Optimism is what kept me going for the past two years now. I started this process in July 2017 and entered the pool for the first time in October 2017 with a CRS of 432, seeing cutoffs till 433 after I entered. Many said that cutoffs will drop to 432 and I will get it but it never happened. If I would've changed my profile to spouse not accompanying that time, it would've been 437 and a direct ITA would've been received(But I wasn't aware that we can do this way and many were saying its misinterpretation). After that, scores have been way high!
I'm still hopeful to see Canada one day!
