I am AOR May 6, 2019 (file still processing in Montreal VO
) but I'll give my 2 cents about improving your CRS score. I know it seems trivial but hear me out: give it a try with French!
Back in April/May, the cut-off was still relatively low (450s) and my CRS was 453. However, I wanted to do everything in my power to increase my CRS and have better odds to receive the ITA. I went ahead and scheduled the TEF CANADA.
My CRS went up from 453 to 498 points (45 point increase) just because of French. So for those who exhausted all other options, I recommend signing up for an intensive French course.
My score increased by 45 points because I scored C1, which is advanced but I'm sure that B1/B2 level (which is totally achievable after 1-2 years of study) will get you places.
I KNOW, it might be expensive. I KNOW it's an investment for 1-2 years from now. But I see a lot of stories where people went extra length to get better CRS, so why not learn French? It will also give you better odds to find a job in Canada, since bilingualism is very well seen.
