Essay Section B, decoded

The official ideal is about 500500-600600 words. Universities receive the essay directly, and each decides how to use it. Clear reasoning matters more than legal knowledge or decorative vocabulary.

Know the job before choosing the topic

Section B gives you 4040 minutes to answer one of three prompts. The essay should demonstrate economical argument and reach a conclusion. The board's own guidance puts the ideal at 500500-600600 words and warns that very long essays disadvantage candidates; it publishes no maximum.

You may state assumptions instead of carrying a warehouse of facts. Name the assumption and show the reasoning it supports.

The split is a practice rule rather than an official rubric. Adjust it only after timed evidence shows where your argument currently collapses.

Build a plan that can change your mind

Worked example Should public debate protect offensive speech?

Define the claim

Protection means a strong presumption against punishment by public authorities. Offensive covers expression that wounds or alarms without directly threatening unlawful harm.

Reason one

Authorities can stretch vague offence rules against unpopular minorities, so broad power creates a risk of selective enforcement.

Strongest objection

Repeated degrading speech can exclude people from public life even without a direct threat, so unrestricted protection can hollow out equal participation.

Reply and judgement

Protect offence alone, while allowing narrow rules for threats, targeted harassment and conduct that blocks equal access. The judgement is strong but conditional.

Why this works: The final position becomes more precise after meeting the strongest objection.

Why the tempting route fails: Listing one argument on each side and ending with 'both have a point' leaves the disputed boundary undecided.

Make every paragraph prove something

  1. Claim: what should the reader accept by the end of this paragraph?
  2. Reason: why does the claim follow?
  3. Example or assumption: what concrete case makes the reason testable?
  4. Link: how does this change the overall judgement?
  • Cut background that never enters the reasoning.
  • Replace three undeveloped examples with one example whose relevance you explain.
  • Remove repeated topic sentences and intensifiers.
  • Check that the conclusion states the condition controlling your extent of agreement.
