If you spend a little time on this site you will see an advert from an outfit called CAPT (run by one of our posters Paco). They are hele through and through.
They do training and books for all sorts of hele licences. They offer a PPL standard PofF book. Remember, it is not just passing the exam. P of F knowledge is needed to fly the thing properly too.
I am just a customer of theirs, so hopefully OK to mention......
