Total Places (A) = 695 Potential No of Candidates (B) = 3500 A/B 20% possibly 1/5 places awarded.
Can this be a valid and simplistic way of looking at the possibility of success of a child getting into the above schols.?
Not sure quite where you're going with this Pi? and I'm still trying to understand KenR's responce! - I'll get there eventually
You might like to lower the "Potential No of Candidates" figure though. The few heads of Grammars and independant schools that I've talked to gave a pretty consistent story of perhaps 1/6-to-1/5 of applicants not really being in any way credible potential candidates to enter the school.
Also not all KEVI places offered are accepted - in responce the schools 'overbook' by (IIRC) a similar amount.
So, if you're sure your child is at least a credible candidate and you would
accept the place then you 'chances' improve dramatically - FWIW?
