Both my children, aged 15 and 18, did the quiz at the start which was pitched to make sure they got some questions right and some wrong, ensuring they read on, without feeling useless and clueless. We keep the book in the kitchen, and my children now do all their own laundry, to prove how mature they are. The straightforward practical tips are extremely good, for example on how to clean a loo, and the more sensitive areas are well handled - the sections on sex and drugs are good starting points for discussion.
