ia want to take IELTS test. how should i prepare for it to get at least 8 out of 10???

First it is not out of 10 Each section is scored at a scale of 9 bands. U can take coaching from any coaching institute for a month to get agud score. For most of master programs u need 7 bands.

Vikas - though IELTS is not a very difficult test, getting 8 out of 9 is not a easy task. Ideally, check your current level of English using mock tests that are available. When you register for IELTS at the British Council you also can access the online resources free - these are usually the closest

No 10. The maximum is only 9. there are many british council recognised IELTS coashin centers. Take good coachig and then write youc an get even 9 out of 9
