How to Get a 7 in IB Economics 15-Mark Essays

The 15-mark essay is where strong IB Economics students separate themselves from students who only know the theory. Marks come from a controlled structure, relevant diagrams, and evaluation that actually weighs the issue instead of listing disconnected pros and cons.

This guide works best alongside the evaluation phrases guide and the growth versus environment model essay so you can move from essay structure to actual exam-ready paragraphs.

The simplest 15-mark essay structure

1. Define the key terms from the question
2. Explain the core theory clearly
3. Use one relevant diagram and refer to it
4. Apply the argument to a real example or context
5. Evaluate with a balanced judgment
6. Conclude directly

What examiners reward

Examiners want one coherent line of reasoning. The answer should feel cumulative: definition, mechanism, diagram, application, judgment. If the paragraph order feels random, the mark usually stalls.

How to make evaluation score

• Use short run versus long run
• Compare different stakeholder groups
• Comment on the size of the effect
• Bring in country context or level of development
• Challenge unrealistic assumptions in the theory

How to plan quickly before writing

• Underline the command term
• Choose the diagram before you draft paragraph one
• Write one supporting point and one challenge to it
• Decide your final judgment before the main body

If you keep drifting into generic conclusions, borrow phrasing from the evaluation guide and then test that structure on the model essay.
