The Strong Conclusion

The conclusion is the last thing the examiner reads. It leaves the final impression. A weak conclusion can undermine an otherwise strong essay, while a confident, well-crafted conclusion can elevate a good essay to an excellent one.

Yet conclusions are often the most neglected part of Section B essays. Candidates run out of time, energy, or ideas, and end up with a limp final paragraph that merely repeats the introduction. This lesson teaches you how to write conclusions that draw threads together, reinforce your thesis with added nuance, and leave the reader with something to think about.

What a Conclusion Should Do

A strong Section B conclusion accomplishes three things:

Function	What It Involves
1. Synthesise	Draw together the key threads of your argument into a cohesive whole — not a list, but a unified position
2. Reinforce with nuance	Restate your thesis, but with the added depth that comes from having explored the arguments and counterarguments
3. Elevate	End with a forward-looking observation, a broader implication, or a thought-provoking reflection that gives the essay resonance

Key Point: The conclusion is not a summary. It is a synthesis. Summaries list what you have said; syntheses show how the different elements of your argument combine to support your position.

What a Conclusion Should NOT Do

Mistake	Why It Fails
Simply repeating the introduction	Adds nothing; wastes precious words; signals that you have nothing new to say
Introducing entirely new arguments	These should appear in the body of the essay; new points in the conclusion cannot be developed or supported
Undermining your own thesis	Ending with "but it's hard to say" or "both sides have valid points" without resolution leaves the reader feeling you have not committed to a position
Trailing off weakly	Endings like "In conclusion, this is a complex issue" or "Only time will tell" are vague and unsatisfying
Being excessively long	The conclusion should be 60–80 words in a 500–600 word essay — roughly the same length as the introduction

The Three-Part Conclusion Structure

Part 1: The Restated Thesis (with Added Nuance)

Restate your core position, but not in the same words as the introduction. The conclusion thesis should reflect what you have learned through writing the essay — the nuances, qualifications, and insights that emerged from engaging with arguments and counterarguments.

Introduction thesis:

"The government should introduce a sugar tax to reduce obesity."

Conclusion thesis (with nuance):

"While a sugar tax is not a complete solution to the obesity crisis, it represents a proportionate, evidence-based intervention that can meaningfully reduce consumption of the most harmful products — particularly when combined with investment in public health education."

Notice how the conclusion thesis is more qualified and more specific. It does not retreat from the position but demonstrates that the writer has grappled with the complexity of the issue.

Part 2: Drawing Threads Together

Briefly connect the key arguments you have made, showing how they reinforce each other:

"The public health evidence, the precedent set by tobacco taxation, and the principle that collective costs justify collective measures all point in the same direction."

This is not a list of everything you said. It is a single sentence that shows how the different strands of your argument converge.

Part 3: The Elevating Finish

End with something that gives the essay resonance beyond the specific question asked. This might be:

A broader implication:

"The sugar tax debate is ultimately a test case for a larger question: whether democratic societies can act on scientific evidence to protect public health, even when doing so requires confronting powerful commercial interests."

A forward-looking observation:

"If governments fail to act on clear evidence of harm in the case of sugar, it is difficult to see how they will find the political will to address more complex public health challenges in the decades ahead."

A thought-provoking reflection:

"In a society that regulates tobacco, alcohol, and pharmaceuticals, the absence of meaningful regulation of sugar content in processed food is less a principled stance than an historical accident — one that the evidence increasingly demands we correct."

Worked Examples

Example 1: Compulsory Voting

Question: "Should voting be compulsory?"

Weak conclusion:

"In conclusion, compulsory voting has both advantages and disadvantages. Some people think it is a good idea and some people do not. It is a complex issue with no easy answer."
