With a HA5 postcode I think only Bucks school you are likely to gain admission to is Chesham Gram. Look at Bucks 11+ forum Sally Anne is a wealth of info. Be careful not to waste choices if you have no chance of admission.
Thank you, decaff!
I agree that Chesham GS is the only Bucks GS you have a realistic chance of gaining a place at. There are lots of kids from Harrow there because the Met Line runs direct to Chesham. Be aware, though, that the school is becoming more popular every year, and recently received an Outstanding report from OFSTED. This year the school was oversubscribed on 1st March, for the first time in living memory. It did go to "All Offered" eventually.
This triggers me another question - Do we need to put that non-grammar high school (nearby) in CAF ? If we dont get into any of the 6 preferred schools in CAF, wouldnt that nearby school be allotted by default ?
You need to find out whether the school is regularly oversubscribed. If it is, you must
put it on your CAF in 6th place.
You can only use the strategy of leaving the likely "default" school off the CAF if you are absolutely 100% certain that you will get in. Otherwise, everyone who has put the school on the CAF will be in the queue ahead of you, while you could be allocated a sink school miles away.
