When writing Task 2 essays, introducing examples is important and helpful. Examples strengthen your analyses and make them more practical.
However, the challenge is that we may be unable to remember statistics or case studies that we read in the past. The solution is to invent examples, or in other words, to make them up. IELTS examiners do not have time to check the validity of your examples on Google!
Three ways to introduce examples in Writing Task 2 essays are:
1. Using examples with specific statistics
2. Using examples without specific statistics
3. Using social trends
