Well difficult really - phone lines to indies can be bit hot in the first week of March.... however they won't know now if they are going to have places
If you try phoning now - best to ask about admission in September - say you are considering their school as heard it was good for languages or whatever and you think it may suit your DD better than the local state schools - don't say you don't think you'll get your choices at the state schools!!!
They may well invite you to look round (and will try and get more info out of you) - the visits are generally very nice (they are keen to get people) and very interesting. I went to a school when DS was in year 4 - thought I might be moving to the area, were there 2 hours - very nice individual tour , tea and cakes - lot of input considering we were so far off applying at that time.
If they offer a visit - go.
