Where do I even start? It's such a daunting task! Eeek!
We know we want to live fairly close to central London (zone 2/3), but what about schools? Should I use those as a criteria? Oldest dc is 2.5y- what if the school ratings have changed by the time he gets to secondary age? And should we choose to live closer to a grammar school and hope they're bright enough to get in (and hope grammar schools are still in operation)!
