In my 14 year old daughter's High School along with lots of other schools I'm guessing, they now study Physical Education GCSE as the norm. Not like in my day! After one night being a asked barrage questions on homework in this field - Even if I went to the local gym, it still wouldn't prepare. I ordered this book - amazing, fantastic what can I say, live and learn. I'm so glad I have bought it at the beginning of her physical education studies before any sweat and tears. And for once my teenager was impressed with my 'interference' and to think I only bought it to my life easier. Love it..!
