Re: Ielts
I agree, its exam technique, parts of it are not too different from O'level English language as it was in the late 90's. There are courses in the UK and else where which will teach you to pass, even with a relatively poor grasp of English
As mentioned above there are tricks to passing the writing section in particular and just a bit of practice and perhaps doing a couple of tasks by explaining to a friend and discussing the task will help.
