I don't have any hat in the ring now, but I did in 2019/2020. Y6 at a state primary where remote learning was, well, too remote to even see it.
I definitely didn't have the money for tutoring and was too unwell with chemo myself to help her in any meaningful way. But, what I did do was print of sample papers from Emanuel, SCHS, Manchester Grammar School, Alleyn's and a couple of others I forget. This was solely to get her used to exam conditions.
ISEB wasn't in play for the one (GDST) school that we applied to, so it was written Maths and English papers only.
She applied for a drama scholarship (didn't get it) and a bursary (got one). She is dyslexic and CAT4 was around 112 in Y4.
Hours wise - hmm not loads, I guess around 20-30 mins a day with bond books for maths, and an hour on top for exam time practise most weekends from September to January of Y6 (exam day was 1st week in Jan). Interview was around November time iirc and consisted of groups of 3/4 girls with an SLT and was a chat about a painting - what did they think the artist was aiming for, what did they think the subject was thinking sort of thing, any sports and hobbies etc. about 30 mins.
She is NOT the smartest in her year by a long shot, but she is engaging and works hard. Expected GCSE grades between 6 and 9 for eg.
Is now a county player in her chosen sport, but was not at that level aged 10/11.
Offer received on offers day.
I don't doubt that things are definitely more difficult even a couple or 3 years on, which I find so sad for the children, but I wouldn't do anything differently I don't think. My feelings were and are, that if I'd had to heavily tutor her for a place, then perhaps that school wasn't for her as I simply wouldn't have had the funds to support ongoing tutoring.
I appreciate how very very fortunate she is to have her bursary, but I am also realising that she has not found her stride academically until now, in Y9, which is why this all seems so hard to read that some children are being put through so much. Hey, they might enjoy it, and that's fine, but I just wonder if the collective parents of SW London have created a self perpetuating steam train of tutoring that can't stop.
I know parents whose children were tutored heavily for 11+ and are still tutored now - I can't see how this is good. My DD does around 12 hours of external sport each week, which she loves, and generally has an hour-90 mins of h/work a day max and even that isn't a constant. Sometimes it's much less, occasionally more.
I don't even know what my point is really! Other than we don't all embark on this in the same way. If someone wants to say their child has 1-2 hrs of tutoring time per day, that's their lookout, but that does NOT mean everyone does this and also does not mean that those of us who do far far less are lying.
I wish all of your children the very best of luck for offer day, there is a place for everyone eventually (though I know the fear!), and as clichéd as it is, the right school for the right child really is a thing.
