It seems every year the 11+ becomes more manic people seem to go to more desperate to get in to grammar schools. The reasons for this are obvious in that they are not enough grammar schools to go around. The result is a 'annual' bout of madness occurs between now and when the results come out 'different ' times in the various selective areas.
The reason sixth form entry is easier is because at least everybody knows what is required for admission to the school concerned. Admittedly requirements vary massively within grammar schools, but at least 'bright' kids who work hard have got a chance should they so wish.
The entry to sixth form is so much more 'democratic' and based on ability rather than two or three random tests on any day. It must make it easier and more fair for non 'trained' kids because they are not working against some 'secret' and unusual admission exams.
I am relieved its over for me having had three go though it and having possibly the 'brightest' one fail it. I still have the difficulty of finding a 'selective' place for DS ( be that private or grammar) who will be year 10 when I move next year.
