Your exam technique

Select the major features → compare accurately → remove unsupported interpretations.

Select a useful organising principle

High-quality reporting makes the most important features easy to see. Group categories by a shared pattern or a useful contrast, then support the overview with enough evidence. Do not let a long list of figures obscure the larger changes.

Respect what the data cannot show

Two observations show a change between points, not a steady change throughout the period. Avoid steadily unless intermediate observations support it. Keep the measure clear and distinguish a change in percentage points from a proportional change. Check that every comparison uses compatible units and periods.

Avoid this common mistake

Two endpoints do not show that a change was steady. Check each adjective and comparison against the information actually supplied, including the limits of that information.

See it in practice

Starting point

The share rose steadily every year from 20% to 35%, according to two observations ten years apart.

Using this skill

The share rose from 20% to 35% between the two recorded years.

Two endpoints do not establish what happened in every intervening year.

Writing practice

Practice table: electricity sources

Share of electricity generated in three regions:
North — renewable: 20% in 2010, 55% in 2025; other sources: 80%, 45%.
Central — renewable: 35% in 2010, 50% in 2025; other sources: 65%, 50%.
South — renewable: 10% in 2010, 40% in 2025; other sources: 90%, 60%.
Only these two years were measured. The table does not show total electricity output or individual fuels. The figures are invented for practice.

01 / Check your understanding

Try the skill

Choose an answer for each question. You can try again after reading the feedback.

1. Which overview is fully supported?
2. Which region had the largest increase in renewable share?

02 / Put it into words

Make it your own

Summarise the table in at least 150 words, selecting the main features and making comparisons. Aim for twenty minutes, then check every claim against the data.

Write at least 150 words. Use the checklist and example to review your work; this exercise does not give an automatic IELTS score.

Before you finish

  • My overview covers common growth and the change in ranking.
  • I selected figures to support meaningful comparisons.
  • I avoided claims about total output, individual fuels, or steady annual growth.

The table compares the shares of electricity generated from renewable and other sources in three regions in 2010 and 2025. Overall, renewables gained share in every region. North overtook Central to record the largest renewable proportion in the later year, while South retained the smallest share despite substantial growth.

In 2010, Central led with 35% of its electricity coming from renewable sources, compared with 20% in North and 10% in South. By 2025, North's figure had reached 55%, an increase of 35 percentage points and the largest gain recorded. Central's share rose more modestly, by fifteen points, to exactly half of its electricity generation.

South also experienced a sizeable shift, with its renewable share increasing by thirty percentage points to 40%. Other sources nevertheless remained dominant there, accounting for the remaining 60% in 2025. In contrast, these sources had become the smaller component in North, at 45%, while Central's electricity was divided equally between the two categories. The figures describe the composition of generation rather than the total amount produced.
