AIBU to remind parents in England (&Wales?) of children who will turn 5 between 1st Sept 2018 and 31st Aug 2019 that today is the deadline for submitting your application?
If you have forgotten do it now.
If you aren't sure whether you pressed submit then check!
If you only put down one school then are you really sure you will get in?
Have you put them in your true order of preference?
Have you got a 'banker' school on your form somewhere?
