Bubble - hope it comes today. Will be thinking of you :)
Tamtam2 - I think we were there for a couple of hours, but maybe only 45 minutes of that was us in our appeal. We waited a while at the beginning while the panel got ready, and then the four families who were appealing for that school that afternoon (there were 40 appeals for this school, so they held a number of days of meetings) went in together to hear the school's case. We were invited to ask questions after that, and there were quite a few questions about the admissions process that had led to so many appeals. After that, the other 3 families left as we were timetabled to go first, and we put forward our case. The panel asked us questions, but I never felt that they were trying to catch us out. They were really kind and gentle and asked us questions which brought out our situation and the real issues for us.
The school were there (they came in with us) and actually they were great too. There was a very funny moment when we had to check the maps to look at the distance. We live 20 miles from the school and they only had a local map, so they got out the local map and then drew a long line down the table to show us where we lived in relation to others. We couldn't help laughing because it all seemed so ridiculous. The school were supportive of our case, which had arisen because of a change in admissions procedures which were subsequently reversed...
Afterwards we came out with the school and DH burst into tears to be consoled by the headteacher... It was all quite bizarre. We had to wait a week to hear because there were so many appeals, but the headteacher called us on the Friday night and we had a letter from the panel to confirm DD2's place the following day.
Try to relax and not to panic. It is hard but our panel was really good and they worked hard to put us at ease so that we could make the best of the opportunity.
Do ask for help on here - there are lots of people with experience of appeals and some admissions experts who will help you all they can :)
