Did you pass the tests in one and the same town/center? If not I'd suggest to try in some other town. Writing and listening sections are very subjective and really depend on the examinator. The discrepancy is too big I'd say - having 8 8 8 and 6.5. For example, I know that there are some IELTS centers (which mostly involve the same examinators each time) which often gave the writing results way lower than the other ones. And those people who decided to pass the exam in another town got the points they wanted. So..robinbharg said:Its really disappointing to see 8 in 3 sections and 6.5 in writing. Really bad as it kicks you out of the league for 0.5 points
Just sharing some info I have, don't know is that applicable in your case
