I am on the same boat as you ..max upto 459 if I can get 7.5 in writing...I got 9,8.5, 8 and 7 last time. You don't need 9 in all to get the extra 3 points, just 9, 8.5, 8 and 7.5 will do.Currently at 456 and losing hope; just registered for IELTS again, I can go up to 459 if I max out (L9, W9, S9, R9)
Wish me luck, guys.
