Don't be depressed. I'm sitting at 425 and i know that i'm gonna receive my ITA.
When you say that new IELTS scores are gonna come out, it's true. But remember that 2018 quota is gonna come out too and this means more ITAs and the score will go down.
You just have to keep faith. You are not alone in this journey and ROH is here to remember us that one day, sooner or later, we are all gonna live in Canada.
Be strong and positive
