The Challenge: Two Charts, Twenty Minutes, One Confusing Task

Picture this: you open your IELTS Writing Task 1 paper and instead of one familiar chart, you’re staring at two different visual representations—perhaps a bar chart showing tourist numbers alongside a line graph displaying satisfaction ratings. Your heart sinks. How do you tackle both? Which should you describe first? And how do you connect them without writing 300 words?

Mixed chart tasks are increasingly common in IELTS Academic Writing Task 1, and they separate Band 6 candidates from Band 7+ achievers. This comprehensive guide will show you exactly how to analyse multiple data sources, organise your response, and write a coherent report that impresses examiners.

Quick Answer: How to Approach Mixed Charts

Spend 3-4 minutes analysing both charts together, identify the relationship between them, group similar trends, and write four paragraphs: introduction (paraphrase), overview (main trends across both charts), body paragraph 1 (key features from chart 1), and body paragraph 2 (key features from chart 2 + connections). Keep your response between 150-180 words and always show how the data sources relate to each other.

Why Mixed Charts Matter for Your Band Score

Mixed chart tasks test advanced skills that single-chart questions cannot assess. Examiners want to see whether you can:

• Synthesise information from multiple sources—a crucial academic skill
• Identify correlations and relationships between different data sets
• Prioritise effectively when faced with abundant information
• Maintain coherence whilst shifting between different visual formats

Candidates who treat mixed charts as two separate tasks typically score Band 6.0. Those who integrate the analysis and show connections achieve Band 7.0 and above. The difference lies in your approach, not your English level.

Step-by-Step Strategy for Mixed Chart Success

Step 1: Analyse the Relationship (3 minutes)

Before writing a single word, ask yourself:

• What connects these two charts? (Time period? Subject matter? Location?)
• Do they show the same trends or contrasting patterns?
• Does one chart explain the other?

Look for cause-and-effect relationships, correlations, or time-based progressions. Write these connections in the margin—they will form the backbone of your overview.

Step 2: Identify Key Features (2 minutes)

For each chart, note:

• Highest and lowest values
• Significant changes (peaks, troughs, sudden shifts)
• Starting and ending points
• Any unusual patterns or exceptions

Step 3: Plan Your Paragraphs (2 minutes)

Paragraph structure:

1. Introduction: Paraphrase the question, mention both charts
2. Overview: 2-3 main trends spanning BOTH charts (most important paragraph)
3. Body Paragraph 1: Detailed analysis of Chart 1
4. Body Paragraph 2: Detailed analysis of Chart 2 + connections to Chart 1

Step 4: Write Strategically (12 minutes)

Follow your plan. Use linking phrases to connect ideas: “Similarly,” “In contrast,” “This trend is reflected in,” “Consequently.”

Step 5: Review (1 minute)

Check word count, grammar, and that you’ve mentioned both charts in the overview.

Model Answer: Mixed Charts Task

Task: The bar chart shows international tourist arrivals in Australia (millions) from 2010 to 2020. The line graph shows average tourist spending per visit (Australian dollars) during the same period.

The bar chart illustrates the number of international tourists visiting Australia annually between 2010 and 2020, whilst the line graph indicates how much each visitor spent on average during the same period.

Overall, tourist arrivals grew substantially throughout most of the decade despite a dramatic drop in 2020. Interestingly, this increase in visitor numbers coincided with a steady rise in individual spending, suggesting that Australia became both more popular and more expensive for tourists over time.

In 2010, Australia received approximately 5.8 million international visitors. This figure rose gradually to 8.2 million by 2018, representing a 41% increase. However, numbers plummeted to merely 1.8 million in 2020, the lowest point in the entire period.

Average spending per tourist followed a similar upward trajectory, climbing from $3,400 in 2010 to $5,200 by 2019. Whilst visitor numbers peaked in 2018, individual expenditure continued rising for an additional year before both metrics fell sharply in 2020, presumably due to global travel restrictions.

Common Mistakes to Avoid

Mistake 1: Describing Charts Separately

❌ Poor: “The bar chart shows tourist numbers increased. The line graph shows spending also increased.”

✅ Better: “The bar chart shows tourist numbers increased, a trend mirrored in the line graph’s rising spending figures.”

Mistake 2: Missing the Overview

Examiners penalise responses without a clear overview. Always summarise the main trends across both charts.

Mistake 3: Including Every Data Point

Select key figures only. You have 20 minutes and 150+ words—be selective.

Mistake 4: Using the Same Vocabulary

Variety matters. Use synonyms: increased, rose, climbed, grew, surged, skyrocketed.

Mistake 5: No Conclusion

Task 1 requires no conclusion—end with your final body paragraph.

Pro Tips for Band 7+

Tip 1: Master Comparison Language

Use sophisticated connectors:

• Correspondingly, Likewise, In parallel (similar trends)
• Conversely, By contrast, Whereas (different trends)
• This pattern is reflected in, mirroring the trend seen in (connections)

Tip 2: Practise with Real Tests

Cambridge IELTS books 15-19 contain excellent mixed chart examples. Time yourself strictly.

Tip 3: Learn Chart-Specific Vocabulary

For more guidance on describing individual chart types, see our dedicated guides on line graphs, bar charts, and pie charts.

Tip 4: Check Your Grammar Range

Mixed charts require complex structures:

• While/Whereas clauses: “Whilst visitor numbers peaked in 2018, spending continued rising.”
• Participle clauses: “Having increased steadily for years, both figures dropped sharply.”
• Comparative structures: “The growth in arrivals was considerably more dramatic than the rise in spending.”

Tip 5: Manage Your Time Ruthlessly

Analyse both charts	3-4 minutes
Plan and note key features	2-3 minutes
Write response	12 minutes
Review	1 minute

Frequently Asked Questions

Do I need to write equal amounts about each chart?

Not necessarily. If one chart shows more significant changes, spend more time on it. However, you must mention both in your overview and provide specific data from each.

What if I can’t see a connection between the charts?

There is always a connection—often temporal (same time period) or thematic (same subject). If trends differ, emphasise this contrast in your overview.

Should I use different paragraphs for each chart?

Generally yes—one body paragraph per chart works best. But always reference connections between them rather than treating them in isolation.

How do I improve my vocabulary for Task 1?

Study our collocations guide and essential vocabulary lists to expand your academic language range.

Can I get Band 9 with mixed charts?

Absolutely. The key is sophisticated analysis, precise vocabulary, grammatical accuracy, and clear organisation—all demonstrated in our model answer above.

Take Your Task 1 Skills Further

Mixed charts may seem intimidating, but with the right strategy, they become an opportunity to demonstrate advanced analytical skills. Remember: the examiner wants to see connections, not just descriptions.
