in terms of worst advice, could add those people (Parents?!) who state blithely that if children are bright enough they will get into grammar with no additional work/preparation, and if they can't then they shouldn't be there. That infuriates me. Probably a different discussion though!
I agree, that's lamb to the slaughter territory.
Equally bad though is the advice that it's essential to hire a tutor, particularly if it's presented as a barrier to entry. Firstly, it isn't essential if the parents are competent and willing enough to make the effort instead. Secondly, it must be hard to know which one to choose and how to tell whether a tutor is really worth their salt. Thirdly, without parental involvement there's only so much even a good tutor can accomplish.
This is hotting up! Totally agree with all of you - the non support of the state school, the idea that "if a child is bright enough... ( boy, I heard that many times! ) and also agree about tutoring - It can be done DIY, but of course most of us parents are juggling time and "outsourcing" is the answer. But if one is earning £50 or more an hour and a tuition cost £25 an hour, it makes sense, provided of course the quality is there. Although I mainly did DIY, I was given a good advice from a parent, whose child did spectacularly well in the previous year, that my DS will / could benefit from the "group learning" ( peer pressure?!
) environment, and that was a great advice. DS definitely got the idea of how well the others were preparing. He also made good friends and always hear them sizing each other, in a friendly way, i.e who got the highest mark in today's test, homework, quiz etc. which DS really enjoyed.
