Now, to answer your questions, based on what I assume would most likely be the case for St Paul's:
Could any current parents give some insight into the school - Do parents have a similar reputation for being too competitive at the expense of the boys well being?
Probably some pushy and competitive parents. But most will be super-rich so that their sons will be employed in the family business anyway regardless of grades. The hyper pushy middle-class types will be mostly gone, priced out by the astronomical fees.
If you have a boy there do you still use tutors if so why and if not is it something you feel you should do?
I don't really know in the particular case of St Paul's, but as a tutor myself I have often tutored students who attend similar expensive private schools. Most of these schools used to provide after-school tuition and catch-up classes for those who needed them. This increasingly is no longer the case as most of these schools have deteriorated in quality while at the same time becoming ever more expensive. So you may need to hire an after-school tutor if your son falls behind.
Also, I've heard the boys get lots of homework- does that mean that they don't have time for extra curricular weekday clubs outside of school?
Possibly you will get more homework than in other schools, but there is no reason why this should be the case as I assume St Paul's follows the same academic syllabus as most other schools.
Would like some info as my son will start Yr7 in Sept and coming from state school. We have never used a tutor as we couldn't afford it and are not likely to in the future - Will he fall behind those being tutored?
That will depend on his academic ability. If he is academically able and hardworking, it is unlikely he will need tutoring. Tutoring, in my experience, is only useful for slow learners who want to get from an E or F grade to a C or D grade. It's usually of no help to academically able students, maybe even counterproductive as they won't learn to study independently.
He does extra curricular sport and music after school - would the homework be too much for him to continue these in Yr7.
In general, assuming St Paul's follows the normal syllabus at KS3, if he is diligent and disciplined about doing his work when it is set, then he should have plenty of time left over for sports and music. At my school, we had a long day with free study periods that we used to do our homework. I'm assuming St Paul's is similar, maybe I'm wrong.
And BTW, I'm assuming your son is starting at St Paul's Juniors (AKA Colet Court) as I think St Paul's proper only starts at 13+. Do correct me if I'm wrong.
Would really like to hear parents views on bullying as well - and generally how they have managed friendships especially if they came from a state school. Thanks
If your son follows the golden rule of keeping to himself unless spoken to, then he should be okay. Of course, I'm speaking as a general rule here, and I'm assuming this would apply to St Paul's. I wouldn't expect the state-private "culture shock" to be much of an issue as long as your son is hard-working, well-behaved, and polite. I went from an inner London comprehensive on to a top university, where many kids had gone to private schools. There was no culture shock as we all just got along and studied hard.
