He doesn't teach year 7 and 8 though
he teaches older ones.
They have entry at 11 and 13
Competition for places at 11 is about 250/300 boys going for 60 places.
At 13 prep schools pre-select so competition in the exam is much less severe but they still have to come up to very high standard.
They do not have common entrance anymore because there are so many schools around here
They all set their own exams because they can ask more searching questions then CE or SP do.
SP ask the same topics but in a more searching way to find out how much a boy knows about the topic.
BTW DH school do not pre-select boys into who should do the scholarship stream that is done by prep school.
They have no influence which boys do scholarship stream or exam.
Prep schools do all the deciding, in this area anyway.
Which subjects do you specially want books for?
Hope that is of some help.
Let me know if you want any more help.
