I don't know your situation but I would like to ask you have you checked out all different avenues that can help you boost up your CRS ? Taking overseas education will definitely pay you but it will have it's own price of time and money both. My point is try figuring out if you can shoot up your score sitting in your home country, wouldn't that be more convenient ?
I 'll share what I 've done. My Crs was 435 with CLB 9 with ECA as bachelors. I 've re applied for ECA this time through ICAS since i did my masters in distance education from Sikkim manipal University. I am waiting for the ECA to arrive within next six months or so. If i get a positive ECA my score will take a quantum leap from 435 to 475. my IELTS expires in May 2020 so I've time till that. In case if that doesn't happen my last option would be going there for studies but again it's my perception . you may go ahead with whatever suits you. All the best.
