This is awful advice. I got all 12s in my CELPIP because I prepared. I got CLB level 7 when I went to IELTS unprepared.
People here really need to stop asking if they think other random forumers think their score will magically increase because they screwed up their test. What would we know? You think you deserved better, but the examiners follow strict criteria and think otherwise. Your chances of getting a bump in score is very little.
If you score anything below 10 in CELPIP it means your English is not good and in my opinion, you will fail to get far ahead in a job in Canada. The idea of is this test isn't just to improve your CRS score, it's also a reflection of your chances to communicate and succeed in Canada and if you're not very good at English, you'll be driving Ubers instead of working in good management positions where excellent English is required.
I'm a PNP nominee working for a corporate company and can definitely say that people with poor English don't progress much unless they're some wizard coder and they don't need great English as they don't need to talk much at work.
So instead of complaining here, go study hard so you can achieve a better score.
Harsh advice but go deal with it.
