hi, I sat my ielts three weeks ago and got my results last Friday, I was extremely nervous and was most worried about writing as I can never put down on paper what I mean. i had a complete mind block in the speaking and actually went completely silent for about twenty seconds and also though afterwards how much more i could have said. i ran out of the time on my writing test without finishing and was certain i would fail (needed minimums of 7's. but i got a 9 on speaking which i couldn't believe, and got a 7 on my writing, 7.5 on reading and 9 on listening. so basically don't panic over it because i did and was ok as i am sure you will be. good luck
