Hi OP
I know what an anxious time this is, two of my three kids have gone through the grammar process (middle child is at Newstead Wood).
But as a previous poster said - for this to be an option, you must have considered the school and had your DD sit the exam, even if you did not visit - weigh up that original opinion and what you based it on, vs a thread by someone who may have had a very unfortunate, but rare experience.
I am not taking away from the OP/ ex-student’s experience, it is awful if you are unhappy at school and it can cast a long shadow. But hundreds of girls go to that school and they all have their own lens, their own experience. My 3 children went to the same local primary, and if I only had the first child, I would have had quite a negative experience. But the next two have had a really happy positive time: dc1 was just unlucky, a combo of him, the class, a couple of his teachers, and it was not a great mix.
To get a broader ‘feel’ there are in fact quite a few threads on Newstead Wood on mumsnet: just type Newstead Wood into the search engine, and if you list by date, you can see the most recent first.
There are also a lot of personal opinions/ experiences listed on the eleven plus forum - I’ve attached the link below. There’s about 3 NW topics listed in the top section alone.

There’s also a couple of comments on NW here.

I hope that helps - and I know it’s easy for me to say, but don’t worry, most kids are happy whichever school the end up going to.
