My son is sitting a few pre-tests in year 7 (not 6) and I'm decidedly underwhelmed by the school's approach.
No one has been in touch with me to see which schools my son is sitting for (he's got one next Thursday!), I sent an email to the head year earlier this week saying "how do you manage the stream of boys sitting for pre-tests in addition to common entrance" (no reply). Today I talked with my son's form tutor after school and asked him the same, and he said: the CE prep will leave him in good stead for the pre-test, which is basically an 11+ with an extra page on the end.
Any thoughts?
