This video identifies and explains three common mistakes students make when describing line graphs in IELTS writing task 1. The instructor uses a Cambridge IELTS 15 line graph example to illustrate these errors, focusing on improving comparison techniques, vocabulary, and detail management.
Mistake 1: Lack of Comparison: Students often only describe individual trends (increase, decrease, stability) without comparing the different lines on the graph. The video emphasizes the importance of comparing values and using comparative language ("more than," "bigger than").
Mistake 2: Limited Linking Words: Over-reliance on the word "then" is highlighted. The video encourages using a wider range of linking words such as "until," "before," "after," and phrases like "except for."
Mistake 3: Excessive Detail: Describing every minute fluctuation is unnecessary and can hurt the score. The video advocates grouping similar trends together and focusing on the main features, rather than providing a detailed account of every small change.
