I have a similar situation and applying for EOR from UAE. This was my third attempt and they have given me 6.5 again in writing. This time I was very confident in all my tests and scored an overall 8 despite this 6.5. Last time I had a similar situation and went for EOR which did not work. I think they intentionally do that to make money as they know 6.5 won’t work anywhere. I had also got my writing tasks corrected by various IELTS websites.
