In fairness, how many years ago was this?
I live in a grammar school area (although my little ones are pre schoolers so not relevant to me at the moment) & I would say 99% of the people who want to do the 11+ are tutored from year 4. In fact I know of only 1 person who didnt.
And then its a vicious circle, they take the top 100 scores so if everyone else is tutoring then you better had too!
I vehemently disagree with tutoring as it effectively prices out bright but low income kids & like someone said above it then basically becomes like ‘free’ private education
The comps round here are a disgrace so competition for a grammar place is fierce (I went to a comp that went into special measures, became an academy & then shut due to lack of improvement so speaking from experience)
On the other hand Im a massive hypocrite because when my kids come to that age, will I tutor them to
pass the 11+? Yeah I definitely will
(But would only put them in for it if they are sufficiently academic to cope at a grammar school)
