thanks for that, WGS papers are not available on- line and have to be purchased(and also copyrighted) but I can tell you it makes MGS (Manchester Grammar School For Boys) considered to be the toughest paper 2 exams at 11+ (that can be downloaded from the school website) seem like "a walk in the park" in comparision!!
Good news is that the girl in question, who I am helping with her preparation, has already passes the Atrincham Girl's Grammar School, which standardises againt it's own cohert not the the national cohort, with a very good mark, but it is rather hard to see a girl crying because she is not scoring her usual 95%+ (has managed between 55%-60% in paper 2 and 90% in paper 1)and now refusing to sit the exam!!
I only have experience of 11+ GL papers so am unable to reassure honesty if she is on target or not, and admission officer not very helpful considering she is from a state school and local prep schools would have historical information on this type of thing
