The numbers who sat the test used to be given on the admissions documentation but it hasn't been in recent years, in recent years they have also added a second day to allow for more to sit. Taken from the admissions document from a few years ago:

I would recommend avoiding sharing very high scores that might be your own, if you are above 220 you are fairly safe and it will only be unhelpful to others who haven't done so well to post high scores.

But then I know others who are not considering grammar as the independents have been reportedly so much better at coping with the pandemic and online learning so I think it is cutting both ways. For what it is worth Newstead have done a pretty good job during the pandemic with online and remote learning.

This year is unprecedented in all aspects. The admission criteria is created to be fair to most but unfortunately always the one who are in the middle suffers mostly. Because they won’t fit in any box.
We have the results now, and we have just to wait till 1st of March

Thank you! I hope so...

The chances are, she will get in by at least 7 marks difference from the cut-off mark.
