It would be worthwhile getting hold of a booklet called 'Choose a Wandsworth secondary school' from the town hall. This will list all the schools' distinct admission criteria, as well as the threshold distances for last year's successful applicants. It will also list the number of applicants for each school last year, as well as the number of appeals, and the appeals that succeeded. It is important to gauge whether you are likely to meet your preferred school's criteria. Too many parents spend ages agonising over the 'right' school for their child, only to find at the last minute they they would never have stood a chance of getting in anyway. Best of luck.
