please check my writing and correct my mistakes,then give a score

The first chart gives information about travel to and from the UK. The chart shows that between 1979 and 1999, there are most people that have visited out of UK by the UK residents rather than the people that have visited UK by overseas residents. In 1979 the visitors were about 10 millions people and after 1986 this process have increased significantly until 1999 and the biggest difference in amount of people that have visited the UK and UK residents that have visited abroad, related to the year of 1999.

I'm so sorry to say that your layout is so hard to review and your pattern should be improved to reach high score.
1. Introduction Paragraph (paraphrase the prompt)
2. Overall (trend of those charts)
3. First detail body paragraph (you can explain the line chart in dept)
4. Second detail body paragraph ( you can write detail information from bar chart)

* if you only have one graph you can write the differences in the first body paragraph and the similarities in the second body paragraph. good luck for your IELTS test.

Good advice by tiaDS. This is the approach I too suggest to everybody who prepare for this task. This approach would help you earn a good score at the exam while managing your time effectively for the task. You have to be mindful for both the score and the time management as this task has a major bearing on the time :)
