Frequently asked questions

What is the difference between 'rose to' and 'rose by'?

'Rose to' gives the final figure (rose to 5 million). 'Rose by' gives the size of the change (rose by 3 million).

How many trend words should I use in Task 1?

Use enough variety to avoid repeating the same word, but accuracy matters more than quantity. Choose words that match the size of the change.

Should I describe every number on the graph?

No. Select the main trends and key figures, compare where relevant, and include a clear overview.

Is this vocabulary used in General Training Task 1?

No. General Training Task 1 is a letter. Trend vocabulary is for Academic Task 1 graphs and charts.
