my husband had the same problem, he finally got 7`s on his 3rd attempt, I goggled ielts writing ect ( & ielts scoring ) & downloaded paper after paper for him and we practised together every night, then went through them with a fine tooth comb, my advice is to do exactly what it says on the paper in the exact order, some people were on their 7/8th attempt, keep practising, keep trying you will get there in the end, good luck
