Confirm the title and session

Obtain the prescribed titles for your examination session through your school and choose one according to the task instructions. Preserve its wording. An interesting question from an older session or online list does not replace the assigned title. Read the title slowly and identify its main relationship, qualification and required areas of knowledge. The essay has a maximum length of 1,600 words. That limited space makes a focused argument important. Begin planning with what the title asks you to evaluate, not with a memorized essay formula.

Unpack the terms in context

Highlight words whose meaning affects the answer. Give them working meanings relevant to the title, then ask whether those meanings differ across your chosen contexts. Avoid opening with several dictionary definitions that never influence the argument. A definition earns space when it clarifies a distinction you use later. Identify assumptions in the title and conditions under which its central claim might hold. You do not need to reject the title's wording to think critically; you need to examine its implications precisely.

Choose cases for their analytical role

Select specific examples you understand and can verify. For each, identify the knowledge process, possible claim, supporting details and limitation. A famous event is useful only if it advances the title. Avoid collecting one example per paragraph before knowing what each will demonstrate. Choose cases that can support a meaningful comparison or qualification. Record source details for factual material. Hypothetical examples can help practice reasoning, but they should not be presented as historical or scientific evidence in the finished essay.

Try a worked planning distinction

For an original practice question about the usefulness of models, a student compares a physical model with a model of commuter choice. The plan first asks what usefulness means in each context: explanation, prediction or practical decision. It then identifies assumptions and circumstances in which each model performs poorly. The emerging judgment is conditional rather than simply 'models are useful.' This is an illustrative planning exercise, not an official prescribed title. Apply the same habit of clarifying the relationship and testing conditions to your actual title.

Organize the reasoning in a visible sequence

Write your provisional answer, then list the main steps supporting it. Give each section a purpose: establish a claim, examine a case, evaluate a qualification or compare consequences. Explain how one step leads to the next. There is no requirement to use a universal claim-counterclaim pattern, and a rigid pattern can create artificial opposition. Use a structure that keeps the exploration coherent. Reserve enough space for evaluating why a distinction matters rather than devoting most of the essay to describing examples.

Check the plan before drafting

Read the prescribed title beside every planned section. Ask how the section advances an answer and what it contributes beyond the previous one. Remove detours and unsupported broad claims. Check that the cases represent the chosen areas accurately and that the conclusion could follow from the reasoning. Discuss permitted planning questions with your teacher. Keep a record of substantive changes and the evidence for them. A good plan does not guarantee a grade; it gives you an argument you can test, draft and improve within the task's constraints.
