The way I see it, I dont have numbers for students who went there yearly from 2016-20. Students who went in -19,-20 are not causing a surge risk at this stage considering they are still in College and thus do not have points for canadian experience.
Students before 2016 would have made the PR by now. Students of 2016-2018 would have benefitted and most of them would now have scores between 475-500 (up from 445-470).
Cutoff would stay above 475 unless someone comes with a FSW (Foreign educated) magic wand
