Ideally want to send my DD to St. Paul's girls or otherwise another London girls independent school - but apart from registering with the obvious feeder schools, how many additional schools do people usually register with to be "sure" that you'll get at least one primary spot? I can't risk not getting a primary school spot even if it's not with one of our preferred schools but at the same time can't spend a fortune on registration fees. I'm not from the UK so the system is totally confusing!
