At my daughter school year 6 there are now 3 extra after school sessions , maths (level 6). English ( level 6) reading( level 6). I picked up my daughter from her after school clubs, and watched the kids come out who attended these sessions.
(About 15 in each class) every single one apart from 2 had / are being tutored and went in for the 11+ (4 got in)
So not really g & t. Just tutored.
I know this probably only applies to my DDS school, but it seems that the other kids who need extra help don't get it
