Hi everyone,
I registered around 2 hours ago I watched all speaking videos. Actually, I have some questions about those. Which one is the best video and the worst? Why?

Hi Ceyda,
You asked which one is the best video and the worst and why?
As you know there is no pass mark for IELTS, only bands awarded. You have told us you want to get a 7 which is a ‘Good User’ according to IELTS.
If you have a look here: http://www.ielts.org/institutions/test_format_and_results.aspx at Q5 you will see that you are graded on your performance and that each band corresponds to a level of English competence.
For example a Band 7 ‘performance’ is someone who has ‘operational command of the language, though with occasional inaccuracies, inappropriacies and misunderstandings in some situations. Generally handles complex language well and understands detailed reasoning’
I think if you watch the videos again with these Bands in mind you will see the difference between each of the ‘candidates’ performances. Clearly some are better than others.
We are offering these videos as an opportunity for students/potential candidates to see and judge for themselves which performance they would compare themselves to and/or aspire to by way of improvement.
