We're Kent too - have one DS in reception at our second choice school, so have applied to our first choice again for DD, and hoping she gets in so the sibling rule kicks in and we can move DS.
The waiting is killing me!! I had to apply by post this year as the reason we got second choice last year is because I failed to tick one box in our application, so I wanted to get the school to physically check my form this year. But it does mean waiting until the 1st, rather than being able to log on at 4pm on the 31st March.
Fingers crossed everyone!
