NO! You stand same chance if you have put it 1st or 6th
example
John has put school A first, but lives 3 miles away
Jane has put school A 2nd, but lives very close.
School gets sent list of all the names of all the kids regardless of 1st, 2nd etc.
School looks at kids plus criteria. Both Jack and Jane are eligible, they go on the schools list which is ordered according to criteria (siblings, looked after kids, faith kids, and then distance or whatever their criteria is.)
Jane goes at no.20 on the list and Jack as no. 300, because of distance. School has 170 places.
LEA gets school list back.
Jane could be offered a place at school A. LEA look at her form and find she prefers school Z. She can't be offered place at school Z, as she is too far away compared to others, so she is offered place at school A.
John cannot be offered place at school A as there are only 170 places and he is no. 300, he is no. 30 for his 2nd choice school so is offered that one.
It isn't first choices and then second choices, all the choices are all considered at the same time. Then if you qualify for more than one school (eg your first and fourth choices) the LEA looks at your form and sees which one you prefer. Offers you the place at first choice place and cancels the place at school no. four.
