We have seen the likes of
@ZAtoCD with 481. All it takes is to be under 30, have a masters degree, max out your IELTS and have your 3years of work experience. This has been doable for many in recent times, not to mention that the level of awareness for Canadian Immigration has improved significantly as well.
