Try again! doesn't matter how many times but if your dream is to be a Canadian citizen then you gotta try again. write down 100 essays, 100 letters to get mastered, keep trying. I am sure you already know inside-outside of IELTS mechanism, just keep practicing. Study and practice. Make it clb 9. there is no other better ways then having CRS score more than 400. You can try getting nomination from different PNPs but in my opinion they are hard to secure. However you will qualify for OINP if you can get over 400 and again for that you need CLB 9!Even after multiple attempts my score is not changing L-8 R-8 S-7 W-6.5, CRS score - 371, can you tell me now how I can look for immigration ?
Good Luck!
