People are reducing scores to get OINP nomination and not applying as FSW.To be honest, I personally wouldn't reduce my score. First, I don't think it is worth the effort of figuring out what scores I need and manipulating my IELTS to score low. Second, this is a grey area with respect to misrepresentation. As of right now, people seem to think reducing scores on purpose is not misrepresentation. But IRCC gets horny rejecting FSW applications, and I simply don't want to give them a reason to do that to mine.
And I'd be very very uncomfortable using a supposed medical condition like this. But you get to make your own decision.
