The CRS might come down to 430 by the time you retake IELTS and get your scores, but if you have time, go for it.
I'll say that focusing hard on studying French, as well as getting moral support from the good people here, are helping me. I am in a much worse situation, 410 and going down to 399 in February, so I really need a provincial nomination but missed the July 25 deadline to apply for OINP by one day. This wait for OINP to reopen the HCP stream has been really hard on me and wearing me out a lot lately. In times like these, I need moral support as well as something interesting to consume my mind that would also help me with my goal, and that's what I'm doing with French study for now.
