Ieey,
I feel your pain, i'm in the same boat, I only need a 7 and fail the reading every time, took it yesterday again for the 2nd time and I know ive already failed.
So far: speaking 8.5 Listening 8.5 Writing 7.5 reading 6.
Reading: The problem is the practice material by the IELTS in book and online form is not in the same format for the exam, it starts easy and works up to more difficult.
The first 8 questions yesterday was matching headings to 10 paragraphs, which completely through me. That's twice now its started with the same format. The practice material is not a true reflection of the exam, its way more harder, There are no mock papers that even relate to that and the amount is poor.
I'm losing the will to live.
