Still undecided! What school did you chose in the end? Are you happy with the choice you made?
Yes, the grammar school would be Bourne - and would require a move.
We were out of catchment for Bourne and Spalding, but chose Spalding as this is where our son said he wanted to go when he asked if he could sit the 11+. We were lucky and he passed really well and got into Spalding. I think as Alex said you have to decide which is best suited to the type of person your son is. Obvioulsy the academic side is of importance, but with the fact that the schools both have things to offer, other facts must oalso be considered.
We chose Spalding over Bourne as that is where we thought he would be more suited.
Let me know what you decide.
