So I've decided on my schools and I submitted my application online (Southwark). After submitting I got the option to upload various docs (b cert, proof of address and some others). Am I supposed to do this or do I just wait until I've got a school and then provide relevant docs then? A bit confused b/c the Southwark Primary School Application pdf makes no mention of attaching supporting docs online and instead says you'll be required to provide originals and the woman I called at Southwark Council didn't seem to know anything about it.
