Butterflies Believe it or not, but people are trying to help you here. it is fine, you don't have to give more information, but given that you appear worried, it may actually help you to provide a bit more information. In that way people with knowledge and experience could advise you in case you are about to make a serious mistake with your application.
If you, for example could list your local state schools: e.g.
School A, 2 miles, out of catchment, last year would have got in
School B, 0.1 mile, in catchment, last year would have got in but it is dire, special measures for 5 years
School C, 6 miles, out of catchment, last year would not have got in by 3 miles, outstanding
Then say I have put down C, F, G we would be able to give you more help.
