Ursuline high & St Mary's

[SRose]

I heard a rumour that if your DD attend St Mar's primary school in South Wimbledon, it would be an advantage to get into Ursuline high school. Does anyone know if it's true?
Our DD's starting reception at All saints soon( in year admission) and put her name on the waiting list of St Mary's (within catchment&regular mass attendance).
As we are Catholic and SM is our 1st choice but we are thinking to stay at All Saints if DD likes it.
Then I heard this rumour...If this is true, we will keep renewing the waiting list.
Anyone knows anything about it????

Thank you!!

SRose think that is just a rumour - who have you heard this from? St Mary's will unofficially be a feeder school for Ursuline High (for girls) by dint of being the most local Catholic primary school but I can see nothing in their current Admissions Policy to suggest that children are advantaged by the primary school they attend?
