if you're saying worked solutions then...no worked solutions available
but then fitzpatrick doesn't have worked solutions either but at least most of the questions make some sense. fitz also has revision exercises and practice exam questions at the back of the book whereas cambridge doesn't have any practice exams but it does have alot of hard and impossibly difficult questions. just my opinion.
edit: i would still say use it as it can be useful for the equally shit hard questions 8-10 in the exam paper. i'm still using fitzpatrick, some maths in focus exercises, j&c and cambridge. but in terms of which one i favour the most between fitz, cambridge and coroneos, it would have to be fitz for the good examples, revision exercises and practice test papers.
