I believe practice is the key. Just focus on giving your best. Practice as many tests as you can. Watch english movies and read books and newspapers, it will add to your vocabulary. I did not score full though, my score was
R:8.5
L:8.5
S:8
W:7
But i put my best effort for 10 days. All i did was practice tests for 10 days.
Just watch IELTS practice videos on youtube , i did same thing for 10 days straight and my IELTS results got much better in no time:
S:8.5 L:9 R:7.5 w:7.5
In addition to your further, focused practice, I recommend these 2 sites to help you get more resources; http://ieltsliz.com/ and http://www.ieltsbuddy.com/
