I am trying to find out how many opted for 1st preference for RGS.
I have the numbers somewhere, but as others have said, the number of first preferences simply isn't relevant. The school is popular, but not ridiculously so.
If I am not residing in catchment area (currently i am in sunderland - north east) and planning to move later this year to high wycombe then what will be realistic chance to get into RGS.
If you move before the deadline for proof of address, and you are living no more than 5 miles from the school, your chances are very good. Please look at the link that mitasol posted for evidence of that.
I am assuming this needs to go above score 121 and there is no other seperate test for RGS or any other GS in Bucks area.
