Hi - don't like to see you talking to yourself !! Not sure if I know that much though
there are various reasons why lists can go on moving right up until the kids start the term (longer sometimes)
Some people accept and pay the deposit for an indie but have financial concerns that make them wary of immediately giving up the state school place they have been offered. Hence there are occasions when kids simply do not turn up on day 1 of the autumn term.
Some people end up moving house - the news that they have to comes after the allocations. - hence a place appears.
?? sure there might be more
