Interestingly, the report we discussed is actually one of the sample answers from the back of the official Cambridge IELTS 15 book. Next time you're practicing at home, don't forget to review the sample and model answers included at the end of the book.

Here is the examiner's comment:
This is a full and detailed description of the data contained in the graph, supplemented by a comparison of the variations in the numbers for the two types of visitors (staying on cruise ships or staying on the island). There is a clear overview at the end of the description. Organisation is fairly clear and progresses logically across the time period, although it could be improved by subdividing the rather long second paragraph. The range of vocabulary is wide enough to show some variety of expression [adds up to | totals up to] and some use of collocation [three ... years in a row]. There is a high level of accuracy in grammatical control, in both simple and complex structures, but there is an omission of a full stop between the first and second sentences and no capital letter to indicate the beginning of the new sentence.
