluation]
    C --> D[Body Paragraph 3<br/>Counter-argument<br/>Challenges or alternative perspective]
    D --> E[Body Paragraph 4<br/>Response to counter / Additional nuance<br/>Optional but adds sophistication]
    E --> F[Conclusion<br/>Weigh arguments + Justified judgement<br/>3-5 sentences]

The Introduction (2-3 minutes)

Your introduction should do three things in 2-3 sentences:

1. Address the question directly — show you have understood precisely what is being asked
2. State your thesis — your overall argument or position
3. Signal the complexity — acknowledge that the issue is not straightforward

Template: "While [Factor A] was undoubtedly significant in [the topic of the question], it can be argued that [Factor B] was ultimately more important because [brief reason]. This essay will examine both factors, alongside [Factor C], before reaching a judgement."

Body Paragraphs (4-5 minutes each)

Each body paragraph should follow an extended PEEL structure:

Element	Purpose	Approximate Length
Point	State the argument for this paragraph	1 sentence
Evidence	Provide specific supporting evidence	1-2 sentences
Explanation	Explain HOW the evidence supports the point	2-3 sentences
Evaluation	Critically assess the point — limitations, counter-evidence, conditions	2-3 sentences
Link	Connect back to the question and to your overall thesis	1 sentence

The evaluation within each paragraph is what separates Band 3 from Band 5. Band 3 essays evaluate at the end. Band 5 essays evaluate as they go — every paragraph contains both analysis and critical assessment.

The Conclusion (2-3 minutes)

Your conclusion must:

1. Directly answer the question — not "it depends" but a clear position
2. Weigh the arguments — explain why some arguments are stronger than others
3. Acknowledge nuance — show that you understand the issue has complexity
4. Avoid introducing new evidence — synthesise what you have already written

Time Management for the Extended Essay

For a 20-mark essay with approximately 25 minutes:

Phase	Time	What to Do
Planning	3-4 min	Brainstorm points, select strongest 3-4, decide thesis and conclusion
Introduction	2 min	Thesis, direction, scope
Body paragraphs	15-16 min	3-4 paragraphs of ~4 min each
Conclusion	3 min	Judgement, weighing, nuance
Quick check	1 min	Terminology, SPaG, missed points

The 3-Minute Plan

Before writing, spend 3 minutes on a brief plan:

1. Draw a quick table: "For | Against | Conclusion"
2. List 2-3 points on each side with one piece of evidence each
3. Decide which side is stronger and why — this becomes your thesis and conclusion
4. Number your points in the order you will write them (strongest first)

This plan costs 3 minutes but saves more than that by preventing waffle, repetition, and structural problems.
