What to confirm before writing
Mark the overall rise or fall, highest and lowest points, turning points, crossovers, and scale gaps, then choose two headline trends.
Turn the chart type into an overview, data selection, comparisons, and sentence control first. The goal is not memorising one sample; it is knowing what this chart needs most.
Decide which relationship the chart requires first, then choose the figures and language that support the overview.
Reporting every year in order, or writing only that changes occurred in the overview, weakens both the summary and data selection.
Check whether the overview states the main direction, largest turning point, crossover, or scale; omitting the chart’s clearest feature is the first rewrite signal.
Mark the overall rise or fall, highest and lowest points, turning points, crossovers, and scale gaps, then choose two headline trends.
Rewrite the overview without detailed figures, then keep only data that proves those two headline trends in the body.
First check direction: which lines rise, fall, or remain stable overall. Second, turning points: which line changes direction. Third, crossovers: when rankings switch. Fourth, scale: whether the highest and lowest are far apart. The overview need not include all four; choose the two that best summarise the chart. Missing the clearest crossover or reversal usually means the summary is still incomplete.
If the overview says A rose steadily and overtook B, the body needs A’s start, crossover, and end plus the matching B values; every intervening year is unnecessary. Write the overview judgement first, then choose two or three pieces of evidence for each claim. This produces clearer groups than copying figures from left to right.

After submitting a Task 1 report, inspect the overview, key data, comparisons, and sentence accuracy first, then decide whether to rewrite the overview, data sentences, or linking.
