The 4-step method
Step 1 — Paraphrase the prompt in one sentence. Your opening sentence should name the time period, the metric, and the number of lines, without copying the wording of the question.
Step 2 — Give the overall trend in 1–2 sentences. State the general direction (rising, falling, fluctuating) and the most striking contrast. This overview is worth roughly 25% of the Task Achievement score.
Step 3 — Group similar lines and describe 2–3 clusters. Avoid describing each line separately. Group them by behaviour: 'the rapidly rising economies', 'the late starters', 'the steady performers'. Reference specific figures for the highest, lowest, and turning points only.
Step 4 — Close with a notable anomaly or comparison. End on something memorable: a crossover, a sudden surge, or the gap between the leader and the laggard.

The line graph shows the percentage of households with internet access in four countries between 2000 and 2020. Overall, internet access rose in every country, but the rate of growth varied substantially. South Korea started from the highest base and reached saturation well before the others, while the United States and Japan followed similar upward trajectories, and Brazil lagged behind throughout. In 2000, South Korea already had the highest penetration rate, at roughly 45 percent, while the figure for Brazil stood at just under 5 percent. Over the following two decades, South Korea's rate climbed steadily, exceeding 95 percent by 2015 and remaining close to that level thereafter. The United States and Japan both started the period at around 25 percent and grew at comparable paces, although Japan overtook the United States briefly between 2005 and 2010 before the two converged again at approximately 90 percent by 2020. Brazil experienced the most dramatic change. From less than 5 percent in 2000, household internet access grew rapidly after 2008, reaching about 80 percent by the end of the period — a sixteen-fold increase that nevertheless left Brazil marginally behind the other three countries.

Frequently Asked Questions
How do I structure a line graph Task 1 answer?▾
Open with a one-sentence paraphrase that names the time period, the metric, and the number of lines. Then describe the overall trend, group lines by similarity, highlight the highest and lowest points, and finish with any notable crossover or anomaly.
Do I need to mention every data point?▾
No. Listing every number is a Band 6 mistake. Instead, group data into trend clusters (e.g. 'rose sharply between 2005 and 2008', 'plateaued in the middle years') and reference specific figures only for the highest, lowest, and turning points.
What's the biggest band-7 vocabulary mistake on line graphs?▾
Repeating 'increased', 'decreased', and 'went up'. Use precise alternatives: 'surged', 'plummeted', 'plateaued', 'fluctuated', 'peaked at', 'tapered off', 'doubled', 'tripled' — and pair them with accurate adverbs ('slightly', 'dramatically', 'steadily').
How long should my line graph answer be?▾
Aim for 170–190 words. Going significantly over the recommended word count usually means you are describing rather than summarising, which costs you the Task Achievement band.
