It makes me smile that admissions paranoia stretches now to dissing the tutor you have chosen for your child. Let's not discuss necessarily but just reflect on such approval seeking anxieties and what that does to the children of such parents.
Oooh, no - let's discuss it!
Hey, there are some awful tutors out there just in it to make money, with no real worries about how able a child is to cope with the work - they'll happily pander to the "get my child through at all costs" parent, who will likewise slag the tutor off when their none-too-bright child fails to get a place.
And then there are some really good tutors out there, who will tell the parents if they have suspicions that the child is weak or very weak in one or more areas of the curriculum, and will also say if there's no real chance of either passing the exam or coping at the school if they do pass.
There are some tutors who give just the right level of tutoring to get a child familiar with the question types & exam, yet still have fun with the exam.
