It's joke for BC people. I think they unintentionally score 0.5 less in writing or speaking, so that they can earn revenues from additional tests. In such scenarios only few people almost 10% or even less are scored more than 7.You are absolutely right. I sat for IELTS twice within one and a half month and my scores are following:
LRWS: 8.5 9 7.5 6.5 (30th September, Ottawa, BC)
LRWS: 9 8.5 6.5 7 (11th November, Dhaka, BC)
Is this a joke or what?
I have also observed less deserving people going ahead in this race just because of sheer luck.
Try for reval. All the best!
