I was also being overtly optimistic and let multiple draws and a couple of months (April & May) pass by, before figuring out that waiting at 437 was not going to suffice at all. At 36 years of age, inching towards 37 i realized that I need to max out IELTS and get to 440+ given the uncertain nature of draws.
Registered and re-appeared for IELTS on the 25th of May and received results on June 6th. Revised score to 443 as per CLB 10 and was extremely hopeful, but as luck would have it, they skipped the draw.
I strongly believe that given the additional competition this year compared to previous years, all of us need to strive to max out our IELTS scores and for those of us who are 33+ explore every additional avenue to further complement our scores.
I am being optimistic again and hopeful that the CRS cut-off for the upcoming draw will range between 444 -447 this time around, even after a 3 week gap due to a slowdown in the influx of applicants with CRS of 440+.
Good luck to all of us for the 92nd draw on June 13th!!
