around me people take those exams when they are going to study or work abroad or they are going to work in some overseas-funded enterprise and which require these certificates. they usually take the exams before they apply for the offer from the school or during they are applying the offer(some schools require they give GPA along with the grade they got from the exams).some of them find it hard to get the grades which the school or the company reqired might be willing to take the exams long before applying and take it for more than once.

Right, a band 8 score is quite difficult to get, but not impossible. If you'd like to visit my site: http://www.onlineconversationalist.com/ It has a little information on the different components and what examiners are looking for. I could also find some extra resources for you to practice with.

Hi I'm going to take IELTS exam whenever i believe myself to get overall 8 :))) so this means working hard and maybe never :D
